A two‐year‐old Jack Russell terrier was presented for evaluation of chronic cough and exercise intolerance. Previous treatment with antibiotics and glucocorticoids had only partially ameliorated the clinical signs. During investigation, hypoxaemia, peripheral eosinophilia and an eosinophilic bronchoalveolar lavage fluid were noted. Thoracic radiographs revealed two ovoid clearly delineated soft‐tissue opacities, one in the caudal segment of the left cranial lung lobe (diameter 26 mm) and the other in the right cranial lung lobe (diameter 20 mm). These findings were verified by computed tomography, which identified an additional smaller lesion (diameter 16 mm) dorsally in the right caudal lobe. Ultrasound‐guided fine‐needle aspiration samples confirmed the diagnosis of eosinophilic pulmonary granulomatosis and treatment with prednisolone and azathioprine was initiated. Within 1 month, granulomas were no longer detectable radiographically. All medication was discontinued after 7 months and currently, after 2·5 years, the dog remains free of clinical signs. To the authors’ knowledge this is the first case report to describe prolonged remission from idiopathic canine eosinophilic pulmonary granulomatosis. 相似文献

Idiopathic hypereosinophilic syndrome (HES) is a rare syndrome for which Rottweilers appear to over-represent the canine cases. A 6-month-old female entire Rottweiler presented with seizures following a traumatic incident. The dog was identified as having a marked, sustained eosinophilia and investigations did not identify an underlying cause. Concurrently, the dog had chronic eosinophilic hepatitis with impaired liver function and mesenteric eosinophilic lymphadenitis. The dog went on to have spontaneous resolution of HES and normal liver function was subsequently documented. To date, the dog is still alive, more than 4 years after initial presentation. The diagnosis of idiopathic HES in Rottweilers may not carry a poor prognosis and the condition may spontaneously resolve, even in cases with documented organ damage. 相似文献

A haematological disorder in a dog characterised by a massive leucocytosis, mainly composed of eosinophils and their precursors is reported here. The normal composition of cells in the bone marrow was displaced in favour of the eosinophils and their precursors. No apparent cause for the pronounced eosinophilia could be determined by clinical, haematological, clinical-chemical, radiological or pathological examinations. A diagnosis of eosinophilic leukaemoid reaction was suggested as the criteria for the diagnosis of eosinophilic leukaemia in the dog but this was not firmly established. 相似文献

The first known report of synovial fluid eosinophilia in a dog is described here. The occurrence of eosinophils in joint fluid is rare. Sporadic cases have been recorded in humans and most can be related to immunemediated reactions, both parasitic and non- parasitic. The dog in this case report had 20-52% eosinophils in multiple joints, as well as hemarthrosis and marked mononuclear cell reactivity. An intense peripheral eosinophilia was demonstrated one week later. The associated lameness resolved with non-steroidal anti-inflammatory therapy. Lack of remarkable history or other clinical symptoms led to a diagnosis of idiopathic, eosinophilic, polyarthritis, likely immune-mediated. 相似文献

Extreme eosinophilia with disseminated eosinophilic granulomatous disease is described in a 4-year-old Arabian mare. Clinical signs included weight loss, coughing, jugular distention, and ventral edema. Cutaneous lesions were not observed. Eosinophilic inflammation was observed in cytologic specimens from the respiratory tract, body cavities, and lymph nodes. At necropsy, a 20-cm diameter intrathoracic mass was observed. Smaller nodules were present in the lymph nodes, liver, spleen, adrenal glands, pancreas, and skeletal muscle. Histologically, these masses and nodules were characterized by infiltrates of eosinophils, macrophages, and multinucleated giant cells, reactive fibroplasia; and multifocal eosinophilic coagula. Microscopically, mild eosinophilic infiltrates were observed in sections of stomach, small intestine, colon, and pleura; however, gross lesions were not observed in these tissues at necropsy. The etiology of the extreme eosinophilia and disseminated eosinophilic granulomatous disease in this horse was not determined. 相似文献

A 1‐year‐old, female intact Pug dog was presented to the Small Animal Teaching Hospital of the University of Liverpool with a 4‐week history of progressive multifocal intracranial signs. Magnetic resonance imaging (MRI) detected multiple hemorrhagic lesions in the brain. The Baermann and zinc sulfate flotation tests with centrifugation, performed on fecal samples, were positive for lungworm larvae and an antigenic test confirmed Angiostrongylus vasorum infection. Anthelmintic treatment was started with a consequent marked clinical improvement. Seventy days later, the dog was clinically normal, and no larvae were detected on the Baermann test. Repeat MRI of the brain revealed marked improvement of the hemorrhagic lesions. Cerebrospinal fluid analysis (CSF) showed marked eosinophilic pleocytosis, and anthelmintic treatment was restarted. A follow‐up CSF analysis 4 months after the first presentation revealed resolution of the eosinophilic pleocytosis. This is the first case report of marked eosinophilic pleocytosis associated with neural A vasorum infection in a dog. The CSF eosinophilic pleocytosis persisted for several weeks after treatment, even in the absence of concurrent clinical signs and with a negative A vasorum Baermann test. 相似文献

Eosinophilic enteritis in a specific-pathogen-free cat 总被引:2,自引:0,他引:2
Moderate to severe, chronic, segmental eosinophilic enteritis was diagnosed histopathologically in a 2-year-old, specific-pathogen-free cat. Peripheral eosinophilia was not observed, although eosinophilic infiltrates were found in mesenteric lymph nodes. Typical gastrointestinal signs characteristic of this disease (diarrhea, vomiting, and anorexia) were not seen; only weight loss was observed. Treatment was not instituted. Previously reported cases of feline eosinophilic enteritis have been associated with several domestic breeds having a diversity of backgrounds. The cat of this report had a known genealogy and disease-free history, was reared under barrier conditions, and was fed a restricted diet. The cause of the disease in this cat was not determined. 相似文献

This is a case of coccidioidomycosis in a dog, examined for vomiting and labored breathing. Physical examination and thoracic and abdominal imaging revealed pleural and peritoneal effusions, both of which exhibited neutrophilic inflammation with a substantial eosinophilic component. The dog had positive IgM and IgG coccidioidomycosis titers at initial evaluation. The eosinophilic component of the inflammation was attributed to coccidioidomycosis. The dog underwent approximately 6 months of fluconazole treatment, with both effusions and clinical signs improving after 6 weeks. Three months after cessation of antifungal treatment, the dog developed a mid-diaphyseal lytic and proliferative lesion in the left radius caused by Coccidioides spp. This case illustrates the importance of consideration of coccidioidomycosis when an eosinophilic cavitary effusion is present in dogs that live in or have traveled to endemic regions. 相似文献

A 10-year-old, neutered female, domestic shorthair cat was presented with a recent history of weight loss, polydipsia, diarrhoea and vomiting. On physical examination, intestinal thickening and mesenteric lymph node enlargement were apparent. Clinical investigations revealed peripheral blood eosinophilia, eosinophilic abdominal effusion and eosinophilic mesenteric lymphadenitis. There was a temporary response to treatment with glucocorticoids but signs progressed and the cat was euthanased. On histology, there was eosinophilic infiltration and fibroplasia of intestine and mesenteric lymph nodes. Large aggregates of neoplastic round cells in the intestine and lymph nodes were identified as T lymphocytes using immunohistochemistry. A diagnosis of intestinal T cell lymphosarcoma was made. This case demonstrates that hypereosinophilic paraneoplastic syndrome may occur in cats with lymphosarcoma. Eosinophil chemotaxis may be a response to the production of interleukin-5 by neoplastic lymphocytes. 相似文献

True idiopathic hypereosinophilic syndrome has been described in human beings and cats, but not in dogs. The syndrome is characterised by prolonged unexplained peripheral mature eosinophilia, the infiltration of many organs by eosinophils, organ dysfunction and a fatal outcome. This paper describes an idiopathic disseminated eosinophilic disease in a dog involving various organs, manly the heart and the lungs, accompanied by a leukemoid eosinophilic response, and a fatal outcome. The histopathological findings included the infiltration of the myocardium, lung parenchyma, liver, spleen, lymph nodes and skeletal muscles with eosiniphils. 相似文献

Background: Eosinophilic inflammation of the gastrointestinal tract of dogs occurs in numerous disorders, typically resulting in diffuse intestinal thickening. Rarely, eosinophilic masses have been reported.
Objective: Describe a series of dogs with 1 or more idiopathic eosinophilic gastrointestinal masses (IEGM) to better characterize the clinical features, treatment, and prognosis.
Animals: Seven dogs with 1 or more gastrointestinal masses composed primarily of eosinophilic infiltrates for which no underlying cause was found.
Methods: Retrospective case series.
Results: Rottweilers and purebred, large breed dogs predominated. Dogs were middle-aged and typically had chronic signs of upper or lower gastrointestinal disease. Decreased appetite, vomiting, and evidence of gastrointestinal hemorrhage were present in the majority of cases. An abdominal or rectal mass was frequently noted on physical examination. Common laboratory abnormalities included peripheral eosinophilia, mature neutrophilia, hypoproteinemia, and hypocholesterolemia. The masses were histologically composed of moderate to severe eosinophilic infiltrates, which were often transmural and accompanied by fibrosis. All dogs treated with surgery alone died of complications of their disease. Treatment with corticosteroids and ivermectin improved clinical signs, caused resolution of eosinophilic infiltrates, and prolonged survival in most dogs treated medically.
Conclusions and Clinical Importance: These findings suggest that the prognosis for dogs with IEGM may be good when recognized and managed appropriately. When surgery is performed, medical treatment should also be added. 相似文献

A 5-month-old female Kelpie developed paraparesis, hind limb ataxia and spinal hyperaesthesia 4 days after ovariohysterectomy. Neurological examination demonstrated upper motor neuron signs in the pelvic limbs with lower motor neuron signs in the tail. Cerebrospinal fluid analysis demonstrated an increased protein concentration and marked eosinophilic pleocytosis. The dog was known to have eaten rats, snails and slugs. A tentative diagnosis of neural angiostrongylosis was made and later confirmed using an ELISA based on soluble antigens obtained from larval 4 Angiostrongylus cantonensis. Antibody titres from the patient's serum and CSF were 800 and 6400, respectively. The dog was treated successfully with prednisolone. ELISA testing of serum may provide a non-invasive means for diagnosing neural angiostrongylosis in dogs. 相似文献

An eosinophilic granulomatous pneumonia is described in a German shepherd dog. On thoracic radiographs and at post mortem examination disseminated pulmonary tumour-like nodules had been seen. Histologically the nodules consisted of macrophages, eosinophils, plasma cells and occasionally giant cells. In plasma cells and macrophages, large amounts of immunoglobulin G and immunoglobulin M could be demonstrated. An aetiology could not be determined, but vasculitis and cytology made an allergic reaction of type 1 and, or, type 3 most likely. The classification of pulmonary infiltration with eosinophilia (PIE-syndrome) is discussed. 相似文献

A 5-year-old female spayed Shetland Sheepdog Mix dog was evaluated for a history of recent seizure activity, progressive hind limb ataxia, polyuria, and polydipsia and no history of gastrointestinal signs. Physical examination findings included conscious proprioceptive deficits, ataxia, and anterior uveitis along with a hypermature cataract in the right eye. Results of a CBC, serum biochemical profile, urinalysis, and computed tomography scan of the brain were unremarkable. Cerebrospinal fluid (CSF) analysis revealed marked eosinophilic pleocytosis and rare organisms consistent with Prototheca spp within neutrophils and macrophages. On postmortem histologic examination, mononuclear inflammation and numerous intralesional algal organisms, similar to those seen on the cytologic preparation of CSF, were found in the brain, eyes, kidneys, and heart. Abnormalities were not detected on gross and histologic examination of the gastrointestinal tract. Cultures of CSF and subdural/olfactory bulb, but not intestinal tract, yielded growth of Prototheca spp, and PCR analysis and DNA sequencing confirmed the organism as Prototheca zopfii genotype 2. We have reported a rare case of disseminated protothecosis that was diagnosed by evaluation of CSF in a dog presented with neurologic signs and no overt enteric disease. Protothecosis should be considered as a rare cause of seizures, even in the absence of obvious enteric signs, and should be included in the differential diagnosis of eosinophilic pleocytosis. 相似文献

Eosinophilic intestinal diseases of the horse are not commonly reported. Similar diseases are reported in man, but for either species, these eosinophilic diseases, are poorly understood. Eosinophilic intestinal disease may be accompanied by eosinophilic disease of other organs, or eosinophilia may be restricted to the intestine. When infiltration of eosinophils is restricted to the intestine, horses have a good prognosis for resolution of clinical signs, even though the treatment may include celiotomy with intestinal decompression or resection and administration of a corticosteroid. When eosinophilic intestinal disease is accompanied by infiltration of other organs, such as skin, pancreas, lungs or liver, the horse's prognosis for survival is very poor. 相似文献

Seven cats were presented for mild-to-moderate cough and/or dyspnoea after starting bromide (Br) therapy for neurological diseases. The thoracic auscultation was abnormal in three cats showing increased respiratory sounds and wheezes. Haematology revealed mild eosinophilia in one cat. The thoracic radiographs showed bronchial patterns with peribronchial cuffing in most of them. Bronchoalveolar lavage performed in two cats revealed neutrophilic and eosinophilic inflammation. Histopathology conducted in one cat showed endogenous lipid pneumonia (EnLP). All cats improved with steroid therapy after Br discontinuation. Five cats were completely weaned off steroids, with no recurrence of clinical signs. In one cat, the treatment was discontinued despite persistent clinical signs. The cat presenting with EnLP developed secondary pneumothorax and did not recover. Br-associated lower airway disease can appear in cats after months of treatment and clinical improvement occurs only after discontinuing Br therapy. 相似文献

Eght dogs were orally superinfected for 1 month with 50,000 embryonated Toxocara canis ova. Results of laboratory examinations during inoculation and for 2 weeks postinoculation revealed moderate leukocytosis, marked absolute eosinophilia, hypoalbuminemia, increased concentrations of serum glutamic pyruvate transaminase, and in 2 dogs, precipitating humoral antibodies. Other changes were moderate ascites, hepatomegaly, lymphadenopathy, and focal lesions (0.5 to 3.0 mm) in liver, lung, kidney, intestine, abdominal lymph node, heart, diaphragm, and spleen. Microscopically, focal eosinophilic gastroenteritis was produced. Eosinophils and globule leukocytes were increased throughout the intestinal mucosa. Eosinophil-infiltrated and granulomatous lesions were in the same organs listed as having focal lesions, as well as in the pancreas. The importance of serum beta-globulin content as a potential diagnostic tool was emphasized, and the experimentally induced infection was compared with naturally occurring eosinophilic gastroenteritis in the dog. 相似文献

Eosinophilic bronchopneumopathy (EBP) is a disease characterized by eosinophilic infiltration of the lung and bronchial mucosa, as demonstrated by examination of bronchoalveolar lavage fluid cytologic preparations or histologic examination of the bronchial mucosa. Although the precise cause of EBP is unknown, a hypersensitivity to aeroallergens is suspected. The diagnosis relies on typical history and clinical signs, demonstration of bronchopulmonary eosinophilia by cytology or histopathologic examination, and exclusion of known causes of lower airway eosinophilia. Most dogs display an excellent response to oral corticosteroid therapy; however, side effects of this treatment can be limiting. New therapeutic approaches are being studied, including the use of aerosol therapy, cyclosporine, or drugs interfering with T helper 2 immune response. 相似文献

Three Rottweilers with marked peripheral eosinophilia and infiltration of the liver, spleen, lungs, and bone marrow with eosinophils were diagnosed with idiopathic hypereosinophilic syndrome (IHES). Mean serum immunoglobulin E concentrations were markedly high. On cytogenetic analysis, no evidence of karyotypic abnormalities was found in bone marrow aspirates. Despite an extensive search, no underlying cause for the eosinophilia could be identified. In this study, cytogenetic analysis and measurement of serum IgE concentrations were used to differentiate IHES and eosinophilic leukemia. 相似文献
