Partial intestinal obstruction due to colonic adenocarcinoma in a cat.

An abdominal mass was palpated in a 14-year-old, spayed female cat with unresolving diarrhea and decreased appetite. A stricture of the ascending colon was confirmed radiographically, identified upon laparotomy, and resected. Colonic adenocarcinoma with infiltration into lymphatics was diagnosed histologically. Eight months postoperatively, the subject was clinically normal.     

Splenic foreign body in a cat

An 8-year-old domestic shorthair cat was evaluated for a several day history of anorexia and vomiting. Abdominal distention was noted on physical examination and diagnostics including abdominal radiographs and abdominal ultrasound demonstrated the presence of free fluid in the peritoneal cavity. Septic peritonitis was diagnosed on cytologic evaluation of the peritoneal fluid. The cat was taken to surgery and a foreign body composed of plant material was found embedded within the spleen. A splenectomy was performed and both open and active peritoneal drainages were used to successfully treat this case.     

Nasopharyngeal trichobezoar foreign body in a cat

CASE SUMMARY: A 5-year-old male neutered indoor cat presented for evaluation and treatment of an acute onset of nasal discharge and open-mouth breathing of 3 days' duration. He had been treated for asthma prior to presentation, but his clinical signs were more consistent with upper airway disease. Thoracic radiographs were suggestive of asthma. However, a soft tissue mass was noted in the nasopharynx on a lateral cervical radiograph. Nasopharyngeal examination revealed the mass to be a trichobezoar (hair ball) lodged in the nasopharynx, removal of which led to resolution of clinical signs. The cat re-presented with a second nasopharyngeal trichobezoar approximately 1 year later, which was also successfully removed. CLINICAL SIGNIFICANCE: Nasopharyngeal disease has myriad potential infectious, inflammatory and neoplastic etiologies. However, simpler causes such as foreign bodies can be considered in cases of acute-onset nasopharyngeal disease. To the authors' knowledge, this is the first reported case of a nasopharyngeal trichobezoar foreign body in a cat.     

Chronic oesophageal foreign body in a cat

An 11-year-old cat was presented with an approximately 2-month history of dysphagia, intermittent regurgitation and weight loss. An oesophageal foreign body was identified on plain radiographs, and an oesophagotomy was performed to remove a large V-shaped bone from the caudal cervical oesophagus. A gastrostomy feeding tube was placed to allow nutritional support postoperatively. Medical treatment for oesophagitis was initiated after surgery. No complications were encountered and the cat was discharged 4 days after surgery.     

Exophthalmos due to a wooden foreign body in a dog

An 8-year-old Golden Retriever dog was presented with a 10-month history of right-sided exophthalmos. Radiographs and CT demonstrated a linear density, suggestive of a foreign body, in the region of the ramus of the right mandible. A 7 cm stick, located medial to the right zygomatic arch, was removed during exploratory surgery. The dog recovered with the aid of antibiotics, however was left with a residual facial nerve paralysis.     

Tracheal foreign body in a cat: a case report

An unusual tracheal foreign body in a cat and the problems associated with its removal is described. A review of other documented feline tracheal foreign bodies is included.     

Bilateral ureteral obstruction in a cat due to a ureteral transitional cell carcinoma

A 15-year-old cat was presented with a history of lethargy and vomiting. Serum biochemistry revealed severe azotemia. Ultrasonography revealed a small left kidney and hydronephrosis of the right kidney. There was an abdominal mass between the kidneys. Necropsy revealed a mass circumflexing both ureters and histopathology confirmed a diagnosis of transitional cell carcinoma.     

Retrobulbar lymphoma associated with a ballistic foreign body in a cat

A seven‐year‐old domestic shorthair cat, adopted 5 years previously with a corneal perforation of the left eye, was presented for investigation of a left orbital mass. Computed tomography revealed a metallic foreign body within a contrast‐enhancing, heterogeneous orbital mass. Large cell lymphoma was diagnosed from a fine needle aspirate. The cat staged negatively and was treated with l‐asparaginase, prednisolone and three fractions of radiation therapy. A rapid clinical remission was obtained and the cat remained in remission for 3 years after therapy. This is the first report of large cell lymphoma likely occurring secondary to a foreign body.     

C-arm fluoroscopy for the removal of an intraorbital foreign body in a cat

This report describes the clinical manifestations, diagnosis and minimally surgical intervention of a cat with an intraorbital foreign body. A spayed female cat of unknown age was presented with a recurrent cutaneous sinus tract of the left suborbital region. The cat had not vocalized at all since the adoption. A sharp-edged radiopaque foreign body was visualized on dental radiography. Computed tomography outlined the length of the foreign body from the intraorbital soft tissue to the pharynx. The foreign body was removed under the guide of C-arm fluoroscope with minimal skin incision. The surgical site healed completely on the 11th postoperative day, and the cat vocalized normally after healing.     

Successful surgical management of a perforating oesophageal foreign body in a cat

CASE PRESENTATION AND SURGICAL INTERVENTION: a 3-year-old cat was presented with a recent history of dysphagia and intermittent regurgitation. Radiography revealed a bony oesophageal foreign body at the level of the thoracic inlet. Endoscopic retrieval was attempted but resulted in severe dyspnoea due to the development of pneumomediastinum, pneumothorax and subcutaneous emphysema secondary to perforation of the oesophageal wall. Immediate surgical exploration was carried out. Extensive necrosis of the oesophagus resulting from the presence of the foreign body led to a decision to perform an oesophageal resection and anastomosis. CLINICAL RELEVANCE: this is the first clinical report of a cat treated successfully by oesophagectomy following oesophageal perforation due to an obstructive foreign body. The authors suggest that prompt surgical intervention, the ability to convert to a surgical procedure under the same anaesthetic as a non-surgical retrieval, placement of a gastrostomy tube and the availability of advanced anaesthetic and critical care support are important factors to consider when managing feline patients with a perforating oesophageal foreign body.     

Aortic foreign body (airgun pellet) embolism in a cat

A five-year-old female domestic shorthair cat presented with clinical signs typical of an aortic saddle thromboembolism. An echocardiogram and thoracic radiographs excluded cardiac disease as a source of the thrombus. Two heavy metal opacity, pellet-like objects were seen in the thoracic and abdominal radiographs. Abdominal ultrasound demonstrated occlusion of aortic blood flow by the abdominal pellet but could not indicate whether this was due to a penetrating aortic wound or pellet embolisation. A necropsy confirmed a penetrating left ventricular cardiac wound with subsequent embolisation of the pellet to the abdominal aorta.     

Partial uterine prolapse associated with uterine foreign body in a cow

After correction of partial uterine prolapse in a Holstein cow, a 6-cm-long twig was found deep in the affected uterine horn. The twig was removed, and calcium-dextrose and penicillin G were administered. Recovery was unremarkable. Other reports of uterine foreign bodies in cows are scarce and do not describe uterine foreign bodies associated with uterine prolapse or invagination.
