A 6 month-old dog was examined for progressive paraparesis. On physical examination bony malformations were palpated over the cranial lumbar vertebral bodies and on the left metatarsal bone. Neuroanatomic lesion localization for the paraparesis was a T3-L3 spinal cord lesion. Radiographs confirmed bony masses at L1-L2 and on the left 3rd metatarsal bone. Magnetic resonance imaging was performed from T3-L3. Severe spinal cord compression was identified at L1-L2. Surgical decompression and biopsy confirmed the mass to be cartilaginous exostoses. This paper is an example of cartilaginous exostoses imaged with MR. 相似文献

Azygos continuation of the caudal vena cava was identified via ultrasonography and angiography in a 7 month old female boxer. Azygos continuation of the caudal vena cava is a rare vascular anomaly that results from failure of anastomosis between the caudal cardinal system and the right vitelline vein during embryogenesis. This anomaly has also been described in association with portoazygos shunt. 相似文献

A report of a cat with a true diaphragmatic hernia in which only falciform fat had herniated is pressented. The lession was misinterpreted as a pulmonary mass. Additional radiographic studies which may have been of diagnostic benefit are briefly discussed. 相似文献

Difficulty in recognition of some diaphragmatic hernias in dogs have stimulated the authors to develop a diagnostic method consisting of selective angiography of the cranial mesenteric and celiac arteries. The basis for the experimen was that each herniated visceral organ is usually displaced with its vessels. The experiment was carried out on 14 mongrel dogs. Four dogs served as controls. Different kinds of diaphragmatic hernias were surgically created in 10 dogs. Survey abdominal radiographs, gastrointestinal tract contrast studies and selective abdominal angiography were performed 14 days later. In angiograms of dogs with omental diaphragmatic hernias, displacement of branches of the left gastroepiploic artery into the thorax was seen. In angiograms of dogs with hepatic diaphragmatic hernias, branches of the common hepatic artery were seen to enter the thorax. In dogs with herniated small intestine, the jejunal branches of the cranial mesenteric artery were seen entering the thorax. Potential possibilities of selective abdominal angiography for diagnosis of diaphragmatic hernias are discussed. 相似文献

TREATMENT OF DIAPHRAGMATIC HERNIA IN BUFFALOES 总被引:2,自引:0,他引:2

The surgical treatment of diaphragmatic hernia attempted on 19 lactating buffaloes is described. Thirteen cases recovered uneventfully, 1 recovered after developing brisket oedema and 5 died, 3 during surgery and 2 postoperatively. The desired depth of anaesthesia was achieved by the administration of 6% chloral hydrate followed by 5% thiopentone sodium. A postxiphoid approach and the use of a continuous lock stitch suture were preferred to repair the vent in the diaphragm. Pre- and post-operative use of hydrocortisones and fluids and sufficient tissue oxygenation by controlled positive pressure respiration are believed to be keys to the success of the treatment adopted. 相似文献

Ten clinically normal adult mongrel dogs were examined using lumbosacral epidurography in an effort to determine a reproducible technic and a normal radiographic appearance. The site of contrast medium injection was the ventral epidural space at the sacrococcygeal junction or the cranial coccygeal region. An initial dose of 0.15 ml/kg of metrizamide for the right lateral recumbent radiograph with 0.10 ml/kg additional metrizamide for additional right lateral or the subsequent dorsoventral radiographs was considered adequate. Two numerical values were observed for each normal epidurogram: the sacrovertebral angle; the ratio of the contrast medium column width to L6 body length. A statistically significant relationship between hindlimb positioning and the numerical value of the sacrovertebral angle was identified. Some advantages of epidurography for delineating the lumbosacral area are obvious: (1) it overcomes the limited value of lumbosacral area myelography; (2) it is technically easier than intraosseous vertebral venography; (3) there is minimal patient trauma; (4) there was no apparent adverse sequela to repeated contrast medium injections. 相似文献

A twelve-year-old neutered male beagle presented for a cranial abdominal mass. The results of physical examination, laboratory tests, radiography, and ultrasonography are presented. A torsion of the quadrate lobe of the liver was diagnosed at surgery and confirmed by histopathology. A brief discussion of liver lobe torsion is presented. 相似文献

A two-year-old intact male Brittany Spaniel was admitted for evaluation of progressive spinal pain. Previous treatment had been initiated for suspected lumbosacral intervertebral disk disease, however there was poor response to therapy. On presentation the dog was laterally recumbent and neurological examination revealed hyperesthesia over the lumbar vertebral segments. On survey radiography there was loss of detail in the sublumbar fascial planes and inconclusive lumbar vertebra proliferation. Magnetic resonance (MR) imaging was performed to better evaluate the lumbar spine and surrounding tissues, which revealed extensive paralumbar cellulitis, abscessation and osteomyelitis with extradural compression of the spinal cord. MR imaging allowed delineation of the abscessed area, and distinct visualization of its extension into and involvement of the surrounding tissues including muscle, fat, and retroperitoneal structures. In this case, MR imaging was instrumental in defining the extent of the infection and determining whether medical or surgical management of the diseased tissue was necessary. If available, MR may be the imaging method of choice for evaluation of paraspinal abscesses yielding a better insight to the spinal structures involved and facilitating medical or surgical intervention. 相似文献

Real–time ultrasonography was used to confirm diaphragmatic rupture in a horse that developed pleural effusion following a traumatic event. Pleural effusion, a cranially displaced crus, and a cranially positioned sacculated loop of bowel were seen radiographically. The presence of gas–filled intestine cranial and dorsal to the diaphragm was detected by ultrasound imaging. The use of ultrasound and radiography in the diagnosis of diaphragmatic rupture is discussed. 相似文献
