摘要:

More than 30% (21 of 65) of German Shepherd dogs with clinical signs of cauda equina compression had radiographic and pathologic abnormalities compatible with osteochondrosis of the sacral endplate. Most of these dogs had a defect in the dorsal part of the sacral endplate and a detached bone fragment in the vertebral canal. Similar lesions were also found in growing and young adult dogs without clinical signs. The dogs with clinical signs of cauda equina compression also had severe degenerative disc disease with protrusion of the lumbosacral disc and compression of the cauda equina, suggesting that the signs of cauda equina compression more likely were related to the secondary degenerative changes (disc protrusions) rather than the primary disease. Clinically normal German Shepherds with sacral osteochondrosis usually were younger than 18 months, the dogs with cauda equina compression and sacral osteochondrosis older than 18 months (mean age 4.8 years). On the average, these dogs were two years younger as compared to dogs with cauda equina compression without sacral osteochondrosis. Male dogs are more often affected than females (5:1). There is a breed predisposition: in dogs other than German Shepherds, osteochondrosis of the sacral endplate seems to be extremely rare.

摘要:

The clinical, radiological and necropsy findings in a five‐year old dog with a hemangiosarcoma in the main pulmonary artery are described. Hemangiosarcoma in this location has not been previously described in the dog, the typical location in the heart being the right atrium and auricle. The tumor in this dog caused both a perfusion deficit to the right lung and obstruction of right ventricular outflow, which eventually caused right heart failur

摘要:

A radiographic study was performed on the maxilla of two healthy dogs to assess the effect of replacement of air by fluid and removal of conchae on the radiographic appearance. The purpose was to determine the significance of the presence or absence of the fine trabecular pattern on radiographs of the canine nasal cavity. The results indicate that the radiographic appearance of the maxillary conchae is primarily based on the presence of soft tissues covering the bony conchae, in combination with surrounding air. The radiographic appearance of the ethmoidal conchae is caused by the bony structures themselves. It is concluded that a loss of the characteristic parallel pattern in the cranial part of the nose is primarily the result of silhouetting of maxillary conchae by fluid. A loss of the fine trabecular pattern is caused by destruction of conchae.

摘要:

Foreign bodies in the soft tissues are frequent problems in both veterinary and human medical practice. Radiography has been the principle tool for diagnosis, but is unable to define many foreign bodies. This study was undertaken to compare the sonographic and radiographic visualization for a variety of foreign bodies. Fresh turkey muscle (pectoral and thigh) with skin was used as the soft tissue model. Assorted foreign bodies were introduced 1 cm into the muscle. Materials examined were small wood fragments, steel wire, glass, nails, graphite, rock, BB pellets, and polystyrene plastic. Following introduction of the foreign bodies radiographs were obtained and the specimens were studied sonographically at 5.0 mHz and 7.5 mHz. All foreign bodies were visible with sonography. A bright echo with either acoustic shadowing or reverberations was present for all specimens. Radiographically metallic foreign bodies were visible but wood, some graphite, and plastic were not seen. We conclude that radiography should remain the primary imaging modality for foreign body detection because of its general availability and low cost. If radiography is negative ultrasound can detect and guide the removal of radiolucent foreign bodies.

摘要:

This report compares results from imaging of transitional cell carcinoma of the urinary bladder in 15 dogs using intravenous urography, double‐contrast cystography, and ultrasonography. Intravenous urography demonstrated filling defects in the urinary bladder in 3 of the 5 cases examined with this modality. Double‐contrast cystography identified bladder masses in 8 of 10 animals. Ultrasonography was the only imaging modality which detected bladder masses in all patie
