Extrahepatic biliary tract rupture: evaluation of the relationship between the site of rupture and the cause of rupture in 15 dogs.

We performed a retrospective study of 15 cases of extrahepatic biliary tract rupture in dogs. Nine of the 15 dogs had ductal rupture associated with blunt abdominal trauma. The remaining 6 dogs had gallbladder rupture associated with cholelithiasis and/or cholecystitis. The relationship between site of rupture and cause of rupture was significant (p = 0.0002). A review of 60 dogs with extrahepatic biliary tract rupture reported in the veterinary literature revealed a similar relationship (p = 0.0001). Thirty-two of 33 cases of ductal rupture were associated with blunt abdominal trauma and 25 of 27 cases of gallbladder rupture were associated with cholelithiasis and/or cholecystitis. Totals after combining our cases with those from the literature suggests the most frequent area of ductal rupture is the common bile duct distal to the last hepatic duct, followed by the junction of the common bile duct with the duodenum.

Primary vertebral hemangiosarcoma in a dog.

A 7-year-old spayed Cocker Spaniel was evaluated for recurrent hind limb paraplegia. Radiography and myelography revealed a compression fracture of T-9 secondary to a lytic process. Findings at necropsy and histologic and immunohistochemical examinations revealed 3 sites of hemangiosarcoma in each of the bodies of T-9 to T-11. Primary vertebral hemangiosarcoma is rare, and in this dog may have represented a multicentric occurrence or a primary neoplasm with adjacent metastatic foci.

Nuclear medical bone imaging and targeted radiography for evaluation of skeletal neoplasms in 23 dogs.

Nuclear medical bone imaging was used in combination with targeted radiography to detect metastatic or multicentric lesions in 23 dogs with skeletal neoplasms. Each dog with a radiographically diagnosed skeletal neoplasm was injected with Technetium-99m labeled methylene diphosphonate (99mTc-MDP) (15.0 mCi intravenously) for whole body imaging. All areas with increased uptake of 99mTc-MDP were radiographed. In 19 dogs, the amount of bone shaft involvement in primary sites indicated by bone imaging was larger than the amount indicated by radiography. Eighteen dogs had secondary areas of increased 99mTc-MDP uptake, six of which had secondary areas that were suspected radiographically to be neoplastic. Four dogs had lesions characterized histologically as neoplasia, one as bone infarction and one as normal cortical bone. Positive predictive value for this strategy was 66.7%. Results of this study suggest that nuclear medical bone imaging with targeted radiography is a quick, noninvasive technique with a good positive predictive value for evaluation of the skeleton for metastatic or multicentric sites of neoplasia.
