Chylous ascites in three dogs.

Chylous ascites was diagnosed in 3 dogs. Mesenteric lymphangiography was performed in 2 dogs and helped delineate abnormalities of the lymphatic system. The cause of chylous ascites in each dog appeared to be different. In 1 dog, a ruptured mesenteric lymphatic was identified at surgery. Evidence of abdominal lymphatic obstruction was found in another dog. Chylous ascites in the third dog appeared to be a complication of mesenteric lymphangiography for chylothorax.

Diagnosis and treatment of Neospora caninum infection in a dog.

Neospora caninum, a protozoan organism, caused extensor rigidity of the pelvic limbs in a 12-week-old dog. Diagnosis was based on results of muscle biopsy, neuroelectrodiagnostics, serotesting, and cell culture. Indirect fluorescent antibody (IFA) titer to N caninum was 1:800 at time of admission and 1:3,200 after 4 and 6 weeks. A reciprocal IFA titer of 50 to N caninum was also found in the CSF. Serotesting for T gondii was negative. Treatment with clindamycin followed by sulfadiazine and trimethoprim did not change the pelvic limb extensor rigidity, but other signs of minor neurologic dysfunction improved.

Clinical, echocardiographic, and radiographic findings of peritoneopericardial diaphragmatic hernia in two dogs and a cat.

Peritoneopericardial diaphragmatic hernia was diagnosed in 2 dogs and a cat. One dog was referred because of clinical signs of cardiac tamponade and acute decompensation from liver entrapment within the hernia. Surgical correction of the hernia alleviated clinical signs in all 3 animals. Echocardiography was used in combination with radiography to provide a rapid and accurate diagnosis.

Disseminated meningeal tumor in a dog.

A 6-year-old Golden Retriever was referred for evaluation of hind limb paresis and generalized weakness. Neurologic examination revealed multifocal cervical and lumbosacral spinal disease. Radiography and myelography failed to identify a lesion. Cerebrospinal fluid was markedly cellular and had a high protein concentration, consistent with myelitis or a neoplastic process. The dog did not improve with medical management. Gross and histologic examination of the brain and spinal cord revealed a thick meningeal surface characterized by polymorphic histiocytic-like cells to multinucleate giant cells. The neoplastic process was considered to be a disseminated meningeal polymorphic cell sarcoma.
