Neurologic diseases associated with lymphosarcoma in ten dogs.

Lymphosarcoma was diagnosed in 10 dogs with initial signs referable to the nervous system. Six dogs had signs of spinal cord disease, 2 had signs of peripheral nerve disease, and 2 had signs of cranial disease. The diagnosis of lymphosarcoma involving ther nervous system was made prior to the death of each dog, and necropsy confirmed the clinical diagnosis in each case. The clinical diagnosis was based on the results of blood analysis, bone marrow examination, lymph node cytology, cerebrospinal fluid evaluation, and tumor biopsy.
