Neurological symptoms, treatment and pathomorphology of primary and secondary metastatic brain neoplasm in dogs [Polish]

摘要

The neurological symptoms, treatment and neuropathology of primary gliosarcoma in a 12-year-old dog and carcinoma tubulare mammae, with secondary lung and brain metastases in a 7-year-old dog were presented. The primary CNS tumor was pinkish-white, soft, with a large (2.5 x 1.3 cm.) diameter, located in the subarachnoid space of the brain stem. Histological examination revealed a mixed character of the tumor (glio-mesenchymal) resembling gliosarcoma. This CNS tumor is associated with neurological symptoms and epilepsy. The other tumor, in the 7-year-old dog, was diagnosed as carcinoma tubulare mammae with metastases in the lungs and brain, and small areas of demyelization in the brain (near the lateral ventriculi), and in the white matter of the cerebellum. The presented cases of neoplasia in dogs with a manifestation of seizure activity and neurological symptoms indicate the necessity for performing wide diagnostic procedures. A dog patient with neurological symptoms should always be suspected of brain neoplasia disease, while cases with mammilla tumor might indicate secondary metastasis to the central nervous system.
