Pathological findings in intracranial tumours in dogs: 13 cases.

摘要

In the study, macroscopic and microscopic diagnosis was obtained in intracranial tumours from 13 dogs. These dogs (8 males and 5 females) were between 4-14 years old and did not belong to brachycephalic breeds except for 2 dogs. The primary brain tumours identified were meningiomas (n=5), choroid plexus papilloma (n=3) and glial tumours (3 astrocytomas and 1 oligodendroglioma) and a same dog exhibited simultaneously 2 distinct types of brain tumours, i.e. papilloma and oligodendroglioma. In addition, 2 secondary tumours (squamous cell carcinoma and anaplastic carcinoma) were also diagnosed and resulted from direct expansion of sinus tumours.
