Abstract

A 6-year-old female Boston terrier dog was presented with seizure episode, forelimb paraparesis, excessive panting, and ataxia. On physical and neurological examination, episcleral vessel engorgement, delayed postural reaction, delayed pupillary light reflex (both direct and consensual), and crossed forelimb were noted. Serum biochemical profiles were not remarkable other than mildly elevated hepatic enzymes. On cerebrospinal fluid analysis, elevated protein concentration was observed. In magnetic resonance imaging scans, the left frontal brain lesion with ring enhancement strongly suggested the presence of intracranial tumor. Concurrently, secondary hydrocephalus and syringomyelia were also observed. The dog was euthanized at 4 months after initial presentation because of aggravated neurological signs. This case was definitely diagnosed as an intracranial anaplastic oligodendroglioma based on postmortem histopathologic examination.
