MAGNETIC-RESONANCE-IMAGING IN A DOG WITH CHOROID-PLEXUS CARCINOMA

Choroid plexus carcinoma was diagnosed in a 10-year-old maltese dog wi th chief complaint of progressive ataxia and head tilt. No abnormalite s was observed on hemogram, radiographs of the skull, and electroencep harograph (EEG). Neurological examination suggested central vestibular lesions. On the magnetic resonance imaging (MRI) examination, images after contrast enhancement with Gadolinium DTPA-dimeglumine showed a r ough circular lesion with an increased signal intensity in caudal foss a. This lesion was histopathologically confirmed to be choroid plexus carcinoma.
