Abstract:
A 4-year-old male Toy Poodle was presented with a history of status epilepticus. On presentation, neurological examination revealed a delay in postural reactions in the right pelvic limb. Magnetic resonance imaging showed a fluid-containing cystic lesion that compressed the mesencephalon, hippocampus, and amygdala. The cyst was surgically removed via left rostrotentorial craniotomy. The final diagnosis was an intracranial ectopic choroid plexus cyst. The patient has remained free of seizures for 18 months after surgery. This is the first case report of an intracranial ectopic choroid plexus cyst that was surgically removed in a dog.
