title: Quadrigeminal cyst management by cystoperitoneal shunt in a 4-year-old Persian cat.
abstract: Quadrigeminal cysts represent intracranial cystic accumulations of cerebrospinal fluid within the arachnoid mater at the level of the quadrigeminal cistern. Quadrigeminal cysts are rare in cats, with only one previous report in the veterinary literature. A 4-year-old, male-neutered Persian cat was presented with a 1-year duration of initially episodic, but later progressive, obtundation and collapse. Magnetic resonance imaging of the brain revealed a quadrigeminal cyst with marked compression of the adjacent neural structures, cerebellar herniation and obstructive hydrocephalus. Cystoperitoneal shunt placement was performed after the cat became refractory to medical therapy and this resulted in return of normal neurological status. The improvement in the neurological deficits following placement of a cystoperitoneal shunt in this case appeared to be correlated with resolution of the secondary effects (in particular the obstructive hydrocephalus) rather than resolution of the quadrigeminal cyst. Cystoperitoneal shunt placement was an effective long-term treatment option for the management of the quadrigeminal cyst in this cat.
