Suprapineal recess diverticulum of the third ventricle exerting a mass effect on the midbrain and cerebellum

Ventricular diverticula usually occur secondary to chronic obstructive hydrocephalus, due to long-standing pulsating of cerebrospinal fluid against the ventricle wall. The medial wall of the atrium is more frequently involved, but other ventricle sites are at risk as well. We report on a 21-year-old...

Description
Summary:Ventricular diverticula usually occur secondary to chronic obstructive hydrocephalus, due to long-standing pulsating of cerebrospinal fluid against the ventricle wall. The medial wall of the atrium is more frequently involved, but other ventricle sites are at risk as well. We report on a 21-year-old woman with chronic headache and bilateral dysmetria. Magnetic resonance imaging showed a ventricular diverticulum on the posterior wall of the third ventricle with a cerebellar and midbrain mass effect. Her symptoms partially improved after endoscopic third ventriculostomy in the tuber cinereum region. Treatment of chronic hydrocephalus has been shown to improve the ventricular diverticulum symptoms in the patients in the literature.
