title: Trapped fourth ventricle in an adult: radiographic findings and surgical treatment.
abstract: Trapped fourth ventricle is a rare entity that has most often been reported mainly in children as a late complication of lateral ventricle shunting. We report a case in a previously normal adult who developed symptoms several months after bacterial meningitis. Unique radiographic and surgical findings are discussed, and recommendations are made for the classification and treatment of fourth ventricular enlargement.
