Communicating Fourth Ventricular Hydrocephalus: Case report

  • Nobuhiko Aoki


It has been recognized that shunting of the lateral ventricles for communicating or noncommunicating hydrocephalus can be, although rarely, complicated by the development of an abnormally enlarged fourth ventricle. This is referred to as double compartment hydrocephalus, isolated fourth ventricle, or trapped fourth ventricle. This process is said to be caused by occlusion of the aqueduct of Sylvius and the fourth ventricular outlets or the subarachnoid spaces in the posterior fossa. The clinical presentations include cerebellar signs and brain stem dysfunction due to compression by the distended fourth ventricle.
