SYMPTOMATIC TETHERING OF THE CEREBELLAR VERMIS - CASE-REPORT

A 25-YEAR-OLD MAN with symptomatic tethering of the cerebellum is pres ented. At the age of 8 days, the patient underwent a limited repair of a posterior fossa encephalocele. He was well until the age of 24 when he began to experience paroxysms of extremity weakness, progressive i ncoordination, and pain at the base of the skull. Imaging demonstrated a connection between the cerebellar vermis and the subcutaneous tissu e underlying the site of the previous encephalocele repair. Exploratio n of the area with the release of a fibrous stalk resulted in the rapi d resolution of the patient's symptoms.
