title: Ruptured teratoid tumor in the pineal region.
abstract: Distinctive plain X-ray and computer assisted tomography (CAT) findings led to the diagnosis in a case of teratoma in the pineal region and helped avoid invasive investigations. The demonstration by CAT of the location and size of the tumor as well as the presence of marked hydrocephalus directed the patient's therapy to ventriculoperitoneal shunting and radiation.
