title: Vitamin A induced benign intracranial hypertension.
abstract: A case of benign intracranial hypertension due to prolonged administration of a low dose of Vitamin A is described in a young male investigated as a brain tumor suspect. Computerized axial tomography showed small and symmetrical lateral ventricles which was consistent with the diagnosis. The syndrome of benign intracranial hypertension and its relationship to chronic Vitamin A toxicity is discussed.
