Intraventricular craniopharyngioma: a long-term follow-up of six cases

Intraventricular craniopharyngiomas are rare tumours. They are wholly within the third ventricle and can be distinguished from suprasellar lesions which extend into the third ventricle by the presence of an intact floor of the third ventricle. They are attached to the wall of the third ventricle to a variable extent, most commonly in the region of the tuber cinereum. The long-term follow-up on six cases treated by one of the authors is presented. Headache and visual disturbance were the most common presenting features but, unlike the more common suprasellar lesions, symptomatic endocrine disturbances were not a common presenting feature. Total surgical removal can cause hypothalamic damage and the resulting morbidity can be serious and sometimes life-threatening. Subtotal removal followed by radiotherapy is probably the treatment of choice for these lesions.
