[show abstract][hide abstract] ABSTRACT: Pituicytomas are rare tumors. Previously reported pituicytomas all presented with signs and symptoms relating to mass effect or endocrinological dysfunction. We report a 47 year old man who presented with sudden, severe headache and was found to have a hemorrhagic suprasellar mass with hemorrhage into the third ventricle. A mass arising from the pituitary stalk was found at surgery, and thorough pathological analysis revealed a pituicytoma. Pituicytoma should be considered in the differential diagnosis of a hemorrhagic suprasellar mass.
