title: 59-year old female with suprasellar mass.
abstract: Intracranial capillary hemangiomas are extremely rare. Only 14 histologically proven cases have been reported in the literature. A 59-year-old-female presented with a severe headache for 3 weeks. Brain MRI revealed a homogeneous contrast enhancing round mass lesion in the pituitary stalk and infundibular recess. We performed endoscopic biopsy. In the operative field, a reddish, well-circumscribed mass from the infundibular recess protruded into the third ventricle and it was separated from the optic chiasm. The tumor appeared a highly vascular. Histopathological examination demonstrated an aggregation of thin-walled capillaries, consistent with capillary hemangioma.
