Treatment of acute haemorrhage of pituitary tumours.

Sudden headache, visual loss, and mental change developed in three patients with unsuspected pituitary tumours. In each case stereotaxic transnasal cannulation of the intrasellar mass demonstrated a liquid haematoma under moderate pressure which could be easily aspirated. Restoration of vision and relief from neurological disturbances was prompt. Radiation therapy was then administered to prevent recurrence.
