PAROXYSMAL HEADACHE CAUSED BY COLLOID CYST OF THE 3RD VENTRICLE - CASE-REPORT AND REVIEW OF THE LITERATURE

Colloid cysts of the third ventricle are benign tumors that may cause brief, severe headache and, rarely, death. We present a patient with f requent, episodic, brief, severe headaches of 2 weeks' duration who su ddenly became obtunded. We reviewed the literature on the symptomatolo gy of colloid cysts and conclude that any patient with less than a 1-y ear history suggestive of a third ventricular colloid cyst causing bri ef, severe headaches should be aggressively investigated.
