Colloid cysts constitute 1% or fewer of intracranial tumor and arise from primitive cells during fetal development. They are usually located in the anterior (front) portion of the third ventricle, resting against the hypothalamus, where they may block the outflow pathways for the cerebrospinal fluid and cause hydrocephalus (water on the brain).
Treatment options may include endoscopic surgery or an open craniotomy via the corpus callosum of the brain.
Eddie was in his usual state of health until February 5, 2005, when he was besieged by a sudden and intense frontal headache.
Concerned that he might have a leaking aneurysm, his family doctor ordered a CT scan.
Rather than a hemorrhage, the scan showed a colloid cyst of the 3rd ventricle, causing obstructive hydrocephalus.
Eddie was referred to Dr. Reid, who advised him that he was at risk for sudden death due to
the hydrocephalus, and recommended urgent surgery.
A craniotomy was performed using microsurgical technique to expose and remove the colloid cyst, relieving the obstruction and allowing the spinal fluid to return to normal.
After one night in the neurosurgical ICU and two nights in a regular room, Eddie went home and has returned to his daily routine.
