Giant colloid cyst of the third ventricle: challenges in management

Abstract

Background: Giant colloid cysts (size > 3 cm) are very rare with only few reported cases in the literature. Case presentation: We report a case of 44 year female who presented with features of raised intracranial pressure, memory and gait disturbances. CT and MR imaging showed a large colloid cyst at foramen of Monro leading to obstructive hydrocephalus. The patient underwent right interhemispheric transcallosal-transforaminal approach and complete excision of the cyst. Conclusions: For a large size of colloid cyst complete surgical excision is recommended. However deep midline location, proximity to the vital structures and giant size of the lesions make surrounding vital structures vulnerable for injury.

Acute hydrocephalus caused by colloid cyst of third ventricle: A case report

“…External ventricular drainage was kept within hours to prevent further hydrocephalus and extension of infarct. Management options for large and symptomatic CCs include stereotactic aspiration, endoscopic fenestration, and resection, open surgical resection, and microsurgery [ 4 , 6 , 8 ]…”

Surgical outcome of intraventricular tumors of the brain

“…Even smaller lesions have been reported to be associated with sudden death. 5 Epidermoid cyst of the lateral ventricles are relatively rare. Probably the first such recorded intracranial lesion was seen in the lateral ventricle in 1745, when Verratus described an intra-ventricular mass containing hair.…”
