Is there room for stereotactic radiosurgery as an option for third ventricular colloid cysts in patients refusing surgery? A case report and some therapeutic considerations.

Lustgarten L - Surg Neurol Int (2015)

Bottom Line: Colloid cysts of the third ventricle are epithelium-lined mucus-filled cysts usually occurring in the anterosuperior third ventricle.They are benign, slow-growing lesions but with the risk of sudden death.The current case describes a patient presenting with hydrocephalus and a colloid cyst.

ABSTRACT

Background: Colloid cysts of the third ventricle are epithelium-lined mucus-filled cysts usually occurring in the anterosuperior third ventricle. They are benign, slow-growing lesions but with the risk of sudden death. Treatment alternatives for symptomatic cysts include stereotactic aspiration, microsurgical or endoscopic approaches, and shunts for hydrocephalus.

Case description: The current case describes a patient presenting with hydrocephalus and a colloid cyst. A ventriculoperitoneal shunt was placed as the patient refused a definitive surgical procedure for the removal of the cyst, and stereotactic radiosurgery was then performed.

Conclusions: Stereotactic radiosurgery may be a reasonable alternative with minimal risks in those patients harboring a third ventricle colloid cyst refusing a definitive surgical procedure for resection of the cyst.

Mentions: After thoroughly discussing with her the lack of published evidence in the literature, regarding any experience using stereotactic radiosurgery for colloid cysts, she decided to undergo Gamma knife radiosurgical treatment (Leksell Gammaknife Model 4c Elekta Systems) 3 months later. It prescribed 13 Gy to the 65% isodose line [Figure 2]. The procedure went uneventful, and she was discharged immediately with a recommended visit schedule.
