[1] Symptoms can include headache, vertigo, memory deficits, diplopia, behavioral disturbances, and in extreme cases, sudden death.

Patients with third-ventricular colloid cysts become symptomatic when the tumor enlarges rapidly, causing cerebrospinal fluid (CSF) obstruction, ventriculomegaly, and increased intracranial pressure.

In these cases, if the cyst stops growing, the patient can maintain a steady state between CSF production and absorption and may not require neurosurgical intervention.

The main management options are observation, craniotomy for microsurgical resection, neuroendoscopic removal, stereotactic drainage, and CSF diversion with bilateral ventriculoperitoneal shunting placement.

[8] Quality of life is found to be better following endoscopic excision than microsurgery, with cysts smaller than 18 mm showing better cognitive outcome.

[9] Another study found that ventriculomegaly may not be a contraindication for endoscopic removal, as the condition has comparable complication rates.

The surgery was successful in removing the cyst; the smaller retractor tube minimized resection injury.
