The Third Ventricle Colloid Cyst Spontaneous Rupture Phenomenon: A Rare Clinical Observation and World Literature Review

Colloid cysts of the third ventricle are rare congenital benign lesions that can cause acute occlusion of CSF pathways with the risk of a fatal outcome. Up to 6% of colloid cysts are asymptomatic, incidental findings. Colloid cysts tend to slowly increase in size over a long period of time. Management of patients with colloid cysts of the third ventricle depends on clinical and radiological findings. Spontaneous shrinkage (rupture) of the colloidal cyst is an extremely rare phenomenon, described only in 8 cases worldwide.
