Asymptomatic and Symptomatic Colloid Cysts of the Third Ventricle

Natural history of asymptomatic colloid cysts of the third ventricle.

OBJECT To determine the natural history of colloid cysts of the third ventricle in patients in whom the cysts were incidentally discovered, the authors retrospectively reviewed cases observed during the modern neuroimaging era (1974-1998). METHODS During this 25-year interval, 162 patients with colloid cysts were examined and cared for at our center. Sixty-eight patients (42%) were thought to...

Symptomatic colloid cysts in the third ventricle of monozygotic twins

In this case report we describe colloid cysts in the third ventricles of monozygotic twin sisters. They were 26 years old when their condition was discovered. One woman was admitted to us on an emergency basis, with signs of high intracranial pressure such as unconsciousness and extension posturing. Her sister was also brought to the hospital since she had a history of attacks of headache. They...

High risk of acute deterioration in patients harboring symptomatic colloid cysts of the third ventricle.

OBJECT Patients harboring colloid cysts of the third ventricle can present with acute neurological deterioration, or the first indication of the lesion may appear when the patient suddenly dies. The risk of such an occurrence in a patient already identified as harboring a colloid cyst is unknown. The goal of this study was to estimate the risk of acute deterioration in patients with colloid cys...

Endoscopic Treatment of Colloid Cysts of Third Ventricle: Study of Three Cases

Introduction: Colloid cyst of the third ventricle is a rare intracranial benign tumor. Traditionally, treatment is carried out by transcallosal or transcortical transventricular approach. Currently, the endoscopic treatment of these lesions is increasingly used. We reported our preliminary experience about three cases of colloid cysts treated by neuroendoscopy. Methods and Patients: We condu...
