A giant colloid cyst of the third ventricle: A case report

Abstract

Colloid cysts of the third ventricle constitute approximately 1% of all intracranial tumors, and they represent the most prevalent form of neuro-epithelial cysts. They are rare, benign cystic lesions with a wide clinical spectrum, but headache is usually dominant. A large cyst may appear in conjunction with an intracranial hypertension syndrome. Additionally, they can induce obstructive hydrocephalus, resulting in rapid acute neurological decline and, in some cases, sudden death. In this study, our aim is to present the clinical manifestations and radiological features of a giant recurrent colloid cyst of the third ventricle by presenting a case of a 55-year-old female patient, reporting a 2-month history of progressively worsening intracranial hypertension syndrome. The focus is specifically placed on the importance of prompt diagnosis and management to prevent potential life-threatening complications. Minimally invasive modalities, like stereotactic cyst aspiration and neuroendoscopy, are now the preferred techniques of management but present a higher rate of recurrence. Awareness of this condition for early diagnosis and management is fundamental for a better prognosis and patient care.
