Colloid cyst of the third ventricle

Abstract

A colloid cyst is a malformation composed of an amorphous, gelatinous material surrounded by epithelial and connective tissue. It is typically located in the third ventricle, leading to signs of increased intracranial pressure and hydrocephalus. In this case report, we discuss a classic presentation of a patient presenting with a colloid cyst of the third ventricle. This includes the patient's symptoms before arriving at the emergency department and presentation upon arrival and during their hospital stay. We also discuss the diagnostic approach to colloid cysts, providing radiographic imaging to support the diagnosis. Finally, we discuss the approach to treatment of a colloid cyst, including temporizing measures to relieve symptoms and definitive measures for removal of the colloid cyst. The overall approach from diagnosis to management to definitive treatment of a colloid cyst requires an interdisciplinary approach but prompt recognition of the signs and symptoms in the ED can decrease both morbidity and mortality associated with this potentially fatal diagnosis.

Endoscopic resection of colloid cysts: Technical aspects and Surgical outcomes

“…Most of the other symptoms are mostly attributed to increased intracranial pressure due to CSF flow obstruction (21) . Acute hydrocephalus associated with disturbed conscious level can be the first presentation which prompt an emergency intervention (24) , 3 patients (11.1%) in this study presented with disturbed conscious level and hydrocephalus, EVD insertion on urgent basis was done with subsequent endoscopic resection of colloid cyst in the following day. Neuroimaging studies including CT scan and MRI usually describe it as a round lesion lying in the anterior superior part of the 3 rd ventricle with variable density and intensity according to viscosity of cyst contents (25,26) .…”

Giant Colloid Cyst: A Rare Etiology for Chronic Headache

“…Colloid cysts are typically slow-growing tumors that arise from remnants of the primitive neuroepithelium. They are usually found incidentally in neuroimaging studies or may present with nonspecific symptoms such as headache, dizziness, nausea, vomiting, or visual changes [2]. Rarely, they may present with acute neurological symptoms such as seizures, sudden onset of severe headaches, or syncope [3].…”

“…Colloid cysts are filled with a thick, viscous fluid that is rich in protein and cholesterol, and they are lined by a layer of the columnar or cuboidal epithelium [4]. The mechanism by which these cysts cause symptoms is related to the obstruction of the third ventricle, leading to increased intracranial pressure and hydrocephalus [2].…”

“…Although colloid cysts are usually small and benign, they can grow to large sizes and cause life-threatening complications, such as obstructive hydrocephalus. In this case report, we present a rare case of a giant colloid cyst in a patient with a chronic headache, highlighting the potential severity of this condition and the importance of early diagnosis and management [1][2].…”

“…A colloid cyst is a relatively rare type of benign brain tumor that can cause significant neurological symptoms. These cysts are composed of a gelatinous material known as colloid and typically occur in the third ventricle of the brain [2]. Although colloid cysts are usually small and benign, they can grow to large sizes and cause life-threatening complications, such as obstructive hydrocephalus.…”
