AIM Colloid cysts are uncommon lesions, which most commonly occur in the fourth through seventh decade. The authors hereby report a series of colloid cysts in the pediatric age group. MATERIAL AND METHODS A retrospective study was conducted on all patients of colloid cyst that underwent surgery at our institute over a period of seven years (2005 to 2011). Patients above the age of 20 were exc...

Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a ...

Colloid cysts are benign intracranial lesions, that account only 0.2-2% of intracranial lesions, mostly localized in the roof of the third ventricle. Although the cysts are histological benign, they sustain significant neurological presentation or death due to cerebrospinal fluid (CSF) obstruction and acute hydrocephalus. Cavum septi pellucidi, another pathology which can cause similar results,...

Purpose: The aim of this study was to investigate the feasibility and effectiveness of endoscopic neurosurgery for patients with third ventricular colloid cysts without ventriculomegaly. Methods: Seventy-one patients with third ventricular colloid cysts were identified and recruited to this study. Eighteen of these patients did not have concomitant hydrocephalus and underwent primary endoscopic...

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...

Immunohistochemical characterization of 14 cases of intracranial cysts was performed. Among these 14 cases, five different types of cysts were represented; Rathke's cleft cyst (4 cases), neurenteric cyst (2 cases), colloid cyst (1 case), choroidal epithelial cyst (2 cases) and arachnoid cyst (5 cases). Immunohistochemical evaluation utilized antibodies to glial fibrillary acidic protein (GFAP),...

BACKGROUND Surgical approaches to colloid cysts of the third ventricle have evolved over time. In recent years, endoscopy has been recognized as an effective alternative to open surgery. The disadvantage of endoscopic treatment is the difficulty in controlling the adhesion of the cyst to the roof of the third ventricle and in obtaining complete removal of the cyst. OBJECTIVE To design and car...

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...

Colloid cysts are relatively rare intracranial lesions located in the rostral aspect of the third ventricle. They may produce acute hydrocephalus, brain herniation, and lead to death. Although the clinical and imaging features of colloid cysts are well known, their etiology and the factors responsible for their imaging features continue to be a subject of debate. We present the imaging-patholog...
