Endoscopic Approach for Management of Colloid Cyst

Background: Third ventricular colloid cysts are uncommon tumors that make up 15 to 20% of intraventricular and 0.2 2% intracranial tumors. Colloid benign tumors, but they may grow until block the foramen Monro, which might result in a fatal accident. Aim Work: Assessment efficacy endoscopic excision(total or subtotal) cyst relation size Patients Methods: The research was prospectively carried out at neurosurgery department Al-Azhar university hospitals, from January 2019 December 2021. Included fifteen patients with were operated by endoscope for their mass hydrocephalus. Results: This study showed male-to-female ratio 1.5:1, median age 32.87 years. Headache commonest presenting symptom affecting 93.3% patients. Most (93.3%) hydrocephalic time presentation. mean diameter 20.53 mm. usually hyperdense CT scans (60%), hyperintense T1W MRI (60%) variable T2W appearance. Conclusion: T1 MRI. They require surgical resection if larger than 1 cm causing symptoms avoid rapid neurological deterioration unexpected death brought on CSF flow occlusion. has no significant impact cyst.
