The colloid cyst is a benign lesion typically located in the third ventricle, near the foramina of Monro — a key region for cerebrospinal fluid circulation. Although it is a benign tumor, it can obstruct fluid flow and produce hydrocephalus, severe headaches, memory disturbances, visual alterations, and even serious neurological symptoms.
Our team specializes in ventricular endoscopic surgery, a minimally invasive technique that allows us to resect this type of lesion while avoiding extensive craniotomies and minimizing surgical trauma.
The clinical case we present is that of a patient with progressive headaches and episodes of intracranial hypertension. Studies showed a colloid cyst of the third ventricle associated with ventricular dilation. A complete endoscopic resection was performed through ventricular neuroendoscopy, and the patient progressed favorably, with resolution of symptoms and adequate ventricular circulation in subsequent follow-ups.
The surgery was carried out through a neuroendoscopic ventricular approach via a small incision and a millimeter-sized burr hole. Using high-definition endoscopic vision, the colloid cyst was identified, its capsule was opened, its content evacuated, and the cyst wall subsequently resected microsurgically.
This type of approach allows us to avoid extensive craniotomies, reduce brain tissue injury, achieve a faster postoperative recovery with less pain, and shorten hospitalization time.
