Terson's syndrome after endoscopic colloid cyst removal: case report and a review of reported complications.

The authors report on a patient with Terson's syndrome after endoscopic colloid cyst resection of the third ventricle. This never reported complication in neuroendoscopy is explained by an increased intracranial pressure due to rinsing. Increased rinsing was needed to prevent the ventricles from collapsing. A free outflow channel and rinsing pace should always be matters of concern during neuroendoscopic procedures. Complications in neuroendoscopic colloid cyst removal are reviewed from the literature.
