Abstract: Cerebral cavernous malformations occur in 0.5% of the population. They consist of thin-walled vessels and can be found as congenital or sporadic lesions. Most of them are asymptomatic, however, due to their anatomical features blood leakage into the surrounding tissue can cause severe neurological symptoms. Although risk of bleeding is low, symptomatic lesions should be treated, with microsurgical resection being the therapy of choice for surgically accessible cavernomas. Intraventricular cavernous malformations are a rare subtype, and due to their anatomical localization, they are eligible for endoscopic surgery. However, there are only a few reports on endoscopic resection of intraventricular cavernomas to be found in the literature. We report the case of a 48-year-old woman who suffers from multiple cerebral cavernous malformations. Since the first diagnosis, several of these cavernomas had been removed in open microsurgical interventions. Most recently, a new lesion arose intraventricularly, adjacent to the ependymal wall of the right lateral ventricle. In follow-up, cranial MR imaging microbleeding and an increasing size were detected. Eventually, the lesion was endoscopically removed. Presurgery the patient suffered from right-sided sensibility loss and gait disturbances as a consequence of prior surgeries. Postsurgery, no new neurological symptoms could be found. We here present MR images and intraoperative pictures as well as a short video of the resection itself. In our opinion, endoscopic resection of intraventricular cavernomas should be considered in selected cases.
