Abstract
Medullary cavernous malformations are the rarest subtype of brainstem cavernous malformation and are associated with a high degree of morbidity. Selection of surgical candidates is critical, and cases are most favorable when the cavernous malformation abuts the surface of the brainstem. This limits the amount of native tissue transgressed during the resection. This patient had a large cavernous malformation within the caudal medulla eccentric. A right-sided paramedian far-lateral approach was used to access the brainstem. The cavernous malformation was readily apparent along the medullary surface and was dissected away in its entirety. Postoperative imaging confirmed complete resection. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary.
