The preferred treatment for intracranial hemangioblastomas is surgical resection with or without preoperative embolization, however, embolization remains controversial due to risks such as distal tip entrapment, vascular injury during navigation, and embolic agent migration.A 54-year-old woman was admitted for surgical resection and preoperative embolization of a cerebellar hemangioblastoma. Although experience using Onyx with detachable and nondetachable tip microcatheters has been well reported in a variety of clinical circumstances, we describe the first case of a presurgical embolization of an intra-axial tumor using a second-generation detachable-tip microcatheter and a nonadhesive liquid embolic agent. Following the procedure, a nearly complete angiographic obliteration was achieved, as well as a successful subsequent surgical resection.Preoperative embolization with detachable-tip microcatheters and liquid embolic agents should be taken into consideration when assessing patients with hemangioblastomas of the posterior fossa due to the reduced risks of cardiac arrest, hemorrhage, and death.
