Diagnosis and surgical treatment of brainstem hemangioblastomas

Two types of BSHs can be identified. Patients with cystic IBS type could obtain excellent outcome after operations. Patients with giant or large solid BSHs remain a challenge to neurosurgeons. A combined strategy of preoperative embolization, mild hypothermia with or without hypotension, microsurgical technique, and intensive perioperative management are mandatory for removal of these kinds of tumors with acceptable morbidity and mortality.
