    Preoperative sagittal (A and B) and axial (C) T1-weighted MR images after contrast administration document the presence of a large vermian tumor extending toward the pineal region. The mass, compressing the fourth ventricle and brainstem, shows an irregular enhancement after gadolinium administration, and large vascular structures supplying the lesion are evident. Preembolization angiography (D) documented the vascular blush of the hemangioblastoma, whereas postembolization angiography (E) demonstrates a satisfactory devascularization of the mass. An early postembolization CT scan (F) shows the intratumoral hemorrhagic swelling with a marked mass effect on the brainstem.
