Radiographic diagnostic evaluation and surgical treatment of multiple cerebellar, brain stem, and spinal cord hemangioblastomas.

Multiple hemangioblastomas of the central nervous system present a greater challenge in their diagnosis and treatment than do single hemangioblastomas of the cerebellar hemisphere. Improved radiographic techniques of tomographic vertebral angiography and computed axial tomography (CT) are of considerable value in the diagnosis of multiple cerebellar, brain stem, and spinal cord hemangioblastomas. Microsurgical techniques now allow for total operative removal of many of these lesions. A case report is presented to emphasize the radiographic diagnostic evaluation as well as the microsurgical technique for removal of multiple central nervous system hemangioblastomas.
