| Abstract | Purpose: Complete resection of the tumor nodule(mural nodule or solid portion of the tumor) is the essential goal of surgical treatment for hemangioblastoma. The purpose of this study was to classify the morphologic types of intracranial hemangioblastoma on MRI and to compare the location and contour oftumor nodule on MRlwiththoseon angiography. Materials and Methods : The MRI findings of 34 lesions(38 lesions if 4 spinal cord lesions were included) in 26 patients(17 males and 9 females , range of age, 18-67 years, mean, 39 years) with surgically and histopathologically proved intracranial hemangioblastomas were reviewed. Seventeen patients underwent CT scanning in a short interva l. Contrast-enahnced T1-weighted imaging pa tterns of hemangioblastoma were classified according to Ho’ s morphologic types . The location and contour of tumor nodule were compared between MRI and angiography in 15 patients(24Iesions) . Results: By location , cerebellar hemispherewas predominated(55%). followed by cerebellar vermis(26%). supratentorial region(5%). and medulla oblongata (3%). Spinal cord lesions(11%) were seen in 3 patients of 5von Hippel-lindau diseases . The frequency of morphologic types was as follows; Type 1 (purelycystic). 3%, Type 2(mural noduleL 50%, Type 3(cyst with wall enhancement). 3%, Type 4 (cystic nodule). 15%, Type 5(solid with internal cyst). 9%, and Type 6(solid). 20%. AII tumor nodules(33 lesions) enhanced intensely with intravenous contrast material on MRI. of which 24lesions(in 15 patients) revealed hypervascular masses fed by pial arteries on angiography. They were superficial and abutted pia mater partiallyor in large portion on both MRI and angiography. Conclusion: Over 70% of intracranial hemangioblastomas had a surrounding cyst , and superficia l. pial -based location and number of the tumor nodules on MRI was correlated well with those on angiography. MRI is the examination of choice for preoperative evaluation of intracranial hemangioblastoma. |
