BackgroundWe report on the case of a patient with meningioma that was correctly identified through biopsy.Case DescriptionA 69-year-old woman presented with slight headache and was then examined at our hospital. Neurologic and physical examinations found no abnormality. Magnetic resonance imaging demonstrated a well-enhanced huge, dural-based, and plaque-like mass extending throughout the parietooccipital convexity and the posterior fossa. Tumors pressed the adjacent brain cortex while extending along the Virchow-Robin space. A CT scan also showed hyperostosis on the parietooccipital bone. Angiography demonstrated a vascular blush that appeared to be of a tumor-like shape. A biopsy was performed to confirm the diagnosis. The histologic findings demonstrated meningothelial meningioma with infiltration into the Virchow-Robin space.ConclusionsMany radiographic patterns of meningioma have been reported, but the present case is quite rare. The radiographic and pathologic findings in our patient are discussed.
