Abstract

The authors present two cases of meningiomas with unusual neuroradiological preoperative findings but with histological pictures of benign meningiomas. The first female patient has been submitted during childhood to radiation therapy for tinea capitis. At the age of 50 she was operated on for removal of a right frontal convexity meningioma. After two years, MRI control showed a left parietal parasagittal mass, the characteristics of which were completely different from the previously operated tumor. In fact, the lesion was hypointense in T1-weighted images and hyperintense in T2-weighted images. On CT scan it was hypodense without enhancement. At 54 years of age, the second mass was surgically removed and the histological picture was of meningothelial meningioma with microcystic elements. The following year a third meningioma was removed, but the radiological finding was similar to the first lesion. The follow-up is uneventful after nine years from the first operation. The second patient, a 55-year-old woman, experienced a left partial motor seizure followed by generalization. Enhanced CT scan showed a large right fronto-temporal polycystic tumor with mass effect and irregular margins, suggesting the diagnosis of malignant glioma. On the operation we found an extracerebral tumor, adherent to the dura of the pterion, to the lesser wing and convexity. The histopathological feature was of angioblastic meningioma. Misleading neuroradiological features and histological correlations are discussed.
