title: Lipomatous meningioma: a study of five cases with brief review of literature.
abstract: Lipomatous meningiomas are an uncommon subtype of meningiomas. In the present report, the clinical characteristics, neuroimaing and pathological features of 5 patients (4 males, 1 female; age range, 17-45 years; mean age, 35.2 years) with lipomatous meningioma were analyzed. The neuro-pathological reevaluation of lipomatous meningioma involved assessment of histological features proposed by the current WHO classification. The presence or absence of high whorls, fascicles, solid growth, glial invasion, necrosis and nuclear pleomorphism was assessed. The most common presenting symptom was seizures. Location of tumor was frontal (3 cases), parietal (1 case) and fronto-temporal (1 case). All cases showed radiological features of conventional meningioma. Complete excision of tumor along with involved dura was performed in all the patients. Three tumors were meningothelial and 2 were transitional. Tumoral lipid content was variable from 10% to 30%. In addition, there were microcystic features (2 cases) and psammoma bodies (1 case). No recurrence was noted in any of our cases till the last follow-up. Lipomatous meningioma represents a rare distinctive type of meningioma, with a good prognosis with complete removal.
