Savardekar","Abha Verma","Vinayak Narayan","Anita Mahadevan","Malla Bhaskar Rao"],"abstract":"Background: Meningiomas are common tumors, constituting about 20% of all primary brain tumors, with lipomatous meningioma being a rare subtype that represents approximately 0.3% of meningiomas. This histological variant is characterized by lipid accumulation within meningothelial cells and is classified as a metaplastic meningioma (WHO Grade 1). The clinical features and prognosis of lipomatous meningiomas are similar to other WHO Grade 1 meningiomas. Summary: We present a case of a 44-year-old female with long-standing generalized tonic-clonic seizures, where MRI revealed a well-demarcated, extra-axial, dural-based lesion with hyperintensity on T1- and T2-weighted images. Histopathological examination confirmed the diagnosis of lipomatous meningioma, showing large lobules of mature adipose tissue and characteristic whorls of meningothelial cells. The patient underwent successful surgical excision and remained asymptomatic at one-year follow-up. Conclusion: This report emphasizes the distinct MRI characteristics of lipomatous meningioma and their correlation with histopathological findings. Recognizing these imaging features may aid in the preoperative diagnosis of this uncommon tumor, which is often diagnosed histopathologically.
