Postoperative cranial computed tomography scan revealed tumor removal with normal postoperative changes and persisting preexisting perilesional edema [Figure 2].
(a) Tumor tissue containing large cells seeming as fat-like proliferation with classic meningothelial neoplastic cells. Tumor cells have round nuclei and fat vacuoles in their cytoplasms (H and E, x40). (b) Tumor tissue showing the expression of epithelial membrane antigen (EMA, x40). (c) Tumor tissue showing positive staining with vimentin (Vimentin, x40). (d) Tumor tissue showing the expression of progesterone receptor (PR, x200)
