Magnetic resonance imaging brain [Figure 1] done revealed a 4.1 cm x 4.3 cm x 3.2 cm intensely enhancing extra-axial lesion with central necrosis in the right CP angle cistern.
(a) Spindle cell tumor with hypo- and hypercellular areas suggestive of schwannoma. Verocay bodies (thin arrow) are seen (H and E, x20). (b) Tumor is negative for epithelial membrane antigen

Histopathology revealed that the anterior part of the tumor [Figure 2a and b] was composed of sheets and interlacing fascicles of cells along with Verocay bodies suggestive of a spindle cell tumor (schwannoma). Both the tumors in our case were confirmed with immunohistochemistry [Figure 2b and 3b].
(a) Moderately cellular tumor with oval to spindle cells arranged in sheets and whorls suggestive of a meningioma. Psammoma bodies (bold arrow) are also seen (H and E, x20). (b) Tumor is positive to epithelial membrane antigen

The lateral part of the tumor [Figure 3a and b] was composed of a moderately cellular tumor with sheets and whorls of spindle to oval cells and few psammoma bodies suggestive of meningioma. Both the tumors in our case were confirmed with immunohistochemistry [Figure 2b and 3b].
