A preoperative brain CT scan (Fig. 1) revealed a right medial temporal small high density and brain MRI with Gd. Fig. 2 shows a well-defined 4 x 4 centimeter solid mass of right cavernous sinus with bright enhancing. Histopathologic study shows a highly vascular tissue with a predominant capillary portion. Fig. 3, H&E x 40). Between small vessels, numerous vacuolated stromal cells with foamy cytoplasm can be seen, containing lipids and hyper-chromatic pleomorphic nuclei (Fig. 4, H&E x 200). Finally, a postoperative MRI with Gd (Fig. 5), after 4 months, shows an enhancing remnant of tumor on right cavernous sinus.
