A 53-year-old woman with a choroidal hemangioma of the left eye treated with photodynamic therapy. The patient underwent secondary enucleation about seven years after the treatment because of vitreous hemorrhage. Axial (a) T2-weighted turbo spin-echo STIR and (b) fat-suppressed T1-weighted images show a lentiform intraocular mass along the postero-medial aspect of the globe (white arrows). Compared with the contralateral (normal) vitreous body, the lesion is isointense on T2-weighted image and slightly hyperintense on T1-weighted image. The vitreous body of the left eye is diffusely hypointense on T2-weighted and hyperintense on T1-weighted sequences because of extensive vitreous hemorrhage (asterisks). (c) Histological examination: low magnification showing a nodular, vascular mass protruding into the posterior chamber of the eye (H&E, original magnification ×25). (d) At higher magnification the mass was composed of numerous, dilated, cavernous vascular spaces lined by flattened endothelial cells and filled with red blood cells and fibrinoid material (H&E, original magnification ×100). The findings are consistent with choroidal hemangioma
