Transscleral Invasion of Solitary Fibrous Tumor

A 19-year-old man without remarkable medical history presented with a severe vision loss in his left eye. A, Ophthalmoscopy showed a hemispherical grey mass beneath the retina, accompanied by hemorrhage. B, Magnetic resonance imaging demonstrated a well-demarcated mass penetrating the wall of the eyeball and extended into the orbit cavity, with heterogenous isointense on T2-weighted imaging. Intraorbital biopsy reported a diagnosis of solitary fibrous tumor. After 3 years, the left eye developed exophthalmos without evidence of metastasis. The patient underwent enucleation. C, Hematoxylin & eosin stain showed ovoid or spindle nuclei in a "patternless" pattern, interspersed branching vessels, and amianthoid fibers.
