MeSH Terms

Fig. 1 Clinical, radiological, and pathological images of the patient. (A) Nine cardinal photographs of the patient show limitation in elevation (−2) and depression (−2) in the right eye. (B) Orbital magnetic resonance imaging revealed an enhancing mass in the right retrobulbar area involving the inferior rectus muscle and abutting the medial rectus muscle. The mass measured 1.2 × 1.4 × 0.9 cm and was isointense with the muscle in the T1-weighted image and hypointense in the T2-weighted image. (C) Eyeball sonography revealed a hypoechoic mass (asterisk) in the right inferior intraconal space without definite vascularity on the color Doppler image. (D) Biopsy of the mass revealed fibroskeletal tissue without mitoses, nuclear hyperchromasia, nuclear pleomorphism, or necrosis (H&E, ×100).
