A 58-year-old male presented with malignant fibrous histiocytoma originating from the lateral wall of the orbit, manifesting as left exophthalmos and diplopia on left lateral gaze. Magnetic resonance (MR) imaging demonstrated the tumor extending into the left orbit and under the temporalis muscle. The tumor was isointense with muscle on T1-weighted MR images and was surrounded by a low-intensity rim, which was proved to be the capsule after histological examination. The tumor was completely removed after detaching the lateral orbital rim and zygomatic arch using the dismasking flap method. He underwent one course of CYVADIC chemotherapy and has demonstrated no recurrence for 1 year and 6 months postoperatively.
一名58岁男性因起源于眶外侧壁的恶性纤维组织细胞瘤就诊，表现为左眼眼球突出及左侧凝视时复视。磁共振（MR）成像显示肿瘤延伸至左侧眼眶及颞肌下方。在T1加权MR图像上，肿瘤与肌肉呈等信号，周围有低信号环，组织学检查证实为包膜。采用揭盖皮瓣法分离眶外侧缘和颧弓后，肿瘤被完整切除。患者接受了一个疗程的CYVADIC化疗，术后1年6个月无复发。
