Orbital myositis is a rare manifestation of systemic lupus erythematosus (SLE). Herein, we report a case of orbital myositis in a patient with SLE, along with a literature review. A 45-year-old female patient presented with pain in the right eye, chemosis, proptosis, and limited abduction. Computed tomography of her orbits revealed thickening of her right lateral rectus muscle. She had no other systemic symptoms. There was no elevation in the biomarkers of inflammation or disease activity. She was treated with high-dose steroids, and her symptoms resolved rapidly. It is important to maintain a high index of suspicion for orbital myositis in patients with SLE even when there are no systemic disease activities, such that early treatment can be initiated. It is also important to rule out other mimickers such as orbital cellulitis and thyroid eye disease.
眼眶肌炎是系统性红斑狼疮（SLE）的一种罕见表现。在此，我们报告一例SLE患者的眼眶肌炎病例，并进行文献综述。一名45岁女性患者出现右眼疼痛、结膜水肿、眼球突出及外展受限。眼眶计算机断层扫描显示其右侧外直肌增厚。她没有其他全身症状。炎症或疾病活动的生物标志物没有升高。她接受了大剂量类固醇治疗，症状迅速缓解。即使在没有全身疾病活动的情况下，对SLE患者的眼眶肌炎保持高度怀疑指数也很重要，以便能够尽早开始治疗。排除其他类似疾病如眼眶蜂窝织炎和甲状腺眼病也很重要。
