We report a case of bilateral metastatic melanoma to the extraocular muscles that simulated thyroid eye disease. A 71-year-old man presented with bilateral painless axial proptosis, lid retraction and left gaze restriction. Orbital CT scan demonstrated enlargement of the extraocular muscles with tendon sparing, consistent with thyroid eye disease. However, thyroid function tests and antithyroid antibodies were normal. Systemic review including orbital MRI scan determined the correct diagnosis of metastatic melanoma to the orbit. Metastatic melanoma to the orbit can simulate thyroid eye disease.
我们报告一例双侧转移性黑色素瘤累及眼外肌,临床表现类似甲状腺眼病。一名71岁男性患者,出现双侧无痛性轴向眼球突出、眼睑退缩及左眼凝视受限。眼眶CT扫描显示眼外肌增粗,肌腱未受累,符合甲状腺眼病表现。然而,甲状腺功能检查及抗甲状腺抗体均正常。包括眼眶MRI扫描在内的全身检查确定该患者为眼眶转移性黑色素瘤。眼眶转移性黑色素瘤可表现类似甲状腺眼病。
