Giant cell arteritis (GCA) may cause visually devastating optic neuropathy. In atypical cases, diagnosis of optic neuropathy can be delayed. We present 2 such atypical cases and demonstrate that contrast-enhanced orbital magnetic resonance imaging may be a valuable tool in patient evaluation and aid in the diagnosis of GCA.
巨细胞动脉炎（GCA）可引起严重的视觉神经病变。在不典型病例中，视神经病变的诊断可能会被延误。我们报告了 2 例不典型病例，并证实增强眶磁共振成像可能是评估患者的有价值的工具，并有助于 GCA 的诊断。
