A 56-year-old woman was initially diagnosed with optic neuritis. However, several "red flags" were present: older age at presentation, no multiple sclerosis suspicious findings on MRI, and negative oligoclonal bands. 68Ga-DOTATATE PET/CT confirmed the differential diagnosis of an optic sheath meningioma. Our case stresses the value of the somatostatin receptor ligand PET/CT in patients with suspected optic neuritis if the diagnostic workup does not support immune-mediated pathogenesis.
一名56岁女性最初被诊断为视神经炎。然而，存在几个“警示信号”：就诊时年龄较大、MRI上无多发性硬化可疑表现以及寡克隆带阴性。68Ga-DOTATATE PET/CT证实了视神经鞘膜瘤的鉴别诊断。我们的病例强调了在诊断检查不支持免疫介导发病机制的疑似视神经炎患者中，生长抑素受体配体PET/CT的价值。
