A 71-year-old woman with a history of surgically treated bronchial atypical carcinoid underwent Ga DOTATATE PET/CT for restaging. Somatostatin receptor PET/CT revealed a focal area of mild radiopharmaceutical uptake corresponding to a thickening of the right choroid. No other areas of abnormal tracer uptake were detected in the rest of the body. Based on these PET/CT findings, the patient underwent examination of fundus oculi, MRI, and fluoroangiography, which confirmed the presence of a choroidal lesion interpreted as solitary choroidal metastasis of neuroendocrine tumor. Subsequently, the patient was referred for brachytherapy with radical intent.
一位 71 岁女性，既往有支气管不典型类癌手术史，行 Ga DOTATATE PET/CT 检查行肿瘤分期。生长抑素受体 PET/CT 显示右侧脉络膜有一处放射性摄取轻度增加，相应部位脉络膜增厚。全身其他部位未见异常示踪剂摄取。根据这些 PET/CT 结果，患者行眼底检查、MRI 和荧光血管造影，证实存在脉络膜病变，考虑为神经内分泌肿瘤的孤立性脉络膜转移。随后，患者行放射性近距离治疗。
