摘要

68Ga-DOTATATE对神经内分泌肿瘤并不是完全特异性的，广泛的良恶性肿瘤在PET扫描上可能显示68Ga-DOTATATE的高摄取。脾脏错构瘤是一种罕见的良性实性脾脏病变，由多种正常脾脏结构混合而成。在此，我们报告了一位49岁的女性，她接受了68Ga-DOTATATE PET/CT扫描，以确定十二指肠神经内分泌肿瘤的完整分期，偶然发现脾脏病变有强烈的放射性示踪剂摄取，手术病理显示为脾脏错构瘤。

False-positive Uptake in Splenic Hamartoma on 68Ga-DOTATATE PET/CT.

68Ga-DOTATATE is not completely specific for neuroendocrine tumors, and a wide range of benign and malignant tumors may reveal high uptake of 68Ga-DOTATATE on PET scan. Spleen hamartoma is a rare benign solid lesion of the spleen, composed of a mixture of normal splenic structures. Here we present a case of a 49-year-old woman who underwent a 68Ga-DOTATATE PET/CT scan for complete staging of a duodenal neuroendocrine tumor, and it incidentally demonstrated intense radiotracer uptake in a splenic lesion, with surgical pathology demonstrating a splenic hamartoma.
