A 47-year-old female diagnosed with well-differentiated papillary thyroid carcinoma was referred to our center for a Iodine whole body scintigraphy as follow-up. The patient had been previously treated with total thyroidectomy and ablative dose of 175mCi I three years ago. Diagnostic I scan showed a zone of radioiodine uptake in posterior aspect of the left upper quadrant of the abdomen. Spiral abdominal and pelvic CT scan showed an enhancing solid mass in superior aspect of the left adrenal gland, which was in favor of metastasis to the lymph node or an adrenal tumor. A biopsy was performed from the lesion. Histological examination of the surgical specimen was consistent with adrenocortical adenoma. Even though rare, adrenocortical adenoma should be included in the potential causes of false-positive results of radioiodine scans.
一名47岁被诊断为高分化乳头状甲状腺癌的女性被转诊至我们中心进行碘全身闪烁扫描作为随访。该患者三年前曾接受甲状腺全切术及175mCi碘的消融剂量治疗。诊断性碘扫描显示在左上腹后方有一个放射性碘摄取区域。螺旋腹部和盆腔CT扫描显示左肾上腺上方有一个强化实性肿块，这提示可能是淋巴结转移或肾上腺肿瘤。对该病变进行了活检。手术标本的组织学检查结果与肾上腺皮质腺瘤一致。尽管罕见，但肾上腺皮质腺瘤应被列入放射性碘扫描假阳性结果的潜在原因之中。
