Abstract

We describe a rare case of pulmonary mucinous cystadenoma (PMCA) detected F-FDG PET/CT and mimicking a malignancy. A 60-year-old female patient underwent F-FDG PET/CT for metabolic characterization of a left pulmonary nodule which showed increased F-FDG uptake (SUVmax = 3.7). Based on this PET/CT finding, the patient underwent a cuneiform resection of the left pulmonary nodule. Histology demonstrated the presence of a PMCA. In our case, F-FDG PET/CT has been useful in detecting this rare pulmonary tumor.

摘要

我们描述了一例罕见的肺黏液性囊腺瘤（PMCA），该病例通过 F-FDG PET/CT 检测并模拟恶性肿瘤。一名 60 岁女性患者因左肺结节代谢特征行 F-FDG PET/CT 检查，结果显示 F-FDG 摄取增加（SUVmax = 3.7）。基于该 PET/CT 发现，患者行左肺结节楔形切除术。组织学显示存在 PMCA。在我们的病例中，FDG PET/CT 有助于检测这种罕见的肺肿瘤。
