A Rare Case of Mucinous Cystadenoma of the Lung Mimicking Malignancy at 18F-FDG PET/CT

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.

“…In other cases, capture was intense in the solid portion of the lesion wall and significantly lower in the cystic part (26). There have also been cases of PMCA discovered using Pet-F-FDG/CT with high capture of 18F-FDG, mimicking lung cancer (30,31). In order to establish a preoperative histological diagnosis, some authors resorted to a CT guided fine-needle aspiration biopsy (32).…”
