Mucoepidermoid carcinomas in the bronchial tree are extremely rare tumors. Such tumors are classified into low-grade and high-grade on the basis of histological criteria. Fluorine-18-fluorodeoxyglucose positron emission tomography (F-18 FDG PET) is a useful technique for the evaluation of pulmonary lesions; however, to our knowledge, F-18 FDG PET findings in mucoepidermoid carcinoma of the bronchus have been described in only a few cases. Identifiable focal F-18 FDG uptake has been reported in high-grade mucoepidermoid carcinoma, but it is unclear whether F-18 FDG accumulates in low-grade mucoepidermoid carcinoma. Here, we present the case of a 37-year-old woman, with pathologically proven low-grade mucoepidermoid carcinoma, who underwent high-resolution computed tomography (CT) and F-18 FDG PET/CT before treatment.
支气管树中的黏液表皮样癌是极为罕见的肿瘤。此类肿瘤根据组织学标准分为低级别和高级别。氟-18-氟脱氧葡萄糖正电子发射断层扫描（F-18 FDG PET）是评估肺部病变的一种有用技术；然而，据我们所知，仅在少数病例中描述过支气管黏液表皮样癌的F-18 FDG PET表现。已有报道称高级别黏液表皮样癌中可识别出局灶性F-18 FDG摄取，但尚不清楚F-18 FDG是否在低级别黏液表皮样癌中蓄积。在此，我们报告一例37岁女性患者，经病理证实为低级别黏液表皮样癌，在治疗前接受了高分辨率计算机断层扫描（CT）和F-18 FDG PET/CT检查。
