Imaging of the submandibular glands can provide vital information about malignant neoplastic processes. One of these modalities, fluorine-18 fluorodeoxyglucose-positron-emission tomography/computed tomography (FDG-PET/CT), has become very important in the detection of malignancies because it provides functional and metabolic information as well as anatomic localization. However, there are several pitfalls associated with FDG-PET/CT in terms of salivary gland imaging. For example, a normal increase in the uptake of radiotracer might be mistaken for a neoplastic process. Other routine findings may include normal physiologic uptake in some structures, benign tumors and medical conditions, and iatrogenic abnormalities. We review a case in which compensatory hypertrophy of a submandibular gland was suspected to be a possible malignancy.
颌下腺成像可为恶性肿瘤性病变提供重要信息。其中一种检查方式，即氟-18氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（FDG-PET/CT），在恶性肿瘤检测中变得非常重要，因为它能提供功能和代谢信息以及解剖定位。然而，就唾液腺成像而言，FDG-PET/CT存在一些陷阱。例如，放射性示踪剂摄取的正常增加可能被误诊为肿瘤性病变。其他常见表现可能包括某些结构的正常生理性摄取、良性肿瘤和内科疾病以及医源性异常。我们回顾了一例疑似颌下腺代偿性肥大可能为恶性肿瘤的病例。
