The use of FDG PET/CT in the assessment of oncologic disease is becoming increasingly widespread. The advent of PET/CT however presents some additional challenges; recent reports have emphasized the need to detect incidental findings which can confer additional health risks. We report a case of a pulmonary embolus with pulmonary infarct secondary to a metastatic right atrial mass on a background of squamous cell carcinoma of the neck that demonstrated findings on both the PET and CT portions of the examination. The significance of standardized uptake value (SUV) in the differential diagnosis of chest lesions is discussed. This report highlights the possible co-existence of non-metastatic, but potentially life threatening abnormalities that may be present on the CT portion of such studies.
氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（FDG PET/CT）在肿瘤疾病评估中的应用越来越广泛。然而，PET/CT的出现带来了一些额外的挑战；最近的报告强调了检测可能带来额外健康风险的偶然发现的必要性。我们报告了一例在颈部鳞状细胞癌背景下，由右心房转移瘤继发肺栓塞伴肺梗死的病例，该病例在PET和CT检查部分均有表现。讨论了标准化摄取值（SUV）在胸部病变鉴别诊断中的意义。本报告强调了在此类检查的CT部分可能存在非转移性但潜在危及生命的异常情况。
