A 59-year-old woman with a history of both breast and lung cancer developed a new 1.5 cm solitary pulmonary nodule on computed tomography (CT) scan. The nodule had increased 18F-fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET) with a standard uptake value (SUV) of 3.4. A CT guided biopsy was performed, and Mycobacterium avium complex (MAC) was identified. PET scans have become an important part of the diagnosis, staging, and follow-up of cancer. Even in individuals at considerable risk for cancer with a solitary nodule demonstrating increased FDG uptake, further diagnostic evaluation and needle biopsy might receive consideration prior to surgical intervention.
一名有乳腺癌和肺癌病史的59岁女性在计算机断层扫描（CT）上发现了一个新的1.5厘米孤立性肺结节。该结节在正电子发射断层扫描（PET）上18F-氟脱氧葡萄糖（FDG）摄取增加，标准摄取值（SUV）为3.4。进行了CT引导下活检，鉴定为鸟分枝杆菌复合体（MAC）。PET扫描已成为癌症诊断、分期和随访的重要组成部分。即使是患癌风险相当高的个体，若有孤立性结节且FDG摄取增加，在手术干预前也可能会考虑进一步的诊断评估和穿刺活检。
