A 69-year-old male patient presented with multiple lung nodules revealed by chest-computed tomography (CT) during a preoperative examination for an appendiceal tumor. The nodule diameters ranged from 2-10 mm without either pleural thickening or effusions. A fluorine-18-labeled fluorodeoxyglucose (F-FDG)-positron emission tomography (PET)/CT scan showed a high FDG uptake in the appendiceal tumor, but almost normal standardized uptake values in the bilateral lung nodules. A CT-guided biopsy led to a diagnosis of pulmonary epithelioid hemangioendothelioma, a rare vascular tumor with a radiological presentation similar to that of a metastatic lung tumor. The present case is the first to describe successful treatment using a CT-guided biopsy instead of more conventional methods.
一名69岁男性患者在阑尾肿瘤术前检查时，胸部计算机断层扫描（CT）发现多个肺结节。结节直径为2 - 10毫米，无胸膜增厚或胸腔积液。氟-18标记的氟脱氧葡萄糖（F-FDG）正电子发射断层扫描（PET）/CT显示阑尾肿瘤有高FDG摄取，但双侧肺结节的标准化摄取值几乎正常。CT引导下活检诊断为肺上皮样血管内皮瘤，这是一种罕见的血管肿瘤，其影像学表现与肺转移瘤相似。本病例是首例描述使用CT引导活检而非更传统方法成功治疗的案例。
