A 57-year-old man admitted to our hospital with a pulmonary nodule detected by chest X-ray. Chest X-ray and chest computed tomography (CT) showed a solitary nodule with a spiculation in the right lower lobe (S8), 17 x 15 mm in size. His laboratory findings were almost within normal ranges. Positron emission tomography (PET) showed positive detection correspond to the nodule (SUV max: 5.76). Pathological diagnosis by CT-guided lung biopsy was suspected of gastrointestinal stromal tumor (GIST). Further examination of digestive organs revealed no abnormalities. The enlargement of the nodule was noted 2 weeks later, 23 x 18 mm in size. We couldn't rule out a malignant tumor and performed partial resection of the right lower lobe. Pathological diagnosis by intraoperative frozen section was "inflammatory myofibroblastic tumor (IMT), no malignancy". The patient is alive without any signs of recurrence for 4 months postoperatively.
一名57岁男性因胸部X线检查发现肺部结节入住我院。胸部X线和胸部计算机断层扫描（CT）显示右肺下叶（S8）有一个孤立性结节，有毛刺征，大小为17×15mm。他的实验室检查结果几乎在正常范围内。正电子发射断层扫描（PET）显示与该结节对应的检测呈阳性（最大标准化摄取值：5.76）。CT引导下肺活检的病理诊断怀疑为胃肠道间质瘤（GIST）。进一步检查消化器官未发现异常。2周后发现结节增大，大小为23×18mm。我们不能排除恶性肿瘤的可能，遂对右下叶进行了部分切除。术中冰冻切片的病理诊断为“炎性肌纤维母细胞瘤（IMT），无恶性”。患者术后4个月存活，无任何复发迹象。
