An abnormal lung shadow was detected in a 39-year-old woman at physical examination and she was followed-up carefully at a nearby hospital. After 5 years follow-up, the patient was referred to our hospital for further examination of the abnormal shadow. A chest computed tomography(CT) scan revealed a 12 mm well-circumscribed nodular shadow in the right lower lobe. A benign tumor such as a hamartoma was suspected preoperatively;video-assisted thoracic surgery was performed for both diagnosis and treatment. Partial resection of the right lower lobe was performed and the tumor was diagnosed as an intrapulmonary solitary fibrous tumor (SFT). No malignant features, such as nuclear atypia, necrosis, or mitotic activity, were identified. Careful observation will be necessary, because a few SFTs have a propensity to recur or metastasize. The post-operative course was uneventful and there has been no recurrence at 7 years after surgery.
一名39岁女性在体检时发现肺部有异常阴影，随后在附近医院接受了仔细随访。经过5年的随访，患者因该异常阴影被转诊至我院进行进一步检查。胸部计算机断层扫描（CT）显示右下叶有一个边界清晰的12毫米结节状阴影。术前怀疑为错构瘤等良性肿瘤；遂行电视辅助胸腔镜手术以明确诊断并进行治疗。对右下叶进行了部分切除，肿瘤被诊断为肺内孤立性纤维瘤（SFT）。未发现核异型性、坏死或有丝分裂活性等恶性特征。由于少数SFT有复发或转移倾向，因此有必要进行密切观察。术后过程顺利，术后7年未出现复发。
