Pulmonary inflammatory myofibroblastic tumor is a rare disease. Computed tomography in a 54-year-old woman showed a mass compressing the segmental bronchus of the left lung. Bronchoscopy indicated a mesenchymal tumor, hamartoma, or inflammatory myofibroblastic tumor. Because an inflammatory myofibroblastic tumor can potentially clog the segmental bronchus, we performed a left upper division segmentectomy. Pathologic examination revealed an inflammatory myofibroblastic tumor. In most cases, preoperative diagnosis is difficult because of the varied radiologic manifestations, and it can also be difficult to distinguish from malignancy in small tissue samples.
肺炎性肌纤维母细胞瘤是一种罕见疾病。一名54岁女性的计算机断层扫描显示有一个肿块压迫左肺的段支气管。支气管镜检查提示为间叶性肿瘤、错构瘤或炎性肌纤维母细胞瘤。由于炎性肌纤维母细胞瘤可能会堵塞段支气管，我们实施了左上肺叶段切除术。病理检查显示为炎性肌纤维母细胞瘤。在大多数情况下，由于放射学表现多样，术前诊断困难，而且在小组织样本中也难以与恶性肿瘤区分开来。
