A 61-year-old woman was referred for further evaluation of an intracystic nodule in her left upper lung. Computed tomography( CT) showed a 15 mm nodule in a pulmonary cyst adjacent to aortic arch and mediastinum. Fluorodeoxyglucose-positron emission tomography (FDG-PET)-CT showed little uptake of FDG in the lesion. No abnormality was found in the bronchoscopy findings. On imaging findings, the possibility of pulmonary aspergilloma was considered, but the serological findings were inconsistent, and surgical resection of the lesion was performed for both diagnosis and treatment. The final pathohistological diagnosis was well differentiated liposarcoma. No adjuvant therapy was performed and the patient has been well without recurrence for 2 years after the surgery. We report a rare case of well differentiated liposarcoma of a lung mimicking pulmonary aspergilloma.
一名61岁女性因左上肺囊内结节接受进一步评估。计算机断层扫描（CT）显示在与主动脉弓和纵隔相邻的肺囊肿内有一个15毫米的结节。氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）-CT显示该病变中FDG摄取很少。支气管镜检查未发现异常。根据影像学表现，考虑为肺曲菌球，但血清学检查结果不一致，因此对该病变进行手术切除以明确诊断并进行治疗。最终病理组织学诊断为高分化脂肪肉瘤。未进行辅助治疗，患者术后2年情况良好，无复发。我们报告一例罕见的模仿肺曲菌球的高分化肺脂肪肉瘤病例。
