Pulmonary adenofibroma (PAF) is a rare benign tumor. Computed tomography (CT) imaging of PAF show well-defined, homogeneous and solitary nodules. To the best of our knowledge, there is no report of PAF presenting with central liquefaction necrosis on CT images. The present study reports the case of a 70-year-old man who was hospitalized due to an inguinal hernia without respiratory symptoms. Chest CT scan revealed a tumor (~6.5x5.5x4.4 cm) in the lower lobe of the left lung, characterized by uneven density and unclear boundary with the pleura. Contrast-enhanced scan revealed that the lesion was slightly enhanced and liquefaction necrosis appeared in its center. Wedge resection was performed using video-assisted thoracic surgery. Histopathological and immunohistochemical examination confirmed the diagnosis of PAF.
肺腺纤维瘤（PAF）是一种罕见的良性肿瘤。PAF的计算机断层扫描（CT）成像显示边界清晰、均匀的孤立结节。据我们所知，尚无CT图像上PAF出现中央液化坏死的报道。本研究报告了一名70岁男性因腹股沟疝住院，无呼吸道症状。胸部CT扫描显示左肺下叶有一个肿瘤（约6.5×5.5×4.4 cm），其特征为密度不均匀，与胸膜边界不清。增强扫描显示病变轻度强化，中央出现液化坏死。采用电视辅助胸腔镜手术进行楔形切除术。组织病理学和免疫组化检查确诊为PAF。
