Ciliated muconodular papillary tumor (CMPT) is a rare benign lung tumor characterized by ciliated columnar cells, mucous cells, and basal cells. Herein, we report a case of CMPT with 11 years of preoperative follow-up, depicting the natural course of the tumor and changes in computed tomography (CT) findings. A 39-year-old man had a 5-mm solid pulmonary nodule in the right lower lobe that had slowly grown and transformed into a thin-walled cavitary lesion. Right lower lobe lobectomy was performed and the tumor was confirmed to be a CMPT. Although it is difficult to diagnose CMPT with CT findings alone, CMPT should be considered as a possible diagnosis when a slowly growing nodule undergoes cavitary changes.
纤毛黏液结节乳头状肿瘤（Ciliated muconodular papillary tumor，CMPT）是一种罕见的良性肺肿瘤，其特征是存在纤毛柱状细胞、黏液细胞和基底细胞。本文报告了一例 CMPT 患者，其术前随访时间长达 11 年，描述了肿瘤的自然病程和 CT 表现的变化。一名 39 岁男性右肺下叶有 5mm 大小的实性肺结节，该结节缓慢生长并转变为薄壁空洞性病变。行右肺下叶肺叶切除术，术后病理证实为 CMPT。虽然单凭 CT 表现难以诊断 CMPT，但当缓慢生长的结节发生空洞性改变时，应考虑 CMPT 作为可能的诊断。
