Sclerosing pneumocytoma (SP) of the lung is a rare benign neoplasm. Here, we describe an unusual presentation of SP with a wax-and-wane pattern of growth in a 47-year-old woman. Tumor diameter decreased over a 3-year follow-up period and then increased on serial follow-up computed tomography scans. The mass showed high signal intensity on both T1- and T2-weighted chest magnetic resonance imaging (MRI) and early enhancement with a plateau on dynamic MRI. We speculate that intratumoral bleeding and resorption processes accounted for the changes in tumor size.
肺硬化性肺细胞瘤(SP)是一种罕见的良性肿瘤。在此,我们描述了一名47岁女性的SP不寻常表现,其具有大小变化的生长模式。在3年的随访期内肿瘤直径减小,而后在系列随访计算机断层扫描中增大。该肿块在T1加权和T2加权胸部磁共振成像(MRI)上均显示高信号强度,在动态MRI上早期强化并呈平台期表现。我们推测肿瘤内出血和吸收过程导致了肿瘤大小的变化。
