The reversed halo sign (RHS) has been associated with various pulmonary diseases. We report a rare case of pulmonary mucosa-associated lymphoid tissue lymphoma forming a RHS from a ground-glass opacity (GGO). A 73-year-old man was followed-up for the GGO on his computed tomography images, which gradually extended peripherally. During the fourth year of follow-up, the GGO significantly evolved into a well-demarcated, oval lesion, with interlobular and intralobular septal thickenings, and multiple air spaces were surrounded by a well-defined thin consolidative rim, called the RHS. A pathologic study of the specimen via transbronchoscopic biopsy revealed pulmonary mucosa-associated lymphoid tissue lymphoma.
反晕征（RHS）与多种肺部疾病相关。我们报告了一例罕见的由磨玻璃影（GGO）形成反晕征的肺黏膜相关淋巴组织淋巴瘤病例。一名73岁男性因计算机断层扫描图像上的GGO接受随访，该GGO逐渐向周边扩展。在随访的第四年，GGO显著演变为边界清晰的椭圆形病变，伴有小叶间和小叶内间隔增厚，多个气腔被边界清晰的薄实变环包围，称为反晕征。经支气管活检对标本进行病理研究，结果显示为肺黏膜相关淋巴组织淋巴瘤。
