摘　　要：目的:探讨胸内Castleman病的CT、MRI影像学表现。方法:回顾性分析经手术后病理证实的6例胸内Castle-man病的CT、MRI表现。结果:6例胸内Castleman病均为局限型;透明细胞型5例,浆细胞型1例。病灶位于中纵隔2例,其中1例同时累及前纵隔;肺门1例;后纵隔3例。CT表现为纵隔及肺门圆形或卵圆形软组织肿块,边缘清晰、光整伴分叶状1例;病灶密度均匀4例,不均匀2例,出现斑点状钙化2例,不规则坏死1例为浆细胞型;2例行MRI检查的表现T1WI像中纵隔病灶为稍高信号,右肺门为高信号,T2WI像为不均匀高信号;增强CT与MRI表现相似,病灶显著强化,CT值增加40HU左右,均匀强化4例,不均匀强化2例,在T1WI增强上呈均匀高信号。结论:Castleman病有一定的CT和MRI影像学特征,具有较高的诊断价值。Objective： To explore the CT and MRI appearances of thoracic castleman＇s disease. Methods： The appearances of CT and MRI of thoracic castleman＇s disease （n = 6） confirmed by operative pathology were analyzed retrospectively. Results：2 lesions were in middle mediasfinum, 1 lesion in hilum pulmonis, 3 lesions in posterior mediasfinum. The thoracic castleman＇s disease （n = 6） including hyaline-vascular type （n = 5） and plasma cell type （n = 1）. On CT the lesions were round or oval soft-tissue mass, distinct and trim margin with smooth and uniform density （n = 4）, unhomogeneous density （n = 2）, spot calcification （n = 2）, abnormity necrosis （n = 1 ）. The lesions were slightly hypefintense in middle mediasfinum, hypefintense in right hilum pulmonis on T1WI images; unhomogeneously hyperitense on T2WI. Homogeneous enhancement （ n = 4）, unhomogeneous enhancement （ n = 2） and homogeneous hypefintense on T1WI were apparent during contrast on CT and MRI; all lesions were obvious enhancement and 40HU increased. Conclusian： The CT and MRI have important value in diagnosis of castleman＇ s disease.
