腹部Castleman病影像学诊断

Radiologic diagnosis of abdominal Castleman's disease

目的:探讨腹部Castleman病的影像学表现。材料与方法:腹部Castleman病4例,女3例,男1例。均行X线、超声、CT检查并经手术及病理证实。结果:病灶为单发,肾形或椭圆形,均有完整的包膜,可见条状、绒毛状或珊瑚状钙化;超声以低回声为主,可见点条状强回声,后方伴声影;CT平扫示软组织肿块,边缘清楚,周围有点条状影,增强肿块与周围点、条状影呈明显均匀强化。结论:Castleman病的影像学表现缺乏特征性;肿块不侵及邻近组织和器官,见到肿块内出现条状、树枝样钙化应想到本病的可能。

Objective:To demonstrate imaging features of abdominal Castleman's disease.Materials and Methods:Four cases of abdominal Castleman's disease were reported.Three cases were female and one case was male.X-ray,ultrasonography and CT were performed,all cases underwent surgical operation and were proved by pathology.Results:Lesion was solitary,eliptical in shape,all were well capsulated,streak,flock-like or coral like calcification can be seen within the lesion.On sonography the lesion was mainly hypoechogenicity with dot or streak-like increased echogenicity accompanied by acoustic shadow.On CT,the lesion appeared as a soft tissue mass with well defined margin surrounded by dot or streak-like shadow,usually markedly enhanced after contrast scanning.Conclusion:Although there is no characteristic signs but if there is streak-like,usually the mass does not invade the adjacent tissue and organs,branching calcifications within the lesion then Castleman's disease should be considered.
