目的：探讨Ｋａｐｏｓｉ＇ｓ肉瘤的影像学表现，以期提高对本病的影像学认识。材料与方法：２例经病理证实的Ｋａｐｏｓｉ＇ｓ肉瘤，均伴有皮肤病损。１例摄腕部Ｘ线片，１例作肝脏超声和ＣＴ扫描，并均有治疗前、后对比图像。结果：１例右腕骨骨质吸收、稀疏，骨小梁模糊，关节面毛糙，腕间关节及部分掌腕关节间隙增宽；１例超声及ＣＴ均发现肝右叶有２ｃｍ以上低密度灶，经动态增强扫描示病灶位肝内门脉分支旁，早期强化不显，经延迟后病灶有所强化并示低密度区缩小。２例经化、放疗后病变均示修复改变。结论：Ｋａｐｏｓｉ＇ｓ肉瘤可累及内脏、骨骼，无论并发ＡＩＤＳ与否，病理改变是相似的。但影像学表现缺乏特征性，确诊有赖病理诊断
Objective: To investigate the imaging findings of Kaposi’s sarcoma in order to improve the imaging knowledge of this disease. Materials and Methods: Two cases of pathologically confirmed Kaposi’s sarcoma were associated with skin lesions. In one case, radiographs were taken from the wrist, and one case was used for hepatic sonography and CT scan. Both had pre- and post-treatment contrast images. Results: In one case, the bone resorption and sparsity of the right carpal bone, the trabecular bone was blurred, the surface of the joint was rough, the space between the wrist and the palmar joints of the wrist was widened, and 1 case of low density lesion with more than 2 cm was found in the right lobe. The dynamic enhanced scan showed that the lesion was located beside the intrahepatic portal vein branch, and early enhancement was insignificant. After the delay, the lesion was strengthened and showed that the low density area was reduced. Two cases of lesions after chemotherapy and radiotherapy showed repair and change. Conclusion: Kaposi’s sarcoma can affect internal organs and bones. Whether or not AIDS is complicated, the pathological changes are similar. However, the lack of imaging features, diagnosis depends on pathological diagnosis
