【摘要】：目的探讨腹部局限性透明血管型Castleman病(HV-CD)的MDCT特征性表现。方法回顾性分析经手术病理证实的11例腹部HV-CD患者术前CT平扫及动态增强资料。结果 11例中,9例病变位于腹膜后,2例位于肠系膜。CT平扫:11例均呈软组织密度肿块,平扫CT值为(46±4)HU,部分肿块内部可见斑片样、放射状低密度影及斑点样、树枝样钙化灶。2例局部边界不清。5例周围可见增大的淋巴结。4例周围腹膜局限性增厚。动态增强扫描:9例动脉期、门静脉期明显强化,CT值平均增加(80±14)HU,强化程度接近大动脉,延迟期强化程度退出;2例呈中度强化,且延迟期为著;1例动脉期边缘强化明显;病变内低密度区未强化;11例病变周围均可见供血及引流血管。结论腹部HV-CD的MDCT表现有一定的特征性,尤其是病变内的钙化及强化程度具有诊断价值。
[Abstract]:Objective to investigate the MDCT features of local transparent vascular Castleman's disease (HV-CD) in abdomen. Methods the data of preoperative CT plain scan and dynamic enhancement in 11 cases of abdominal HV-CD confirmed by operation and pathology were analyzed retrospectively. Results among the 11 cases, 9 cases were located behind the peritoneum, 2 cases were located in mesentery. CT plain scan showed soft tissue density mass in 11 cases. The CT value of plain scan was (46 卤4) HU,. Dendritic calcification was seen in 2 cases, local boundary was unclear in 2 cases, enlarged lymph nodes were seen in 5 cases, and local thickening of peripheral peritoneum was found in 4 cases. Dynamic contrast enhanced scan: in 9 cases, the enhancement of portal vein phase was obvious in 9 cases, the CT value increased (80 卤14) HU, enhancement degree was close to the great artery on average, the delayed phase enhancement degree withdrew, 2 cases showed moderate enhancement, and the delayed phase was the same. In 1 case, the margin of arterial phase was enhanced obviously, the low density area was not enhanced, and the blood supply and drainage vessels were found around the lesions in 11 cases. Conclusion the MDCT features of abdominal HV-CD are characteristic, especially the calcification and enhancement in the lesions.
