肝脏炎性假瘤12例DSA影像分析

目的探讨肝脏炎性假瘤的DSA影像特点及其诊断、鉴别诊断价值。方法回顾性研究我科2002年5月至2007年3月12例术后病理证实的肝脏炎性假瘤患者的DSA造影表现,并将相关影像资料进行对照分析。结果10例患者为肝脏单发占位病变,2例多发;动脉晚期病灶开始显影,在实质期及门静脉期,7例病灶周边染色明显,呈环状,中央区对比剂充填较淡,5例病灶不均匀染色。结论DSA是肝脏类性假瘤诊断和鉴别诊断最有用的方法之一。

Analysis of DSA for inflammatory pseudotumor of the liver(analysis of 12 cases)

Objective To evaluate the diagnostic and differential diagnotic values of DSA features for inflammatory pseudotumor of the liver(IPL). Methods An retrospectively comparative analysis of 12 hepatic inflammatory pseudotumors confirmed surgicopathologically from May 2002 to March 2007 with DSA features and correlative imaging data were carried out. Results 10 cases consisted of only 1 lesion and other 2 cases with multiple lesions were opacified initially at the late arterial phase,with prominent peripheral ring-like staining at portovenous and parenchymal phases and less dense opacification in the central region; furthermore heterogenous staining occurred in 5 cases. Conclusions DSA is probable the most appropriate method for the diagnosis and differential diagnosis of hepatic inflammatory pesudotumor.
