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. (authors)
