Abstract:
Objective To study the CT characteristics of inflammatory pseudotumor of the liver(IPL).Methods 16-slice spiral CT findings of IPL in 16 cases were analysed retrospectively.The CT values of IPLs and the liver tissue surrounding the lesions were measured on plain and contrast-enhanced CT scans.Results Totally 18 lesions in 16 cases were detected by CT,most of them(16 lesions) located in the right lobes of liver.The lesions appeared as low-density,round or round-like,or irregularity in sharp.Dynamic enhanced CT scan showed the lesions no or slight enhancement in arterial phase,slight to moderate enhancement in portal vein phase.A part of the lesions showed ring enhancement surrounding the lesions,nodular or fiber stripped enhancement in the center of lesions,and the branches of the portal vein passesed through the lesions.In enhanced degree of the lesions,there was not statistical difference in arterial phase compared with plain CT scans,but there were statistical differences in portal-venous phase compared with plain scan and arterial phase.In the liver around the lesion,the enhanced degree had statistical difference in artery phase and portal-vein phase compared with plain CT scans.Conclusion Dynamic enhanced CT scan shows that IPL is of hypovascularity,it's of characteristic in the portal-venous phase and delayed phase.
