Diagnosis of Inflammatory Pseudotumor of Liver by the Doppler and Ultrasonography / 中华超声影像学杂志

ABSTRACT

Ten patients with 12 inflammatory pseudotumor of the liver (IPL) lesions were routinely examined by gray scale uhrasonography(B-US),color Doppler (CD)and pulscd Doppler(PD). All of them in B-US were hypoechoic pattern with inhomogeneity,and one of them displayed helo-like,margin, suggesting malignant tumor. However, the irregular shape with calabash-like was found in 10 IPL lesions by B-US, being different from liver cancer.The color blood flow and arterial spectrum were detected by CD and PD in the margin 3 of 9 IPL lesions,and the resistant index was less than 0.5 in 2 of 3 IPL with Doppler signals, 6 of them were suggested to lack of blood supply, the manifistations of Doppler were consistent with pathology of IPL. Therefore, 8 lesions were considered to be benign lesions by Doppler US and the accuracy for the diagnosis of IPL was 56%(5/9)by using Doppler combined with B-US.
