epithelioid hemangioendothelioma (ehe) is a rare neoplasm of vascular origin which arises preferentially in soft tissue and bone, and rarely in the liver. its vascular nature is confirmed by positive staining for factor viii-related antigen and other endothelial cell markers (cd31, cd34) in addition to the pathologic characteristics of well-developed basal lamina, pinocytotic vesicles, and, mor...

we report two cases of focal nodular hyperplasia in patients following gadoxetic acid (gd-eob-dtpa)-enhanced magnetic resonance imaging confirmed with histopathology. these cases showed an atypical pattern during the delayed-hepatobiliary phase after the injection of gadoxetic acid. one case showed a total defect, and the other showed a peripheral ring-like enhancement without a visible central...

Liver ultrasound was prospectively evaluated in 104 subjects who underwent liver biopsy, including 24 patients without evidence of liver disease (controls), and 80 with a broad spectrum of liver pathology. Ultrasonography was very specific (100%) and moderately sensitive (70%) in the detection of liver pathology, and hepatic neoplasms, steatosis, and fibrosis were detected by ultrasound in 80%,...
