Contrast-enhancing hepatic eosinophilic abscess during the hepatic arterial phase: a mimic of hepatocellular carcinoma.

Abstract

Our objective was to review CT, MR, angiographic, and sonographic images obtained in patients with histopathologically proven contrast-enhancing hepatic eosinophilic abscesses during the hepatic arterial phase. On CT, MR, and angiographic images, eosinophilic abscess in the liver can show contrast enhancement during the hepatic arterial phase. If patients have peripheral hypereosinophilia or are at low risk for hepatocellular carcinoma or hepatic metastasis, those with small arterial-enhancing hepatic nodules need further preoperative evaluation, such as a sonographically guided biopsy.
