Focal Hepatic Eosinophilic Infiltration in Contrast-Enhanced Ultrasonography with Sonazoid: A Case Report

ABSTRACT

Focal eosinophilic infiltration in the liver is often associated with various eosinophil-related conditions. Focal eosinophilic infiltration in the liver is often identified incidentally by radiologic examinations ordered for other reasons, and is usually visualized radiographically as small, ill-defined, oval or round nodules. Focal eosinophilic infiltration in the liver may sometimes mimic hepatic metastases in those patients who present with a history of malignancy. Here, we present two cases of contrast enhanced ultrasonography findings of focal hepatic eosinophilic infiltration using Sonazoid (perfluorobutane; Daiichi-Sankyo, GE, Tokyo, Japan).
