Abstract

As a result of advances in imaging technique, eosinophilic liver infiltrations (ELIs) are frequently found in clinical practice. ELIs are often found not with clinical symptoms but with incidental routine imaging checkups. ELIs appear on ultrasonography as diverse features such as round hyperechoic nodule mimicking hemangioma or small iso to hypoechoic nodule in subcapsular area. ELIs appear on computed tomography scans as multiple, hypoattenuated, small, round lesions that has blurred margins and are mainly discerned during the portal phase. ELI is associated with several common conditions that include peripheral eosinophilia, such as parasitic infections, allergic diseases, and drug hypersensitivities. Among the parasite infection, toxocariasis is the most common cause of ELIs in Korea. Although ELI is usually a benign condition commonly caused by parasitic infections, hypereosinophilic syndrome, allergic disease and malignancies are one of the causes of ELIs. Therefore, physicians should evaluate the cause of ELIs.
