Original Report

Targetlike Appearance of Pseudotumors in Segment IV of the Liver on Sonography

OBJECTIVE. The purpose of this study is to report a new sonographic appearance of hepatic pseudotumors. These lesions had a targetlike appearance but were caused by spared areas in fatty liver.

CONCLUSION. Although representing a frequent pattern in metastases and mycotic abscesses, a central hyperechoic core encircled by a hypoechoic halo has not yet been reported in relation to pseudotumors. Whereas multifocal target lesions in the liver suggest metastases or mycotic abscesses, an isolated target lesion in the fourth hepatic segment requires a differential diagnostic approach and a pseudotumor should be suspected because of its clinical relevance.
