A young man with an atypical liver mass: Focal nodularhyperplasia

Abstract

With the increase in imaging methods, incidence of incidental masses has been increased. Focal nodular hyperplasia is the mostcommon benign liver mass after hepatic adenomas and is often diagnosed with typical images in contrast enhanced sectionalimaging methods. In atypical imaging, liver biopsy may be required for a definitive diagnosis. We present an atypical case thatwe diagnosed as focal nodular hyperplasia with clinical decision, although it does not show any typical radiologic and pathologicfindings.
