Monitoring of a hydroplasia nodular focal hepatic case for magnetic resonance with hepato-specific contrast medium.

Abstract

ABSTRACT
Focal nodular hyperplasia (FNH) is the most frequent benign liver tumor after hemangioma, it is caused by the hyperplastic response to a focal vascular anomaly. Most of the time asymptomatic is discovered incidentally. It occurs more frequently in young middle-aged women with a history of prolonged oral contraceptive intake. This type of neoformation has characteristic findings in different imaging methods. They usually tend to remain the same size and even involute for a long period under observation. We present the case of a patient with FNH, the diagnosis and monitoring was performed by magnetic resonance with hepatospecific contrast, it is a technique that allows observing its benign behavior, differentiating it from other types of liver lesions and avoids invasive procedures such as biopsy. After 2 years of diagnosis, the lesion remains without changes, demonstrating that the attitude towards a patient with FNH should be observant, since they have the potential for the spontaneous regression.
