Case contributed by Dr MohammadTaghi Niknejad

Presentation

Right upper quadrant pain.

Patient Data

Age: 30-year-old
Gender: Female
Modality: CT

A large mass is seen at left hepatic lobe with bright contrast enhancement on arterial phase. The central scar of the lesion remain low attenuation on early phases. The scar demonstrate mild enhancement on delayed phase, but the lesion's density itself goes back to the background liver (isodense) on delayed phase. 

Case Discussion:

The CT findings in a 29 Y/O female are consistent with focal nodular hyperplasia (Histologically proven).

FNH is a benign tumour-like mass of the liver, second only to haemangiomas in frequency and most frequently found in young to middle aged adults, with a strong female predilection.
