Case in brief
A healthy child under 5 years presented with a gradually enlarging abdominal mass and early satiety. Imaging revealed classical features of focal nodular hyperplasia (FNH) in the left hepatic lobe. Due to the lesion's size and symptoms, a left lateral segmentectomy was performed, and histopathology confirmed FNH. The child had an uneventful recovery and remains well on follow-up.
Diagnostic / clinical pearl
Focal nodular hyperplasia can present as a significant abdominal mass in children, necessitating careful imaging and consideration of benign hepatic lesions in the differential diagnosis.
Why it matters
This case underscores the rarity of benign liver tumors like FNH in children, particularly in the context of predominantly malignant liver tumors in this age group.
