{Abstract}: <B>BACKGROUND: </B>Focal nodular hyperplasia is a common nonmalignant liver mass. This nonvascular lesion is an uncommon mass in children, especially those with no predisposing factors, namely radiation, chemotherapy, and hematopoietic stem cell therapy. Exophytic growth of the lesion further than the liver margins is not common and can complicate the diagnosis of the lesion. This report observes a focal nodular hyperplasia as a pedunculated lesion in a healthy child.<BR><B>METHODS: </B>We describe a 9-year-old healthy Persian child who was born following in vitro fertilization complaining of abdominal pain lasting for months and palpitation. Employing ultrasound and computed tomography, a mass was detected in the right upper quadrant compatible with focal nodular hyperplasia imaging features. The child underwent surgery and the mass was resected.<BR><B>CONCLUSIONS: </B>Diagnosing focal nodular hyperplasia, especially pedunculated form can be challenging, although magnetic resonance imaging with scintigraphy is nearly 100% sensitive and specific. Thus, a biopsy may be needed to rule out malignancies in some cases. Deterministic treatment in patients with suspicious mass, remarkable growth of lesion in serial examination, and persistent symptoms, such as pain, is resection, which can be done open or laparoscopic.
