ABSTRACT

Fibrous hamartoma of infancy (FHI) is a rare benign subcutaneous tumor that presents in children younger than two years. The tumor mostly affects the trunk, axilla and upper extremities. Imaging findings of FHI that involve the buttocks have not been reported in the clinical literature. We reported the imaging features of a lesion in a 9-month-old infant who presented with a palpable mass on the buttocks. The imaging findings were evaluated after a review of previous studies.
