Calcifying Aponeurotic Fibroma of the Dorsum of the Foot: Radiographic and Magnetic Resonance Imaging Findings in a Four-Year-Old Boy

Calcifying aponeurotic fibroma (caf) is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet, in children and adolescents. due to its infiltrative nature, this tumor can mimic malignancy on preoperative magnetic resonance imaging (mri) and has a predilection for local recurrence. there are very few reports in the literature that describe features of caf on mri, especially those arising in the foot. we present an unusual case of a caf affecting the dorsum of the foot in a four-year-old boy.
