Lipofibromatous hamartoma (LFH) is a rare fibrofatty tumor of adipocytes within peripheral nerves, affecting mainly children. It typically presents as a palpable mass surrounding the nerves of the upper limbs, causing pain and neurological deficits in the affected nerve distribution. We report the case of a child with a 2-years presentation of a mass in the right wrist associated with pain and paresthesia, who underwent investigation with magnetic resonance imaging (MR I). It showed thickening of the median nerve with spaghetti-like appearance associated with lipomatous tissue in a coaxial cable-like pattern, both features characteristic of LFH. This case illustrates the importance of MRI in the differential diagnosis of limb masses in the pediatric population.
