Fibrolipomatous hamartoma of the median nerve are usually located distally in the forearm and may have characteristic features on MR imaging. Here we report a patient with an extensive fibrolipomatous hamartoma at an unusual location proximally in the arm, where a preoperative MR imaging was pathognomonic and diagnosis was verified by an incisional biopsy. We suggest that MRI should be performe...

Rhabdomyomatous mesenchymal hamartoma (RMH) is a benign, rare entity with approximately 70 cases reported since the 1980’s [1]. This was first described in 1986 as a striated muscle hamartoma [1]. It has also been reported as congenital midline hamartoma and hamartoma of cutaneous adnexa and mesenchyme [1]. RMH most often presents as a solitary lesion on the head or neck of an infant [2].
