Lipofibromatous hamartoma of the median nerve - A case report.

Lipofibromatous hamartoma (LFH) is a rare benign slow growing fibrofatty tumour. It comprises a neurogenic mass of non-inflamed peripheral nerve bundles surrounded and separated by mature fat. LFH has a tendency for the median nerve; however, involvement of the brachial plexus, ulnar, radial, peroneal and plantar nerves has also been described. Patients typically experience pain, with or without sensory and motor deficits. The diagnosis of LFH is highly supported by imaging findings. Ultrasound is increasingly being recognised as a useful tool in aiding diagnosis.
