Compressive Lipoma of the Hand Causing Carpal Tunnel Syndrome

Aims: We report the case of a patient presenting with paresthesia in the median nerve territory following compression by a palmar lipoma evoking a carpal tunnel syndrome. The aim of this work is to review the epidemiological, diagnostic and therapeutic aspects of this pathology.

Presentation of Case: We present the case of a 40-year-old female patient who presented paresthesia in the territory of the median nerve, the clinical and paraclinical examinations showed the presence of a lipoma of the middle palmar region of the right hand at the origin of a compression of the branches of division of the median nerve; The resection of the lipoma and the neurolysis of the interdigital nerves of the median nerve have allowed a good evolution

Discussion: Lipoma of the hand is a very rare localization that can lead to nerve compression and can mimic the symptoms of carpal tunnel. The diagnosis is facilitated by ultrasound and magnetic resonance imaging (MRI).

Conclusion: Compression of the median nerve by a lipoma is a very rare cause. The removal of the lipoma and the neurolysis of the median nerve gives excellent results.
