Lipome géant de la main : présentation d’un cas clinique et revue de la littérature

Median Nerve Compression in Carpal Tunnel Caused by a Giant Lipoma

“…This compression produces an atypical clinical presentation that can mimic carpal tunnel syndrome. In the literature, “giant lipoma” is defined as a lesion that measures more than 5 cm [3]. Using a case report to support our claims, we provide information about lipomas in the hand and the diagnostics traps that they constitute.…”

“…Lipomas of the hand principally occur in individuals between 50 and 60 years of age [3, 4]. Patients usually report progressive development of a soft, mobile, and painless tumefaction on one of their hands.…”

“…Its clinical expression is identified by the topography of the compression: carpal tunnel syndrome in the case of median nerve compression [3, 5], hypoesthesia of the half pulp in the case of digital collateral nerve compression [4], and ulnar hypoesthesia in the case of Guyon's canal compression [6]. Other localizations are more anecdotal: compression of the superficial sensory branch of the radial nerve in the anatomical snuffbox [2] or compression of the posterior interosseous nerve [7].…”

“…The size of 5 cm is the classical cutoff for definition of giant lipoma [3, 5, 8, 21, 22]. This definition is based on the infrequency of lipomas exceeding this size.…”

Clinics in diagnostic imaging (169)

“…(7) Another rare presentation is acute neuropathy due to nerve compression by interstitial haemorrhage. (9) Lipomas larger than 5 cm are called giant lipomas, (10) such as in the case presented. Lipomas usually grow at a very slow rate and the aetiology of rapid growth into giant lipomas is debatable.…”
