Bilateral median neuropathy and growth hormone use: a case report.

A male elite bodybuilder suffered bilateral median nerve neuropathy during a self-administered course of growth hormone (GH). Nerve conduction velocities revealed bilateral median neuropathy consistent with carpal tunnel syndrome (CTS). This is the first case of GH-induced CTS occurring in an athlete. Contrary to earlier studies, this report demonstrates that GH-induced CTS is not an age-related phenomenon and alerts physicians to include GH abuse as a possible etiology of median neuropathy in athletes.
