Bilateral medial pectoral neuropathy in a weight lifter.
Weight lifting has occasionally been associated with focal neuropathies of unknown cause. We describe a case of progressive bilateral medial pectoral neuropathy in a body builder. Whereas the medial pectoral nerve passes through pectoralis minor to reach the pectoralis major, the lateral pectoral nerve has no such intramuscular course. We postulate that weight lifting and concomitant pectoralis minor hypertrophy in our patient produced intramuscular entrapment of the medial pectoral nerves.
