ABSTRACT

Isolated rupture of the pectoralis minor tendon is extremely rare and has been reported 3 times in 4 pa-tients. This article describes the first case of an isolated spontaneous pectoralis minor tendon tear in an end-stage renal disease (ESRD) patient undergoing long-term hemodialysis and with a previous history of bilat-eral rupture of the quadriceps tendons.He presented with left anterior shoulderand chest wall pain with direct tenderness on palpation over the coracoid. Magnetic resonance imaging revealed an isolated tear of the pectoralis minor tendon with an intact pectoralis major tendon. The patient returned to full activities after conservative management. Although rare, the diagnosis of pectoralis minor tendon rupture should be considered in ESRD patients who present with anterior shoulder pain in the absence of an antecendent trauma.
