Unilateral diaphragmatic paralysis (UDP) is usually found incidentally in those who underwent chest radiography for some other reason. Often patients are asymptomatic at rest but may have breathlessness upon exertion and have a decrease in exercise capacity. Dyspnea at rest may occur if the patient has an underlying lung disease. Few develop orthopnea, which is less intense than patients with bilateral diaphragmatic paralysis (DP). Others present with positional snoring and progressive orthopnea misinterpreted it as sleep-disordered breathing. Here we present a 54-year-old male who presented late with sleep-disordered breathing and was diagnosed to have diaphragmatic palsy postcoronary artery bypass graft.
