Unilateral diaphragmatic paralysis is often discovered incidentally in patients undergoing chest radiography for some other reason. Patients usually are asymptomatic at rest but may experience dyspnea upon exertion and may have a decrease in exercise performance. [12]

If the patient has an underlying lung disease, dyspnea may occur at rest.

Some patients may develop orthopnea, which is generally less intense than patients bilateral diaphragmatic paralysis.
