Orthopnea is a severe dyspnea occurring at supine position. In addition to internal and pulmonary etiology, orthopnea occurs in patients with respiratory muscle weakness. Acute onset of orthopnea on the basis of bilateral phrenic nerve lesion is the most frequently seen in patients with neuralgic amyotrophy. Clinically, there is paradoxical breathing with prominent worsening after lying down, so that the patient is urged to immediately sit down. Chest radiography and chest sonography, are the most important auxiliary examinations, followed by motor nerve conduction studies of phrenic nerves and needle electromyography of diaphragm. The authors describe case reports of three patients with severe bilateral phrenic nerve lesions on the basis of neuralgic amyotrophy.
