Overview

Overview

Most common symptoms seen in pneumomediastinum are sudden onset of pain in the chest and subcutaneous emphysema. In most cases, pain follows the signs of causative or underlying pathology such as exacerbation of asthma. Spontaneous pneumomediastinum in most cases presents without any symptoms. Besides chest pain, other frequent symptoms are cough, dyspnea or pain in the neck. Most specific finding on physical exam is Hamman’s sign, which is a mediastinal crunch or click present on auscultation over the cardiac apex and the left sternal border synchronous with the heartbeat.
