Spontaneous Pneumomediastinum, Is it very rare??Created by:
Pneumomediastinum (Mediastinal emphysema) is a consequence of air leakage from the bronchial tree or lungs into the mediatinal structures, with possible upward extension into the neck. While traumatic chest or oesophageal injuries are the well-known causes of secondary pneumomediastinum, the first case of spontaneous pneumomediastinum(also known as Hamman's Syndrome) was described only in 1939 by Louis Hamman. It is considered rare, with approximate frequencies of 1 per 10,000 admissions (or fewer) reported. Clinical features of spontaneous pneumomediastinum include chest pain, dyspnoea, dysphagia, neck pain, subcutaneous emphysem, and Hamman's crunch. It usually will follow a benign self limitng course. It is vital to exclude the secondary/traumatic cause of pneumomediastinum.
Anyone came across any case of spontaneous pneumomediastinum ?? Personally I have 2 encounters so far.
