Spontaneous Pneumomediastinum and Subcutaneous Emphysema: Unusual Presentation of H1N1 Influenza in Adult | Chapter 16 | New Frontiers in Medicine and Medical Research Vol. 8

 Swine flu is an acute respiratory disease caused by a variant of the influenza A virus that is highly infectious. The strain has produced many localised outbreaks in various parts of the world since the 2009 H1N1 influenza pandemic. Fever, cough, sore throat, weariness, headache, dyspnea, myalgia, vomiting, and diarrhoea are the most common symptoms, although serious consequences such as rapidly progressing pneumonia, septic shock, and multi-organ failure can also occur.

Spontaneous pneumomediastinum complicating H1N1 swine influenza is unusual, occurring predominantly in youngsters with a susceptible co-morbidity such as asthma. Its occurrence in adults should be considered a possibility, notwithstanding its rarity. If Pneumomediastinum is not detected and treated soon, it can be fatal.

We present a case of adult H1N1 swine influenza that developed spontaneous pneumomediastinum (SPM) in the absence of any known comorbidities.
