[Spontaneous pneumomediastinum (Hamman's syndrome) with pneumorrhachis as a rare cause of acute chest pain in a young patient with acute asthma exacerbation]. / Spontanes Pneumomediastinum (Hamman-Syndrom) mit Pneumorrhachis als seltene Ursache für akuten Thoraxschmerz bei einem jungen Patienten mit akut exazerbiertem Asthma bronchiale.

Pneumomediastinum, defined as abnormal presence of air in the mediastinum, is a rare cause of acute chest pain. The condition may occur spontaneously as well as a secondary consequence of trauma or medical interventions. The spontaneous pneumomediastinum (Hamman's syndrome) is associated with a good prognosis, even without intervention. However, undelying severe conditions such as gastrointestinal perforations should be excluded. Diagnosis might be made using conventionell chest x-ray; a CT scan may give additional useful information. A subcutanous emphysema is a common finding in patients with pneumomediastinum. The presence of air in the epidural space of the spinal canal (pneumorrhachis) is a rarely seen but likewise mostly benign complication. We report a case of a young man with Hamman's syndrome and pneumorrhachis, provoked by acute asthma exacerbation; despite pronounced symptoms, his condition could be treated conservatively.
