[Spontaneous idiopathic pneumopericardium in young patients. Review of the literature. Apropos of a new case].

Spontaneous idiopathic pneumopericardium (SIPP) in young subjects is a rare disorder since, apart from the case described here, only 28 cases have been reported in the literature. It occurs mainly in young adults. The physiopathology of the disorder involves alveolar rupture, as described by Macklin. The symptoms of SIPP are dominated by chest pain, which usually develops suddenly and is combined with dyspnea. Clinical examination is not very helpful, cardiac auscultation detects either pericardial rubbing or a more suggestive metallic sound. Recovery usually occurs without treatment, but there is a risk of long-term recurrence. An unusual complication to be feared is aerial tamponade, which may be life-threatening and calls for emergency draining. The treatment of SIPP involves strict bed-rest, symptomatic treatment of the pain and clinical monitoring.
