Recurrent spontaneous pneumomediastinum in an adult

Abstract

Spontaneous pneumomediastinum (SP) is defined as the presence of free air in mediastinal space without any apparent cause. This rare entity is most likely to occur in young males often related to an episode of vomiting, asthma or sustained physical activity. SP usually resolves spontaneously in few days of treatment based on rest and analgesia. Complications are extremely rare. Its recurrence has been poorly reported but seems exceptional. We present a case of recurrent SP occurring in a 21-year-old male with a mental deficiency. The recurrence occurred after a free-interval of 12 months. We proposed a literature review. © The Author 2011. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery. All rights reserved.
