Spontaneous pneumomediastinum, pneumoretroperitoneum, and cervicofacial subcutaneous emphysema after repeatedly and forcefully blowing into a bottle

Spontaneous pneumomediastinum (SPM) is an uncommon, self-limiting condition associated with increased intra-thoracic pressure resulting in alveolar rupture. Search of the literature revealed no detailed case report about a 26-year-old psychiatric patient who repeatedly and forcefully blew air into a bottle for 5 days resulting in a combined condition of spontaneous pneumoretroperitoneum, pneumomediastinum, and cervicofacial subcutaneous emphysema. It is crucial to find a primary source and treat appropriately. Psychiatric patients may have psychotic behaviors mimicking Valsalva’s maneuver that increases intra-thoracic pressure and causing SPM. Optimal medications should be given to control psychotic behaviors. Family members and caregivers should be explained about this unusual behavior so that they can prevent this rare condition.
