Spontaneous pulmonary herniation in post-polio syndrome.

Pulmonary hernias are typically a result of trauma, thoracic operations, or congenital defects. Spontaneous lung hernias without a prior overt injury are notably rare. The presence of spontaneous lung hernias has not been reported in post-polio syndrome. Post-polio syndrome is a late sequela of poliomyelitis that usually presents 30-40 years after the initial illness with new presentations of progressive muscle weakness, abnormal muscle fatigue, muscle atrophy, and myalgia. This case report describes the presentation and imaging of a post-polio patient with an atraumatic, spontaneous lung hernia. A discussion on pulmonary hernias, diagnostic imaging, and management is also included.
