Lana Beth Winkler MD, Presenter: Nothing to Disclose

Jeffery Hogg MD, Abstract Co-Author: Nothing to Disclose

1) Diaphragmatic hernias are a common finding on radiological imaging and can be attributed to a variety of causes including congenital, traumatic, or idiopathic. 2) Complications, such as small bowel obstruction and compromise of lung development, can occur as a result of diaphragmatic hernias. 3) Utilizing imaging clues, such as the “dependent viscera sign" and “collar sign”, will help radiologists better identify this diagnosis. 4) Certain diaphragmatic abnormalities, such as phrenic nerve injury or paralysis, mimic diaphragmatic hernias on imaging, and differentiation may be made with clinical context.  

The learner will be prompted with questions followed by answers and explanations through a variety of diaphragmatic hernia presentations and mimics of diaphragmatic hernias. Topics of discussion include: - Pediatric presentation of congenital diaphragmatic hernias (imaged with prenatal ultrasound and MRI) - Adult presentation of congenital diaphragmatic hernias (Bochdalek & Morgagni hernias) - Traumatic diaphragmatic hernia/Diaphragm rupture (with images demonstrating "dependent viscera sign" and      "collar sign") -  Diaphragmatic paralysis due to phrenic nerve injury (mimic of a diaphragmatic hernia) -  Complications (images demonstrating a small bowel obstruction) -  Treatment
