Penetrating Aortic Ulceration With Pseudoaneurysm and Intramural Hematoma: Emergency Department Management and Point-of-Care Ultrasound Diagnosis.

Penetrating aortic ulcer (PAU) complicated by an intramural hematoma is a rare and potentially life-threatening emergency department (ED) presentation that is defined by progressive ulceration through the intima layer into the media layer of the aorta. Symptomatic PAUs can be clinically indistinguishable from other life-threatening pathologies such as aortic dissection, acute coronary syndrome (ACS), intrabdominal catastrophes as well as less lethal processes such as musculoskeletal back pain. Given the potential of PAUs to result in lethal aortic rupture and dissection, the emergency provider should maintain a high index of suspicion in patients with risk factors for aortic pathologies and utilize diagnostic modalities such as point-of-care ultrasound (POCUS) to expedite diagnosis.
