Abstract
Background: Acute aortic syndromes include a range of life-threatening conditions with the most familiar entity being aortic dissection. However, variants of aortic dissection also include intimal tear without hematoma, aortic intramural hematoma, and lastly penetrating aortic ulcer (PAU), which will be the focus of this case report. Most PAUs are located in the descending thoracic aorta (85-95%), but they can also occur in the ascending aorta or arch as in the current case. Case Presentation: We report a case of a 77 year old male who presented with chief complaint of intermittent right-handed weakness associated with no numbness or mental status changes. Patient was admitted for stroke workup with unrevealing findings on CT (computed tomography) for acute abnormalities or any hemodynamically significant stenosis on carotid ultrasound. CT angiogram of head/neck revealed a penetrating aortic ulcer of the lateral aspect of the mid to distal ascending aorta. Patient was then transferred for further evaluation to a center of higher level care for further management. Conclusions: Patient was evaluated for surgical repair of penetrating ascending aortic ulcer. Patient underwent serial imaging throughout hospital course which showed grossly similar findings to prior examination and thus no surgical intervention was needed at that time. Patient was recommended to have follow up CT scan in one month to monitor progression of aortic ulcer, however patient lost to follow-up thereafter. Penetrating aortic ulcers are rarely located in the ascending aorta and are considered precursors of life-threatening aortic dissections.
