The Asymptomatic Dissecting Aortic Aneurysm: An Incidental Finding On CT

Abstract

We report a case of 65-year male patient, a known hypertensive and a chronic smoker, who presented to the Civil Hospital, Karachi with complaints of cough, hemoptysis and shortness of breath for three weeks. The chest radiograph showed left apical solitary pulmonary nodule (SPN) and aneurysmal dilatation of the descending thoracic aorta. He was further investigated with contrast enhanced computed tomography (CECT) scan of chest, which apart from demonstrating malignant pulmonary lesion, surprisingly revealed Stanford type B descending thoracic aortic dissecting aneurysm with intramural hematoma, jeopardising renal and splanchnic circulation. An asymptomatic dissecting aortic aneurysm is relatively rare. To the best of authors' knowledge, less than 15 case reports have been published in the international literature.

Giant saccular abdominal aortic aneurysm with manifestation of gastric inlet obstruction mimicking a fundal gastrointestinal stromal tumor: A report on an unexpected case

“…2,5 Computed tomography scan has the specificity and sensitivity necessary for detecting aortic aneurysms and is sufficient for an accurate and complete diagnosis. 6 Treatment approach to these aneurysms is open surgery or endovascular aortic repair. However, not every aneurysm is an indication for the treatment, and symptomatic aneurysms or aneurysms larger than 5 or 5.5 cm are candidates for surgical removal.…”
