Computed Tomographic Findings of Syphilitic Aortitis: A Case Report

Abstract

We describe the computerized tomographic (CT) findings of the aortic wall in a case of acute-phase syphilitic arteritis. The delayed phase of the contrast-enhanced CT shows a double-ring configuration of the thick thoracic aortic wall, which is similar to CT findings previously reported for Takayasu arteritis. We speculate that the resemblance of the CT findings for these two diseases accounts for their similar histopathological features.

Syphilitic aortitis complicated by multiple aortic aneurysms: findings of multidetector CT

“…Chest radiograph shows a widened upper mediastinum and linear calcifications along the ascending aorta. A CT can sometimes shows a double-ring appearance of the aortic wall with a hyperdense outer rim and a hypodense inner rim [6]. Syphilitic serology is the most reliable aid leading to the underlying etiology; however these tests are not always positive.…”

Aortitis

“…Location of the lesion is also typical, i.e. opposite the origin of aortic branches aortic wall may have a double-ring appearance mimicking Takayasu aortitis [ 66 ]. Giant syphilitic aneurysms involving the thoracic aorta and determining sternum erosion or rightward displacement of the mediastinum have been described [ 67 , 68 ].…”

Cross-sectional imaging of aortic infections

“…The most common appearance on CT/MR is diffuse aortic mural thickening with associated aneurysm formation, which may be multiple and saccular (Fig. 12) [70]. Syphilitic thoracic aortic aneurysms may grow to considerable size, and can cause sternal or clavicle erosion [71].…”
