title: Radiology case of the month. Abnormally dilated arteries in an asymptomatic male. RADIOLOGIC DIAGNOSIS: Aortic coarctation. There is narrowing in the region of the aortic isthmus (arrows, Figures 2 and 4). The extent of collateral arterial dilation (arrows, Figures 1 and 3) suggests this to be a hemodynamically significant finding.
abstract: A 61-year-old male with a past medical history of chronic, uncontrolled hypertension received a non-contrasted computed tomogram (CT) of the chest and abdomen to investigate for possible Conn syndrome. This noncontrast study showed some areas of nodularity around the vertebral bodies bilaterally and extending into the posterior mediastinal region. A CT of the chest with intravenous contrast, and 3D reconstruction were then obtained.
