Figure 1: Axial (a) and sagittal (b) Maximum Intensity Projection (MIP) algorithm CT-angiographic images from initial total-body CT, show a roundish 3-cm aneurysm, originating from the distal branches of the superior mesenteric artery (arrowheads). Repeat CT shows a persistent mesenteric aneurysm, with internal hyperdensity, on an unenhanced image (c) and absent contrast perfusion during a vascular enhanced study (d). Color-Doppler ultrasound (e) confirms spontaneous aneurysmal thrombosis, with internal echogenicity and absent flow signals. The lesion completely disappeared on the six-month CT follow-up (f)
