Magnetic resonance imaging (MRI) and computed tomographic (CT) scans of the thoracolumbar spine from the first admission revealed no organomegaly, normal abdominal aorta, and diffuse degenerative spine changes (see Fig. 1).
Computed tomography - chest, abdomen, and pelvis from the second admission: The celiac artery is now severely narrowed with surrounding soft tissue density, consistent with celiac artery dissection, as shown by the arrow. The soft tissue density represents infiltration of fat.

The common hepatic, splenic, left gastric, superior mesenteric, renal, and inferior mesenteric arteries were patent (see Fig. 2).
Computed tomographic angiography (CTA) 4 days after diagnosis: The CTA confirmed celiac arterial dissection. No major change in the appearance of this process compared with previous CT, as shown by the arrow. No pseudoaneurysm formation. There is no evidence for hepatic or splenic infarction. The aorta is unremarkable and unchanged.

The patient was observed and subsequent CT angiography (CTA) 4 days later did not reveal worsening of the dissection or formation of a pseudoaneurysm (see Fig. 3).
