There was also focal widening in the dissected part of the artery and the diameter was 13 mm (Figure 1).
Sagittal reformat maximum intensity projection and curved planar reformat images showing Sakamoto type IIb dissection of the superior mesenteric artery (white arrow) and millimetric contrast accumulation in the wall due to ulceration (black arrows).

SMA, beginning just after the orifices of the first branches of SMA and extending for approximately 1.5 cm, accompanied by millimetric contrast accumulation in the wall due to ulceration in the proximal part of the artery. SMA was visualized as 50-60% narrowed because of the dissection, and it was classified as a Sakamoto type IIb dissection of SMA (Figure 2).
