Preoperative contrast-enhanced abdominal computed tomography (CT) scan, axial arterial phase. The images reveal a low-density mass (red arrow head) measuring about 8.2 x 7.6 cm in diameter and prominently involving the uncinate process of the pancreas. The pancreatic head and neck are displaced and splayed around the anterior aspect of the tumor, certainly abutting the superior mesenteric artery (SMA; red arrow).

An abdominal computed tomography (CT) scan with contrast revealed an 8.2 x 7.6 cm heterogeneous-enhancing lesion, prominently involving the uncinate process of the pancreas (Fig. 1).
Histopathological photomicrographs of a solid pseudopapillary tumor (SPT). The image shows that the small round cells arranged and formed into nests, pseudopapillae, and microcysts. Note the tumor cells are traversed by a delicate vascular network. (Hematoxylin and eosin, original magnification, x20).

Pathological analysis of the surgical specimen revealed the tumor to be a solid pseudopapillary neoplasm (Fig. 2).
(A, B) Contrast-enhanced abdominal CT scan on postoperative day 1. A = axial. B = coronal. The images reveal an intraluminal thrombus (red arrow) in the proximal SMA ~1.5 cm from its aortic origin, causing near complete occlusion of the SMA.

SMA reconstruction, an abdominal CT with intravenous contrast was obtained and revealed an intraluminal thrombus in the proximal SMA, ~1.5 cm from its origin off the aorta, causing near complete occlusion of the SMA (Fig. 3). She was therefore returned to the operating room where the proximal jejunum appeared ischemic.
