“…Inoue and Nakamura described five patients, two with hypoplasia and three with aplasia, and all had intestinal nonro- tation [12]. Although they found hypoplasia of the uncinate process in three of 101 patients with normal intestinal rotation, none of these patients had aplasia.…”

Intestinal malrotation as an incidental finding on CT in adults

Intestinal malrotation can be diagnosed on CT by the anatomic location of a right-sided small bowel, left-sided colon, an abnormal relationship of the superior mesenteric vessels, and aplasia of the uncinate process. Awareness of these abnormalities is necessary to diagnose this anomaly. It should be sought in patients with a situs problem, inferior vena cava anomalies, polysplenia, or preduodenal portal vein. Although usually an incidental finding, it is important to diagnose such a malrotation because it may cause abdominal symptoms. Also, knowledge of associated vascular anomalies is important when abdominal surgery is planned.

“…When agenesis of the dorsal pancreas is suspected, it is critical to rule out pancreatic carcinoma with upstream atrophy of the gland (36). Isolated hypoplasia of the uncinate process has also been reported (37).…”

A wide spectrum of anomalies of the pancreas, the pancreatic ductal system, and the biliary tree are commonly encountered at radiologic evaluation. These anomalies may simulate various neoplastic, inflammatory, and posttraumatic conditions and should be part of the differential diagnosis for a variety of abnormalities found at diagnostic imaging. Anatomic variants, developmental anomalies (eg, pancreas divisum, annular pancreas, ectopic pancreas, pancreatic agenesis and hypoplasia), and congenital diseases (congenital pancreatic cysts, von Hippel-Lindau disease, choledochal cysts), in addition to potential imaging pitfalls (uneven distribution of fat, "pseudomasses"), can all pose a diagnostic challenge for the radiologist. Familiarity with these anomalies, the imaging techniques available for their study, and their variable imaging manifestations is necessary for differentiating them from other biliary and pancreatic conditions. A basic understanding of the embryologic development and normal anatomy of the pancreas and biliary tree is also essential for identifying these anomalies.

“…The uncinate process was defined as the dorsal portion of the pancreatic head located left to the line linking the SMV and the right border of the inferior vena cava (IVC) [9,10]. Tumor locations were classified as at the uncinate process or non-uncinate process cancer of the pancreatic head, based on computed tomography (CT) findings.…”
