Methods The computed tomographic findings in 21 patients (18 women and 3 men) with pathologically proven solid pseudopapillary tumor of the pancreas were reviewed retrospectively. Two radiologists reviewed images for location, size and morphology, capsule and margin, density, enhancement pattern, calcification, dilatation of pancreatic duct, lymphadenopathy, vascular invasion, distant metastasis, and recurrence. Results On CT, the lesion presented as solitary, round (28.57%), oval (57.14%), or lobulated (14.28%) mass in pancreatic head (47.62%) with complete capsule (85.71%). Lesions smaller than 4cm in maximum diameter (47.62%) presented as predominantly solid mass whereas lesions greater than 4cm in diameter (52.28%) presented as heterogenous mass. On contrast administration, the viable solid portion of the tumor showed mild peripheral enhancement in arterial phase [enhancement degree<20Hounsfield unit (HU)] with progressive fill in during the portal and hepatic parenchyma phase (enhancement degree 20-40HU). Eighteen lesions (85.7%) had complete capsule. Two lesions (9.5%) had areas of high density (>60HU) on plain CT which due to hemorrhage. Dilatation of the pancreatic duct was rare (25%), and distant metastasis, regional lymphadenopathy, and tumor recurrence were absent. Nine patients (42.85%) had an abdominal CT follow-up for 24.55months (range, 2-60months) post-surgery without recurrence or distant metastasis. Conclusion Solid pseudopapillary tumor of the pancreas usually occurs in young females in the pancreatic head or tail. On CT, they manifest as moderate vascular mixed tumor, progressive enhancement of the viable solid portion, distinct tumor margin with capsule formation, and absence of regional lymphadenopathy.展开更多
