- Abstract: Objective To investigate multidetector computed tomography (MDCT) features of solid pseudopapillary tumor of the pancreas (SPTP) in pediatric patients. Methods Clinical data and MDCT findings of 10 pediatric patients with SPTP confirmed by surgery and pathology were retrospectively reviewed, and then the MDCT features were summarized. Results All the patients were female, and all the cases were of single lesion. Among the tumors, 3 located at the pancreatic head and neck, and the other 7 at the pancreatic body and tail. The maximum diameters of tumors were 2.5-13.8 cm, with an average of 5.94 cm. Eight tumors were round-like and 2 were lobulated. All tumors were well-circumscribed and 8 tumors had complete capsules. On CT images, 1 tumor showed homogeneous low density without enhancement, and the other 9 tumors consisted of solid and cystic component, with 8 cases containing mostly solid components and 1 case containing similar proportion of solid and cystic components. Subcapsular calcification was only found in 1 case. After contrast-enhanced scan, the solid components presented slight enhancement in the arterial phase, with an enhancement lower than normal pancreas, and progressive heterogeneous enhancement in the portal venous phase. The cystic components showed no enhancement. Mild dilatation was observed at bile duct and pancreatic duct in 1 case, and only pancreatic duct dilatation was found in another case. No patients developed liver or lymph nodes metastasis. Conclusion Pediatric SPTP often occurs in female patients. The characteristic CT features of SPTP play an important role in the diagnosis and differential diagnosis.
