【Objective】To discuss the CT diagnosis and differential diagnosis of solid pseudopapillary tumor of the pancreas (SPTP).【Methods】The CT findings of 20 patients with SPTP proved by surgically pathology were retrospectively analyzed and summa? rized.【Results】SPTP were composed of solid and cystic components with surrounding capsule resulting to clear demarcation between tumor and normal pancreas without dilation of pancreatic duct. The tumor parenchyma was slightly hyperenhancement on arterial phase and showed gradual enhancement on venous and delayed phase.【Conclusions】The CT findings of SPTP have relative specifici? ty and can contribute to early diagnosis and differential diagnosis of SPTP.
