Abstract：Objective To analyze the clinical and imaging characteristics of ectopic intrapancreatic accessory spleen(IPAS),and to explore the causes and preventive measures of misdiagnosis.Methods The clinical and imaging data of 2 patients with ectopic IPAS misdiagnosed from June to September 2022 were retrospectively analyzed.Results In both pa-tients,CT plain scan showed space occupying of pancreatic tail,MRI plain scan and dynamic enhancement showed space oc-cupying with rich blood supply,and PET-CT showed high metabolism.Both cases were diagnosed as neuroendocrine tumor be-fore surgery and underwent surgical resection.The postoperative pathology was ectopic IPAS.The misdiagnosis time lasted 53 d and 46 d respectively.Both patients had good prognosis.Conclusion The imaging findings of ectopic IPAS are atypi-cal,and it is prone to misdiagnosis as neuroendocrine tumor.Therefore,the radiologists should strengthen the understanding of the imaging characteristics,diagnosis and differential diagnosis of this disease,and improve the diagnostic accuracy.
