Аннотация
OBJECTIVE: This pictorial review aimed to summarize the most possible differential diagnosis of pancreatic islet cell tumor (PICT).
DATA SOURCES: Data used in this review were mainly from Medline and Pubmed in English. And all clinical images in this review were from Department of Radiology, Peking Union Medical College Hospital, Beijing, China.
STUDY SELECTION: Cases of pancreatic cystadenoma, solid pseudo-papillary tumor of the pancreas, pancreatic metastasis, pancreatic adenocarcinoma, para-pancreatic neuroendocrine tumors, Castleman disease, gastrointestinal stromal tumor, splenic artery aneurysm and accessory spleen were selected in this pictorial review for differential diagnosis of PICT.
RESULTS: Careful analysis of imaging features and correlation with the clinical manifestations may allow a more specific diagnosis. It is also important that the radiologist is familiar with the anatomic variants and disease entities which mimic pancreatic islet cell tumor in order to avoid an improper treatment protocol.
CONCLUSIONS: Many congenital anatomic variants or other pancreatic and peri-pancreatic diseases may mimic MDCT appearance of pancreatic islet cell tumor. Radiological, clinical and pathological characteristics should be considered for the final diagnosis.
