Abstract:  Objective　To avoid to mix pseudocysts of splenic hilum (POSH) with introsplenic pseudocysts or peripancreatic fluid collections, radiological images and the second Chinese Visible Human (CVH2) datasets were used to summarize the classification of the POSH, and to explore potential correlation between the POSH and the sinistral portal hypertation (SPH).　Methods　The classification of POSH was summarized on CT or MRI from 291 patients with chronic pancreatitis in 2019. The classification of the POSH discovered on radiological images was mimicked on CVH2 images. The potential correlation between the POSH and the SPH was explored by statistical analyses.　Results　The POSH might be classified into three categories: one was that pseudocysts of pancreatic tail (POPT) developed to the splenic hilum area and extended into the splenic parenchyma to form the POSH, another one was that the POSH developed from the fistula of the pancreatic duct, and the third one was that both the POPT and the pancreatic fistula formed the POSH. The presence of a POSH was a risk factor for the SPH (OR=7.88; P<0.001).　Conclusions　The classification of the POSH has been summarized and displayed virtually by visualization technology. Mastering the detailed types of the POSH will decide on the choosing of the therapeutic strategy.
