Objective To analyze the diagnosis and treatment of pancreatic sinistral portal hypertension (PSPH).Methods A total of 28 patients with PSPH were retrospectively analyzed,and the clinical characteristics,diagnosis and treatment experience of the disease were summarized.Results There were primary pancreatic diseases in all the cases,including 16 cases of pancreatitis and 12 cases of pancreatic tumor in the tail.12 cases underwent distal pancreatectomy plus spleenectomy,2 cases did spleenectomy and pericardial devascularization,9 cases received miscellaneous surgical procedures,and 5 case were managed by non-surgical medical treatments.After 1 year of follow-up,20 of 23 postoperative patients were alive and well.Among the 5 conservatively treated patients,2 had repeated upper gastrointestinal bleeding.Conclusion PSPH,especially caused by chronic pancreatitis yields to personalized surgical procedures based on pancreatectomy.

Objective To analyze the CT and MRI features of splenic inflammatory myofibroblastoma (SIMF).Methods The CT and MRI images of 6 patients with SIMF were retrospectively analyzed.Results 5 cases underwent CT examination;2 cases did MRI.Six cases of SIMF were all single lesions;the average diameter was (3.9 ± 0.9) cm;the lesions were round or gourdshaped;most have clear boundaries with uneven scan density.On the MRI,the parenchymal part was slightly low signal on T1WI,inhomogeneous hypointensity on T2WI,or high signal on T2WI.After CT or MRI enhancement,lesions were progressively enhanced.Correct preoperative diagnosis was established in only 1 patient.Conclusion In this study,all SIMF cases present as single lesion.The circular appearance and clear boundaries are in common.Asymptotic intensification with map-unenhanced regions is the main enhancement feature.
