The article analyses MR examinations of 160 patients with interstitial acute pancreatitis, in absence of MR signs of necrosis of pancreatic parenchyma; the incidence of fluid collections and their outcomes are estimated. Small single fluid collections in the first day after an attack of acute pancreatitis were revealed in 27.5% of cases, multiple and large fluid collections without signs of parenchymal necrosis were revealed in 15.6%. Follow-up MR examinations showed full resolution of peripancreatic fluid collections in 78.7% of cases. Resistant unencapsulated and partially encapsulated collections were found in 7 of 47 patients (14.9%). Local complications requiring surgical intervention developed exclusively in patients with fluid collections and amounted to 1.9% of the whole group of 160 patients, and 6.4% of patients with acute pancreatitis without signs of necrosis of pancreas and peripancreatic fat, but with fluid collections.The authors came to the conclusion that routine MR examinations of patients with interstitial acute pancreatitis were indicated for patients with fluid collections to estimate the dynamics of changes (resolution of collections or development of complications).
