Aims and objectives: Chronic pancreatitis has been defined as a chronic inflammatory condition characterized by fibrosis and destruction of the exocrine and eventually endocrine tissue of the pancreas, leading to pain and permanent loss of function [1, 2]. The main cause of chronic pancreatitis is alcohol abuse. Nonethe[...]

Methods and materials: Between 2007 and 2016, 30 patients (20 men, 10 women; mean age, 47 years; range 21-73 years) with autoimmune pancreatitis underwent imaging study in our Radiology Department in the Universidad de Chile Clinical Hospital, with our multidetector row helicoidal CT and our 1.5-T MR system. Helical compu[...]

Results: In our study, 13 patients (43%) had diffuse disease and 17 (57%) had focal disease (see Table 1). Twelve of these 17 patients (59%) had involvement of more than one segment of the pancreas parenchyma (Table 2), in which the tail was the most commonly affected area (13 of 17 patients; 76%). The secon[...]

Conclusion: Autoimmune pancreatitis is a type of chronic pancreatitis characterized by its fibro-inflammatory glandular involvement. It can be focal or diffuse, with our series having a slightly higher incidence of focal cases, with 57%, against 43% of diffuse disease. The tail was the most commonly affected pa[...]
