Background

Despite advances in pancreatic imaging, the unequivocal identification of a non-neoplastic process is still difficult.
Pancreatic pseudo-lesions represent a group of distinct categories that may range from benign enlargement of the gland, which clinically resembles a true neoplasm to anatomical variants and benign pathology.
Together with imaging features, radiologists can support their diagnostic differential with the support of laboratory and clinical data.
