From: Cystic pancreatic lesions: MR imaging findings and management
Retention cyst. A small cyst is observed on T2w (a) and MRCP (b), without evidence of a mass. On a follow-up study two years later, a focal obstruction of the main pancreatic duct appeared with chronic obstructive pancreatitis features upstream (c, d), all findings of high suspicion of malignancy (pancreatic carcinoma on histology).
