Groove pancreatitis: Imaging features and management

GP is a disease that should be considered in the list of differential diagnosis of masses implicating the pancreatic head and medial duodenal wall. Imaging findings that are suggestive of GP include chronic inflammatory changes with fibrosis in the PD groove with or without implication of the nearby head of the pancreas, duodenal medial mural thickening with luminal stenosis and cysts at the PD groove or within the duodenal wall. Vascular invasion is a sign against diagnosis of GP.
