title: [A case of groove pancreatitis associated with duodenal ulcer].
abstract: We describe a 69-year-old man with a history of multiple gastroduodenal ulcers, presenting with the onset of obstructive jaundice. Abdominal CT, MRI and EUS demonstrated a sheet-like mass in the pancreaticoduodenal groove. EUS-FNA did not reveal malignancy. Conservative treatment did not improve his clinical condition and repeated acute pancreatitis occurred during his treatment. Thus, pancreaticoduodenectomy was performed. Histopathological findings showed a duodenal ulcer penetrating the pancreas and infiltration of inflammatory cells and fibrosis in the pancreaticoduodenal groove. The spread of inflammation associated with the duodenal ulcer may have been one of the causes of groove pancreatitis.
