Intramural Duodenal Hematoma with Acute Pancreatitis in a Patient With an Overt Pancreatic Malignancy.

Intramural hematomas have rarely been associated with pancreatitis, and to date there is only 1 case report of an intramural hematoma occurring with pancreatic adenocarcinoma. We describe a patient who presented with gastric outlet obstruction secondary to a spontaneous intramural duodenal hematoma and was found to have a pancreatic adenocarcinoma on endoscopic ultrasound (EUS) after it was not visualized by computed tomography (CT).

High risk of acute pancreatitis after endoscopic ultrasound-guided fine needle aspiration of side branch intraductal papillary mucinous neoplasms.

Background And Objectives: Data on the risk of acute pancreatitis following endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreatic cystic lesions are limited. The aim of our study was to evaluate the frequency of acute pancreatitis after EUS-FNA of pancreatic cysts and solid lesions, and determine whether there was a difference in pancreatitis risk in patients with side branch intraductal papillary mucinous neoplasms (SB-IPMN).

Patients And Methods: A retrospective review of patients who underwent EUS-FNA of pancreatic cysts and solid lesions was performed.

Undifferentiated Carcinoma with Osteoclast-Like Giant Cells of the Pancreas in a Patient with New Diagnosis of Follicular Non-Hodgkin's Lymphoma.

Pancreatic tumors with osteoclast-like giant cells are rare, with only 50 cases published to date. We report a case of a 67-year-old male with a new diagnosis of follicular non-Hodgkin's lymphoma with an incidental pancreatic body mass on abdominal imaging. Cytology from the pancreatic mass obtained via endoscopic ultrasound-directed fine-needle aspiration (EUS-FNA) revealed an undifferentiated carcinoma with osteoclast-like giant cells.
