A Patient of Pancreatic Acinar Cell Carcinoma with Dilated Esophagogastric Vessels

Left portal hypertension and splenic vein occlusion commonly occur with pancreatic tumors, however these signs are rarely observed in patients with acinar cell carcinoma. This report describes a rare left portal hypertension in a patient who presented with a dilated esophagogastric vein upon esophagogastroduodenoscopic examination of a gastric polyp. A contrast-enhanced computed tomography scan revealed a pancreatic tumor, with obstruction of the splenic vein and portal-systemic shunt. The patient was diagnosed with an acinar cell carcinoma of the pancreatic tail. This patient highlights that pancreatic acinar cell carcinoma should be considered as a differential diagnosis in patients with a dilated esophagogastric vein and without signs of liver disease.
