Intrapancereatic abscess due to arteriovenous malformation involving the entire pancreas: A case report and review of the literature

Abstract

Introduction: The described case is a patient with pancreatic arteriovenous malformation involving the entire pancreas and complicated with intrapancereatic abscess.

Presentation of case: A 47 years-old was suffering from episodes of abdominal pain and vomiting with multiple hospital visits without reaching a diagnosis for four months. Contrast-enhanced computed tomography scan (CECT) done which shows a 1.6×1.4cm fluid collection was seen in uncinate process of the pancreas, Magnetic resonance imaging (MRI) demonstrates abnormal vasculature involving the pancreas. Therefore patient diagnosed as a case of pancreatic arteriovenous malformation (P-AVM), which confirmed by Selective Computed Tomography Angiogram (CT Angiogram).

Discussion: Normal investigations in the first attempts can lead to miss pancreatic arteriovenous malformation (P-AVM), and can lead to serious and fatal.

Conclusion: Early diagnosis and treatment of (P-AVM) is very important even in asymptomatic patients. Conservative treatment in complicated and big P-AVM appears ineffective as surgical resection.
