Pancreatic pseudoaneurysm mimicking pancreatic tumor: A case report and review of literature

Figure 1 Representative computed tomography and magnetic resonance imaging. A: Computed tomography (CT) showing enlargement of the pancreatic head with unclear borders and scattered irregular calcifications (orange arrow); B: Axial view of contrast-enhanced CT reveals a slightly enhanced intrapancreatic lesion in the head of the pancreas (orange arrows); C: CT show generalized dilatation of the main pancreatic duct and mild atrophy of the distal pancreas (orange arrow); D: Magnetic resonance imaging (MRI) showing a low attenuation lesion in the center of the pancreatic head (orange arrow); E: Contrast-enhanced MRI axial view reveals uniformly mild enhancement within the lesion (orange arrows); F: MRI show significant dilatation of the main pancreatic duct with mild atrophy of the distal pancreas (orange arrows).
