From: Tumor in the veins: an abdominal perspective with an emphasis on CT and MR imaging
A 55-year-old male with no past medical history presented with epigastric pain and severe weight loss. a Gray-scale ultrasound image demonstrated a large mass in the epigastric area (not shown) with hyperechoic thrombus within the main portal vein (arrows). There was also a focal solid lesion within the left liver lobe (arrowhead) suggestive for metastatic disease. b Axial plane postcontrast arterial phase CT image shows avidly enhancing mass (arrows) located within the pancreatic head. Imaging findings were highly suggestive for pancreatic neuroendocrine tumor (NET). Also, note is made of small enhancing nodules within the liver parenchyma suggestive for metastases (arrowheads). c Axial plane postcontrast arterial phase CT image shows enlarged right portal vein with its lumen filled with contrast enhancing tumor thrombus (arrows). Percutaneous image-guided biopsy from the mass revealed pancreatic NET
