A 56-year-old male patient, hypertensive, diabetic and asymptomatic, underwent abdominal computed tomography (CT) with intravenous contrast for follow-up of hepatic steatosis. Computed tomography demonstrated a solid hypervascular nodule in the pancreatic head (characteristics of neuroendocrine lesion – ) and oval formation anteriorly to the aortoiliac bifurcation (). In this situation, axial CT can mimick lymph node enlargement, especially in clinical oncology context. However, evaluation of the different phases of the exam and the reformatted coronal and sagittal images help making […]
