Pancreatic paraganglioma with multiple lymph node metastases found by spectral computed tomography: A case report and review of the literature

Figure 1 Images of the pancreatic tumor. A: Non-contrast abdominal computed tomography (CT) image. White arrow indicates the strip calcification in the mass; B: Abdominal contrast-enhanced CT showed that the mass was significantly enhanced, and the abundant intratumoral vessels could be seen in the tumor; C: Maximum intensity projection (MIP) of the arterial phase in a coronal view. Red arrow indicates the draining vein into the portal vein; D-E: Abdominal MRI showed a low-intensity lesion on T1-weighted imaging (T1WI) and a hyper-intensity lesion on T2WI; F: MRCP shows no dilation of the bile duct and pancreatic duct.
