Core Tip

Core tip: Pancreatic paraganglioma is a rare disease, which has been reported only in 24 cases ever. Invasive procedures toward paragangliomas carry the potential risk of catastrophic complications due to unexpected release of large quantities of catecholamines. An accurate diagnosis of paraganglioma, therefore, is important before invasive procedures. Draining vessels from the tumour are sometimes observed in a general paraganglioma. However, it is still unclear in the pancreatic paraganglioma. In the present report, usefulness of draining vessels for a diagnosis of pancreatic paraganglioma was investigated by reviewing past cases.
