METASTASES TO THE PANCREAS

Disparity in prognosis and management between primary and secondary pa ncreatic tumours makes recognition of metastases to the pancreas on CT and MRI an important goal. Three different patterns of secondary panc reatic tumours may be seen: localized, multifocal, or diffuse enlargem ent. CT findings include hypodense lesions, which show rim enhancement following intravenous contrast medium. On MR examination, the lesions are usually hypointense on T-1 weighted and hyperintense on T-2 weigh ted images.
