[Diagnostic imaging of pancreatic metastasis]

The authors present their personal series of pancreatic metastases (8 cases) which were evaluated with different imaging modalities--i.e., sonography, computed tomography, and angiography. Possibilities and limitations of non-invasive modalities are pointed out, and the usefulness of angiography is emphasized for the identification of small hypervascular lesions. The fairly rare diagnosis of these tumoral lesions is due to 3 causes: low incidence of pancreatic metastases; their frequently small size which justifies eventual false negatives; the frequent lack of symptoms calling for imaging modalities. Moreover, pancreatic metastases are usually diagnosed in an advanced stage. Thus, the therapeutic approach must be planned in every single case, in relation to the perspectives of survival and to the residual quality of life.
