Calcified gastric cancer--CT findings before and after chemotherapy. Case report and discussion of the pathogenesis of this type of calcification.

Diffuse calcifications in primary gastric cancer are very rare, most of them being found in mucinous adenocarcinoma. We present the CT aspects of a locally advanced gastric cancer, which showed partial response to neo-adjuvant chemotherapy. The pathological features of the surgical specimen after total gastrectomy are also reported and the pathogenesis of the calcifications is discussed.
