Novel Endosonographic Findings in Cronkhite-Canada Syndrome

Figure 1 The CT scan shows markedly thickened gastric walls in a patient with Cronkhite-Canada syndrome.

Figure 2 Since there has been at least one report of gastric adenocarcinoma occurring in Cronkhite-Canada syndrome, endosonography was performed to further investigate the gastric wall thickening. This study revealed distinctive submucosal cystic structures. Fine-needle aspiration of the largest cyst was performed; cytology was negative. The significance of these submucosal cysts is not known.
