OBJECTIVE. The purpose of this study was to evaluate the CT and
radiographic features of extrapulmonary small cell carcinoma involving the
stomach or duodenum or both.
CONCLUSION. Although the radiologic findings of extrapulmonary small
cell carcinoma involving the stomach or duodenum or both appear to be variable
and nonspecific, some distinguishing features are poor contrast enhancement,
bulky exophytic mass, and minimal peritumoral infiltration.
