title: Primary extrapulmonary small cell carcinoma involving the stomach or duodenum or both: findings on CT and barium studies.
abstract: 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.
  
  
  CONCLUSIONS
  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.
