  • Abstract
  • Look Inside

 We report a case of primary malignant lymphoma of the jejunum, in which retrospective study was possible on roentgenological findings for 5 years.Preoperative radiological examination showed marked dilatation as well as thickened and flattened mucosal folds of the tumor(Figs.3-5).Histological findings were consistent with malignant lymphoma(non-Hodgkin lymphoma, diffuse, small cell type, well differentiated,B-cell type)(Fig.10).

 Retrospective analysis suggested that the following two findings were early findings of malignant lymphoma(Figs.2-5): 1)Gathering small nodular polypoid lesions, partly consistent with submucosal component, in the mucosal folds and 2)segmental thickening or flattening of the mucosal folds.

 The growth pattern of aneurysmal type jejunal lymphoma in this case was considered as follows: the tumor took infiltrative form instead of polypoid or excavated form, thus causing diffuse wall thickening and aneurysmal dilatation of the small intestine.
