Tumors of the spleen areeasily recognized by the deformity theygive in the barium-filled stomach and bythe deformity of the splenic flexure withthe barium enema. The enlarged organwith its smooth, even contour may be seendisplacing the stomach to the right withthe greatest pressure near the fundus,giving the stomach an atypical hour-glassappearance. The splenic flexure is dis- located downward, and the lower poleof the organ may be outlined by the latterpart of the transverse and the splenicflexure. Unfortunately, various types of splenictumor give the same radiologicalappearance and the etiology of the tumorhas to be arrived at by other methods ofexamination. In cases of tuberculosis ofthe spleen the calcified plaques often areot aid in the correct diagnosis. We were. Fig. II. No. 85691.
