Comparative study of intestinal tuberculosis and primary small intestinal lymphoma

Figure 1 Computed tomography, endoscopic and pathological changes of intestinal tuberculosis in a 38-year-old man. A: Plain computed tomography (CT) scan showed bowel-wall thickening (7.2 mm) and intestinal stricture in the ileocecum; B: During the arterial phase, contrast-enhanced CT demonstrated moderately stratified enhancement; C: Endoscopic examination showed rodent-like ulcer, ring-like ulcer and intestinal stricture in the ileocecum; D: Microscopic findings showed granulomas with caseous necrosis (hematoxylin and eosin staining; original magnification, 400 ×).

Figure 2 Computed tomography and endoscopic changes of intestinal tuberculosis in a 43-year-old man. A: Plain computed tomography (CT) scan showed bowel-wall thickening in the ileocecum; B: During the arterial phase, contrast-enhanced CT scan demonstrated moderate homogeneous enhancement; C: Mesenteric necrotic lymph nodes and comb sign were noted on coronal CT imaging; D: Endoscopic examination showed a ring-like ulcer in the ileocecum.

Figure 3 Computed tomography and endoscopic changes of primary small intestinal lymphoma in a 37-year-old man. A: Plain computed tomography scan showed mesenteric lymphadenectasis (19 mm); B: Endoscopic examination showed intestinal hemorrhage in the ileocecum.

Figure 4 Computed tomography and endoscopic changes of primary small intestinal lymphoma in a 39-year-old man. A: Plain computed tomography (CT) scan showed bowel thickening in the distal ileum; B: During the arterial phase, contrast-enhanced CT scan demonstrated mild enhancement; C: Endoscopic examination showed a raised lesion in the ileum.
