Ultrasonographic and general pathologic features assessment of small intestinal lymphoma / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To study the ultrasonographic and morphologic features of intestinal lymphoma.</p><p><b>METHODS</b>The ultrasonographic and morphologic features of 19 patients with intestinal lymphoma were retrospectively analyzed. RESULTS All the patients were confirmed as non-Hodgkin's lymphoma by endoscopy or pathology. Of these 19 cases,the involved locations included ileum(n=14),duodenum(n=3),and ileocecum(n=2). The main sonographic types included mass type(n=12),bowel wall thickening type(n=1),and nonspecific signs(n=6). The mass type was characterized by solid and cystic-solid hypoechoic(including marked hypoechoic)foci,with well-defined margin,and rich blood signals were visible in large masses. The bowel wall thickening type was characterized by the thicking of bowel walls,showing hypoechoic(including marked hypoechoic),along with posterior acoustic enhancement. The nonspecific signs included e.g. dilatation of intestine and mesenteric lymph node enlargement. Morphologically,the tumor was featured by intestinal mass in intestinal mucosa or the circumferential thickening of intestinal wall.</p><p><b>CONCLUSION</b>Small intestinal lymphoma has typical ultrasonographic features,and ultrasonography can provide useful information in the diagnosis of small intestinal lymphoma.</p>
