Intestinal deformity manifests as pouch elimination, lumen narrowing and intestinal shortening. It is obvious in the acute stage, and with the subsidence of inflammation, part of the pouch shape can be restored, but it is difficult to restore the unnamed grooves and so on in the mucosal surface. It is a primary mesenteric tumor of incidence although not high, mostly seen in men, male to female ratio of 3:2 or 2:1, can occur at any age, but individual embryonic tissue residual source of the tumor, so what examination needs to be done to confirm the diagnosis of intestinal deformation? Now, the following two examination methods are introduced: 1. X-ray: Plain film of abdomen can show deep mass shadow with uniform density, in which if there are scattered calcification, bone or teeth shadow, it suggests that it is teratoma or low malignant sarcoma. If there is intestinal gas shadow, it suggests that the tumor presses the intestinal lumen, or violates the intestinal wall and enters into the intestinal lumen to cause incomplete intestinal obstruction. Barium meal and barium enema can indirectly show the location and size of the tumor, deformation and displacement of intestinal pressure, and whether there is any infiltration of the tumor in the intestinal lumen, etc. Generally speaking, the imaging can show a deep and uniform density of mass shadow. Generally speaking, the intestinal tubes shown by contrast are curved around the tumor, and the degree and direction of displacement of the intestinal tubes can be diagnosed whether the tumor comes from the mesentery of the small intestine or the mesentery of the colon; when the tumor infringes on the intestinal wall, the intestinal tubes are stiffly shaded and the mucous membrane lines are thickened or interrupted, and the narrowing of the intestinal tubes can be shown as well. Ultrasonography: the diagnosis can be made from the volume of tumor, border echo, peripheral echo and internal echo of tumor. For mesenteric cystic tumors, there are liquid dark areas, clear border echoes, obvious peripheral echoes and posterior enhancement effect. Benign tumors are small in size, with clear and intact periphery, and the internal echogenic area is uniform and sparse, sometimes or partly silent, such as lipoma, fibroma and social sheath tumor, etc. Malignant tumors are large in size, with internal hypoechoic and obvious boundary, often suggesting low malignant tumors, such as liposarcoma, fibrosarcoma, etc. Tumors of high malignancy may have or have no peripheral echogenic area, but the internal echoes are of different strengths, uneven distribution, and have irregular morphology. Highly malignant tumors may or may not have peripheral echogenic areas, but the internal echoes are of different intensity and distribution.
