Abstract:
Objective To investigate CT features of primary ileocecum lymphoma (PIL),to improve the ability of CT diagnosis for the disease.Methods CT data of 12 patients with PIL confirmed by surgery and pathology were analyzed retrospectively.All of the patients underwent plain CT, and 8 cases of them also underwent enhanced CT.Results Among the 12 cases of PIL, there were mass type in 2 and diffused thickness type in 10.The length of the intestinal lesions ranged from 7.8 to 18.5 cm (mean 10.2 cm).Lumen was irregular or aneurysmal dilation in 9, and obvious stenosis in 3.Intestinal wall was soft in 10,and rigid in 2.Plain CT showed that the thickened intestinal wall was soft tissue density.Among the 8 cases performed enhanced CT,6 were approximately homogeneous enhancement, and 2 had small necrosis area without enhancement.Maximum intensity projection(MIP) displayed the lesion had blood supply from the branches of the superior mesenteric artery.Enlarged lymph nodes were detected around the lesions, in root of the mesentery, and in the retroperitoneum in 9.1 case was accompanied with intestinal obstruction,1 case was accompanied with intestinal perforation.Conclusion If CT examination found a homogeneous soft tissue mass in ileocecum with long extent, lumen dilation, soft intestinal wall,mild-to-moderate delayed homogeneous enhancement, PIL should be considered.
