ABSTRACT

Objective To evaluate the manifestations and diagnostic value of CT enterography (CTE) in primary intestinal T-cell lymphoma (PITCL).Methods Eighteen patients with PITCL confirmed by pathology were reviewed retrospec tively.The characteristics of lesion site,amount of foci,pattern and degree of contrast enhancement,lymphadenopathy,involvement of other organs and complications were recorded.Results In all of the 18 patients with PITCL,multiple lesions were seen in 13 cases (13/18,72.22％),and solitary involvement was seen in 5 cases (5/18,27.78％).Twelve ca ses were located at jejunum/ileum,3 of them were also involved in the colon.Five cases were located only in the colon,and 1 in the duodenum.Six cases were complicated with intestinal perforation.The patients were categorized into 6 types according to the CT manifestationinfiltration type (n=7),diffuse jejunum mucosa ileum metaplasia type (n =3),luminal aneurismal dilatation type (n =3),polypoid mass type (n =2),mesentery type (n=1),mixed type (n =2).Conclusion CTE can clearly display the imaging of PITCL and it has high value for the diagnosis of PITCL.
