Abstract:
Purpose To investigate the features and diagnostic value of multi-slice spiral CT (MSCT) in eosinophilic gastroenteritis (EG).Materials and Methods The clinical and imaging data of 12 EG patients confirmed by gastrointestinal endoscope and pathological biopsy were analyzed retrospectively.The MSCT features were summarized according to the clinical classification,the location and depth of the invasion.Results Seven of twelve EG cases were mucosa type.Among them,CT of five cases with stomach involvement showed thickening and edema of the gastric wall and submucosal pseudopolyp nodules nodular shadow.Two cases with intestinal involvement showed thickening of'feather like'jejunal duplicature and saw-toothed change.Muscle type was rare and only one case in ileocecus.Thickening and stiffness of the bowel wall with intestinal stenosis and mass like change was observed.One case of serous type with coarse serosal surface,straight small vascular thickening,perienteric fiber fat thickening and small amount of ascites.Three cases of mixed type were found single invasion or multiple invasion and jumped-type development of multiple intestinal tract.Feathers of the intestinal wall stratification and multiple ring enhancement suggested that mucosal and submucosal lesions coexist with serosal lesions.Conclusion Each type of EG has its characteristic MSCT manifestation that provides objective imaging diagnosis and typing basis for the clinical diagnosis of the disease when combined with peripheral blood eosinophilia.Clinical treatment can be based on the classification and the range of involvement of EG,which is of great significance for follow-up evaluation.
