[Abstract] Objective: To discuss the differential diagnosis value of MRI on common mass-like lesions in ileocecal region.Materials and Methods: MRI data of 64 consecutive patients with mass-like lesions in the ileocecal region confirmed by pathology were included in this retrospective study. The morphological features, DWI and blood supply were analyzed by blinded method. The differences between chronic inflammation, tuberculosis, cancer and lymphoma were compared.Results: The study included 25 cases of chronic inflammation, 12 cases of intestinal tuberculosis, 21 cases of intestinal adenocarcinoma and 6 cases of lymphoma. The morphological features, DWI and blood supply have some characteristics: (1) The intestinal wall thickness of lymphoma was higher than that of chronic inflammation, tuberculosis and adenocarcinoma group (P<0.05), there was difference between adenocarcinoma and chronic inflammation group (P<0.05), but no difference between adenocarcinoma and tuberculous group (P>0.05). Benign lesions were prone to mucosal linear enhancement and concentric ring sign (P<0.05). (2) The ADC value of chronic inflammation, tuberculosis, cancer and lymphoma decreased in turn, these four kinds of lesions were statistically different in group comparisons (P<0.05), except intestinal tuberculosis vs adenocarcinoma (P>0.05).Conclusions: The combination of multiple sequences of MRI had some value in differential diagnosis of mass-like lesions in the ileocecal region, and it can be used as an important complement to CT-atypical lesions.
