Correlation Between CT Features and Peripheral Blood Eosinophil in Eosinophilic Gastroenteritis / 中国医学影像学杂志

ABSTRACT

Purpose To investigate the correlation of CT features with peripheral blood eosinophil count and proportion in eosinophilic gastroenteritis (EG).Materials and Methods Seventeen cases of clinically confirmed EG were retrospectively analyzed.The lesions were observed based on CT findings,and the count and proportion of peripheral blood eosinophil were calculated.Results Among 17 cases of EG patients,2 cases had one lesion,the peripheral blood eosinophil count and proportion of which were (0.28±0.22)× 109/L and (4.85 ± 2.19)％,respectively;5 cases had two lesions,the eosinophil count and proportion of which were (3.19± 1.82)× 109/L,(37.04± 11.36)％,respectively;6 cases had three lesions,the eosinophil count and proportion of which were (3.93 ±2.37)× 109/L and (45.22±22.99)％,respectively;3 cases had four lesions,the eosinophil count and proportion of which were (6.48±0.34)× 109/L and (75.83± 9.33)％,respectively;1 case had seven lesions,the eosinophil count and proportion of which were 8.87× 109/L and 75.60％,respectively.Conclusion There is a certain correlation of the peripheral blood eosinophil count and proportion with EG lesions.When the count and proportion of peripheral blood eosinophil increase significantly,the range of lesions may become more extensive,which suggests the scope of endoscopy or imaging examinations should be expanded in clinical work.
