Distinguish Of Ilium Tuberculosis And Langerhans Cell Histiocytosis In Childern

Objective:The purpose of the study is to analysis and summary the imaging lesions features of iliumin children Focus on the distinguish of ilium tuberculosis and Langerhans cell Langerhans cell histiocytosis.Methods:Retrospective analysis of the X line,CT findings and pathological findings of 97 cases of ilium bone lesions in our hospital from November 2011 to June 2020,Statistical analysis of symptoms,imaging findings,blood routine and CRP of children with ilium tuberculosis and LCH were collected.Results:The findings have demonstrated that primary ilium tumor was found in 19 patients,Adrenal cancer transport to ilium was found in 1 patients,Osteomyelitis(n=13),ilium cyst(n=4),Langerhans cell histiocytosis(n=37),ilium fibrous dysplasia (n=3),ilium tuberculosis(n=20).The clinical manifestation and Imaging findings of ilium tuberculosis and LCH are similar.The rate of hip involvement in children with tuberculosis was significantly higher than that of LCH.No lesions of bone nodules in the skull were observed in children with tuberculosis in the ilium;no lung involvement was observed in children with LCH in the ilium;the area of bone damage was LCH>TB,and the difference was statistically significant.Conclusion:There are many types of ilium lesions in children,with different imaging manifestations.There are obvious differences between ilium LCH and tuberculous imaging manifestations.Comprehensive analysis of imaging features and clinical manifestations is helpful to make a definite diagnosis,but the final diagnosis still needs to be combined with pathological examination.
