Abstract:
Objective To explore the imaging typing of skull eosinophilic granuloma( SEG) in children,and the clinical significance of this typing system was determined. Methods The clinical and radiological data of 32 cases of SEG confirmed by pathology in the past six years were retrospectively reviewed. According to the imaging findings,which included the size and shape of the granuloma,and the degree of skull destruction,SEGs were divided into four types:typeⅠ( subtle granumoma) ,typeⅡ( exteriorly convex granuloma) ,typeⅢ( biconvex granuloma) and typeⅣ(multiple granulomas and destructions). The imaging features of different types of SEG were analyzed,and the signif-icance of imaging typing was explored combining with the clinical manifestations,treatment programs and prognosis. Results Three cases (9. 4%) were included in typeⅠ,in which,the granuloma was not obvious and the skull destruction was confined in the diploe and outer plate. In type Ⅱ (21 cases,65. 6%),the imaging features included an obvious exteriorly convex mass and complete skull destruction of in-side and outside panels. Granuloma remove and destructed skull repair were performed in all cases,in which 15 were followed up and no re-currence was found. The imaging features of type Ⅲ (5 cases,15. 6%) were biconvex mass which broke through the inner plate and op-pressed the dura and cerebral parenchyma. Therapy program included not only surgical excision of the lesion but also repair of skull and dura. Three cases were followed up and no recurrence was found. Type Ⅳ (3 cases,9. 4%) showed multiple skull destructions and granulomas of various sizes. Chemotherapy and surgery treatment,poor prognosis and ease recurrence were characterized by this type. Conclusion we put forward a imaging typing method for SEGs. This typing system is helpful in guiding clinical protocols and prognosis of SEGs in children.
