Abstract:
Objective To explore the CT,clinical,and pathological features of eosinophilic lymphogranuloma(ELG)in head and neck region. Methods CT,clinical,and pathological data of 9 cases of ELG in head and neck region,confirmed by biopsy were retrospectively an-alyzed.Results Parotid gland was lonely involved in 3 cases,and cervical lymph nodes were lonely involved in 2 cases,and they were both involved in 4 cases.All of the patients suffered from painless nodule or mass in head and neck region with peripheral blood eosinophilia.On CT examination,nodular lesions of parotid gland were clear or slightly blurred defined with moderately or obviously homogeneous enhancement,and diffuse mass lesions in parotid gland were ill defined with involvement of surrounding tissue,and heterogenous progressive enhancement.The involved cervical lymph nodes were enlarged with clear boundaries,and moderately or obviously homogeneous enhancement.The pathological findings of ELG included the marked infiltration of eosinophilia,lymphocytic proliferation,lymphatic follicles,variable degrees of fibrosis and vascular proliferation.Conclusion ELG in head and neck region has some CT features,and diagnosis could be suggested combining with the clinical manifestations and peripheral blood eosinophilia. The final diagnosis depends on histopathological examination.
