Analysis Of Clinical Features Of Primary Extranodal Non-Hodgkin’s Lymphoma Of The Head And Neck

Objective: To retrospectively analyze the clinical and imaging characteristics of patients with primary extranodal non-Hodgkin’s lymphoma in the head and neck,to determine whether there is specificity,and whether there is any correlation between pathological types and imaging characteristics.Guide clinical work and improve the level of diagnosis and treatment.Methods: Collected from January 2015 to December 2020 in the First Affiliated Hospital of Xinjiang Medical University,91 patients with primary extranodal non-Hodgkin’s lymphoma of the head and neck who were diagnosed pathologically with relatively complete clinical data.Retrospective analysis of its clinical features,imaging features,etc.Results: The primary site in this study was the pharyngeal lymphatic ring the most common,and the rest were nasal cavity,salivary glands,thyroid,sinuses and oral cavity,larynx and eyes in order.51 to 60 years old and 71 to 80 years old are two high-incidence age groups,and the male to female ratio is 1.275:1.28 cases of T/NK cell origin,accounting for 30.77%,mostly occur in the nasal cavity,mainly diffuse infiltrating or mixed type,imaging manifestations are irregular lesions,unclear borders,ununiform density,and moderate after enhancementSignificant enhancement;63 cases of B-cell origin,accounting for 69.23%,mostly occurred in the pharyngeal lymphatic ring,mainly in the form of masses.The imaging manifestations of the lesions were relatively regular,with clear boundaries with surrounding tissues,uniform density,and moderate-to-obvious enhancement.Conclusion:The imaging features of primary extranodal non-Hodgkin’s lymphoma of the head and neck are specific,and different pathological types are correlated with imaging findings,which can provide a basis for preliminary diagnosis.
