Abstract: Objective To investigate the CT findings of histocyticnecrotizing lymphadenitis(HNL)in the neck.Methods CT data of 10 patients with pathologically confirmed HNL in the neck were retrospectively analyzed,7 males and 3 females,aged from 4 to 75 years old(median age 26 years old).Nine patients had plain CT scans and 5 of them had contrast scans.One case had only contrast CT scan.Results Totally,127 lymph nodes were identified in the neck,mainly located in the area of Ⅱ,Ⅲ,Ⅳ and Ⅴ.The maximum diameter of the involved lymph nodes ranged from 0.5-3.6 cm,1.3 cm in average.One hundred and eight lymph nodes were homogeneous and 8 were heterogeneous in plain CT images.Seventy nine lymph nodes had homogeneous enhancement and 27 had heterogeneous enhancement One hundred and ten lymph nodes had unclear margins and the surrounding fat was blurred.Conclusion CT findings of HNL of the neck are variable and non-specific.Clinical findings and laboratory examination may be helpful for the diagnosis and differential diagnosis.
