Background and Objective:The tonsils are the most commonly involved primary part of non-Hodgkin's lymphoma(NHL) of the head and neck,which usually happens in the Waldeyer's ring.Our study describes the features of computed tomography on enlarged tonsils as a first symptom of NHL and the characteristics of the involved cervical lymph nodes.Methods:A retrospective review was performed on 130 patients with primary extranodal lymphomas of the head and neck over 16 years.Of them 22 untreated patients showed tonsil lesions as a first symptom.Results:Bilateral enlarged tonsils were involved in 13 patients,and unilateral lesions were in 9 patients.The lesions in 20 patients appeared mass-like,while 2 patients had diffuse thickening.There were 8 patients with simultaneous invasion of the nasopharynx,soft palate,and epiglottis.Of the 19 patients that underwent enhanced CT scans,15 patients demonstrated slight homogeneous enhancement,4 with crannied or a patch of low density,and 1 with ring-like enhancement.All 22 patients appeared to have cervical lymph nodes involvement.The upper groups of cervical lymph nodes were involved bilaterally in 13 patients,unilaterally in 9 patients.The middle groups were involved bilaterally in 7 patients,unilaterally in 10 patients.The lower groups were involved bilaterally in 2 patients,and unilaterally in 5 patients.After contrast administration,lymph nodes showed homogeneous density and slight enhancement in 11 patients,heterogeneous enhancement with necrosis and cystic changes in 6 patients,and ring-like enhancement in 2 patients.Conclusions:Bilateral involvement,homogeneous density,and slight enhancement are characteristics of tonsil involvement of non-Hodgkin's lymphoma.Bilateral upper groups of cervical lymph nodes are the most frequently involved lymph nodes,which are often shown with homogeneous density and slight enhancement.
