Characteristics and clinical pathologic analysis of computed tomography, magnetic resonance imaging in the lymphoma of head and neck / 白血病·淋巴瘤

ABSTRACT

Objective To explore the imaging and clinical pathological features of extranoda and intranoda lymphoma in head and neck characterized by computed tomography (CT) and magnetic resonance imaging (MRI).Methods 46 malignant lymphoma patients were confirmed by surgery and pathology.The CT and MR images data were reviewed and analyzed in comparison with surgical and pathological results.Diagnostic value of the CT and MRI findings were analyzed. Results The subjects enrolled in this study including 38 cases of non-Hodgkin lymphoma(NHL)and 8 cases of Hodgkin Lymphoma(HL).The pathological sites of extranodal lymphomas (45.65 ％,21/46) included nasal (10 cases),Waldeyer ring (7 cases),throat (2 cases),Thyroid(1 case) and parotid (1 case).The lymph nodes metastases in the neck were observed in 13 cases of Extranodal lymphomas.Intranodal lymphoma in neck (54.35 ％,25/46) involved all district lymph nodes especially Ⅱ-Ⅳ districts. According to the Ann Arbor staging,14 cases were Ⅰ staging, 19 cases Ⅱ staging,none Ⅲ staging,Ⅳ staging 13 cases.According tumor form,21 cases were multinodulars,12 cases mass type, 11 cases diffuse swelling type, 2 cases ulcer or necrotic type. Conclusion CT and MR images might indicate the location, morphology, surrounding tissue and lymph nodes metastases of malignant lymphoma in head and neck.Great value in clinical diagnosis and treatment is observed.
