目的:探讨头颈部咽淋巴环外结外淋巴瘤的CT及MRI表现,提高其诊断准确性。方法:经手术或病理证实的11例头颈部咽淋巴环外结外淋巴瘤患者术前行CT及MRI检查,对该组影像资料回顾性分析。结果:根据肿瘤形态分为3型,其中单发肿块型6例,弥漫肿胀型1例,溃疡坏死型4例。结论:头颈部咽淋巴环外结外淋巴瘤的临床病理及CT及MRI影像表现有一定特征性,影像检查可以显示病变形态、范围及淋巴结转移,结合临床特点对头颈部咽淋巴环外结外淋巴瘤的诊断、分期及指导治疗有一定价值。
Objective: To investigate the CT and MRI findings of extrahepatic lymphoma of the pharyngeal lymph nodes of head and neck, and to improve the diagnostic accuracy. Methods: 11 cases of extranodal lymph nodes outside the head and neck pharyngeal lymph nodes confirmed by surgery or pathology were examined by CT and MRI preoperatively. The imaging data of the patients were retrospectively analyzed. Results: The tumors were divided into 3 types according to the tumor morphology, including 6 cases of solitary mass type, 1 case of diffuse swelling type and 4 cases of ulcer necrosis type. Conclusion: The clinical pathology, CT and MRI findings of extrahepatic lymphoma of the head and neck extrahepatic lymph nodes of the head and neck have some characteristics. The imaging examination can show the morphology, extent and lymph node metastasis. Combined with clinical features, Foreign lymphoma diagnosis, staging and guidance and treatment have some value.
