目的 评价头颈部非霍奇金淋巴瘤(nonHodgkinlymphoma,NHL)的CT表现特点,为临床诊疗提供可靠依据。方法 将36例NHL病灶分为颈淋巴结内组和淋巴结外组,并观察其CT形态、密度和边缘。结果 结外NHL病变共39灶(31例),依次见于Waldeyer环(11灶)、上颌(8灶)、颌面间隙(7灶)、腮腺(6灶)和头颈其他部(7灶)。病变形态有肿块和粘膜异常增厚之分。结内NHL病变共累及16侧颈区淋巴结。结外NHL伴结内NHL者共10侧颈区。结论 头颈部结外NHL的CT表现特点为多发边缘不光滑的软组织实性肿块;颈淋巴结内NHL多有坏死和边缘增强,淋巴结融合肿块则于单发结内NHL中多见
Objective To evaluate the CT features of non-Hodgkin lymphoma (NHL) in head and neck and provide a reliable basis for clinical diagnosis and treatment. Methods Thirty-six NHL lesions were divided into the intracervical lymph node group and the external lymph node group, and their CT morphology, density and margins were observed. Results Extranodal NHL lesions totaled 39 lesions (31 cases), which were found in Waldeyer ring (11 lesions), maxillary (8 lesions), maxillofacial gap (7 lesions), parotid gland (6 lesions) and other head and neck (7 lesions). Lesion morphology and abnormal thickening of the mucosal points. Intra-nodal NHL lesions involved 16 cervical lymph nodes. There were a total of 10 cervical areas in the extranodal NHL with NHL. Conclusion The CT features of extranodal NHL in the head and neck are characterized by multiple solid soft masses with marginal borders; necrosis and marginal enhancement of NHL in cervical lymph nodes are common, and lymph node fusion masses are more common in single intranodal NHL.
