目的：探讨咽淋巴环非霍奇金淋巴瘤的ＣＴ诊断价值。方法：对７６例经病理证实的咽淋巴环非霍奇金淋巴瘤的冠状及横断平扫和增强扫描的ＣＴ影像学特征进行回顾性分析。结果：除鼻咽３５例、舌根部２例单发ＮＨＬ外，其余３９例多为灶性。其 ＣＴ影像特征为多病灶跨越性生长，平扫 ＣＴ值 ３５～５０ ＨＵ，增强后则全部 ６０－９０ ＨＵ，且密度均匀强化。骨质破坏较少，颈淋巴结数量多，强化明显。结论：ＣＴ检查对ＮＨＬ的临床分期及确定咽淋巴环病灶的范围、大小具有重要作用。
Objective: To investigate the CT diagnosis of pharyngeal lymph node non-Hodgkin’s lymphoma. Methods: The CT features of 76 cases of pathologically confirmed non-Hodgkin’s lymphoma of the pharyngeal lymph nodes were analyzed retrospectively. Results: In addition to nasopharyngeal 35 cases, 2 cases of tongue base of single NHL, the remaining 39 cases were mostly focal. The features of CT images were multi-lesion spans growing, CT scan value 35 ~ 50 HU, all the enhanced 60-90 HU, and the density of uniform enhancement. Less bone destruction, the number of cervical lymph nodes, enhanced significantly. Conclusion: The CT examination plays an important role in the clinical stage of NHL and the scope and size of the focal lymphadenopathy.
