目的探讨鼻腔NK/T细胞淋巴瘤的CT影像特点。方法对13例经手术和病理证实的鼻腔NK-T细胞淋巴瘤患者进行CT平扫检查,其中9例进行增强扫描。结果 CT显示病变呈弥漫性生长,形态不规则,主要位于鼻腔前部和鼻前庭,堵塞鼻道和副鼻窦开口,与鼻甲和鼻中隔分界不清。平扫多数病变密度均匀,部分病变内有低密度区,部分有鼻甲和上颌窦骨壁侵蚀性骨质破坏缺损改变。增强扫描病变均匀中度强化,平扫低密度坏死区无强化。结论 CT能显示NK/T细胞淋巴瘤的一些影像表现特性及肿瘤周围侵犯范围,有助于提高临床诊断的正确性。
Objective To investigate the CT features of nasal NK / T cell lymphoma. Methods Thirteen patients with nasal NK-T cell lymphoma confirmed by surgery and pathology were examined by CT plain scan. Nine patients underwent enhanced CT scan. Results CT showed diffuse growth, irregular shape, mainly in the front of the nasal cavity and nasal vestibule, blocking the opening of the nasal passages and paranasal sinus, turbinate and nasal septum demarcation. Most of the lesions showed even density, some of the lesions had low density area, and some of them had alteration of the erosive bone destruction defect. Enhanced scanning lesion was moderately enhanced, plain low density necrosis area without strengthening. Conclusion CT can show some imaging features of NK / T-cell lymphoma and the extent of tumor encroachment, which can help to improve the correctness of clinical diagnosis.
