摘要:
目的：探讨鼻黏膜原发性恶性黑色素瘤的 MRI/MSCT 的影像特点，提高诊断正确率。方法：搜集广西梧州市红十字会医院 2012 年 1 月至 2018 年 5 月经病理证实的 17 例鼻黏膜原发性恶性黑色素瘤，MSCT 平扫＋增强扫描 6 例；MSCT 平扫＋MRI 扫描 11 例，分析其影像表现特点。结果：17 例患者 MSCT 平扫中，位于鼻腔 12 例，鼻咽 2 例，鼻窦 3 例；均呈膨胀性生长，形态不规则；肿物密度多呈不均匀的软组织影，未见钙化，4 例病灶内见少量出血、坏死；侵犯周围组织 15 例，其中10 例出现骨质吸收、破坏；出现淋巴结转移 5 例。11 例 MRI 检查中 T1WI 呈高信号，T2WI 呈低信号表现 3 例；T2WI 呈等、稍低信号，T1WI 呈等、稍高信号的 2 例，T2WI、T1WI 均呈稍高、高、等混杂信号 6 例，DWI 均呈高信号。MRI 及 MSCT 增强扫描明显不均匀强化 6 例，轻中度不均匀强化 11 例。结论：鼻黏膜原发性恶性黑色素瘤在 MRI 表现有一定的特征，MSCT虽无明显特征，但在病灶对骨质破坏表现上有重要诊断价值，两者应用可提高诊断正确率，为临床分期及治疗提供帮助。
Abstract:
Objective: To investigate the imaging features of primary malignant melanoma of nasal mucosa on MRI/MSCT and toimprove the diagnostic accuracy.Methods: Seventeen cases of primary malignant melanoma of nasal mucosa confirmed by pathology fromJanuary 2012 to May 2018 in Wuzhou Red Cross Hospital of Guangxi were collected, which six cases were performed MSCT plain scanand enhanced scan, and 11 cases were performed MSCT plain scan and MRI scan. The imaging features were analyzed. Results: Among 17patients undergoing MSCT examination, 12 were located in nasal cavity, 2 in nasopharynx and 3 in sinus. All showed expansion growth,irregular shape. The mass density was mostly uneven soft tissue shadow, no calcification was observed, and a small amount of bleeding andnecrosis were observed in 4 cases. There were 15 cases of invasion of surrounding tissues, among which 10 cases showed bone absorptionand destruction. Lymph node metastasis occurred in 5 cases.Among the eleven patients with MRI examination, 3 cases showedhyperintense on T1WI and hypointensity on T2WI, 2 cases showed isointensity or little hyerintense on T2WI and isointensity or littlehyperintense on T1WI, 6 cases showed heterogeneous on T1WI and T2WI. AII the cases showed high signal on DWI. 6 cases demonstratedobvious heterogeneous enhancement and 11 cases showed mild heterogeneous enhancement on MRI and MSCT enhanced image.Conclusion: The primary malignant melanoma of nasal mucosa display typical signs on MRI imaging, not specific on MSCT imaging, butMSCT has important diagnostic value in the lesion to bone destruction. Both of them can improve the diagnostic accuracy and provide helpfor clinical staging and treatment.
