We observed 2 cases of malignant melanoma arising from the eustachian tube with MR imaging. In this region, we explored further characteristics of primary mucosal melanoma. We discuss the value of using MR imaging to diagnose and treat patients with melanoma in the eustachian tube. In addition, we introduce the key points to differentiate melanoma from some common diseases in the region.
我们通过磁共振成像(MR)观察到2例起源于咽鼓管的恶性黑色素瘤。在该区域,我们进一步探究了原发性黏膜黑色素瘤的特征。我们讨论了利用MR成像诊断和治疗咽鼓管黑色素瘤患者的价值。此外,我们介绍了将黑色素瘤与该区域一些常见疾病相鉴别的关键点。
