Esthesioneuroblastoma (ENB) is a malignant neoplasm of the olfactory epithelium. Metastasis of ENBs to retropharyngeal lymph nodes is an important finding on imaging examinations that alters staging and treatment. A total of 17 cases of ENB from 3 institutions were evaluated. The CT and MR imaging findings from the cases of 4 patients with ENB with retropharyngeal metastatic disease are reviewed. The vector of spread, staging, and treatment implications are discussed.
嗅神经母细胞瘤（ENB）是一种起源于嗅上皮的恶性肿瘤。ENB转移至咽后淋巴结是影像学检查中的一项重要发现，它会改变分期并影响治疗方案。我们对来自3家机构的17例ENB病例进行了评估。回顾了4例伴有咽后转移的ENB患者的CT和MR成像表现。并讨论了其扩散途径、分期及对治疗的意义。
