BACKGROUND AND IMPORTANCE
Intramedullary spinal cord metastases (ISCMs) are rare and no cases of ISCM from an adenoid cystic carcinoma (ACC) of the external auditory canal (EAC) have been reported.
CLINICAL PRESENTATION
We report a 54-year old man complaining backpain and worsening myelopathy. He had an ACC of the EAC resected years prior. A spinal MRI demonstrated a contrast-enhancing intramedullary lesion within the conus medullaris. The histopathological diagnosis of the patient was consistent with the patient's primary cancer. At 3 months follow-up, the neurological condition of the patient was unchanged.
CONCLUSIONS
This is the first reported case of ISCM from a primary ACC of the EAC.
背景与重要性
脊髓髓内转移瘤（ISCMs）较为罕见，且外耳道腺样囊性癌（ACC）导致的ISCM病例尚未见报道。
临床表现
我们报告一名54岁男性，主诉背痛且脊髓病加重。他数年前曾接受外耳道ACC切除术。脊髓磁共振成像（MRI）显示圆锥内有一强化的髓内病变。患者的组织病理学诊断与原发癌相符。随访3个月时，患者神经状况无变化。
结论
这是首例报道的由外耳道原发性ACC导致的ISCM病例。
