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.

Intramedullary spinal tuberculomas constitute a small percentage of spinal tuberculosis. These, in combination with brain tuberculomas, are an uncommon manifestation of central nervous system (CNS) tuberculosis. This report details a unique case of a 32-year-old retroviral disease-positive male who presented with a two-month history of symmetrical quadriparesis and recent seizures.

Rationale: Ependymomas are commonly prevalent intramedullary neoplasms in adults, with hardly any cases of exophytic extramedullary ependymoma being reported. Meningiomas, on the contrary, are one of the most common intradural extramedullary (IDEM) tumors. However, the occurrence of both IDEM tumors simultaneously is extremely rare.

Intramedullary tumours (IMTs) are the least common neoplasms of the spinal canal. The majority of them are ependymomas and astrocytomas, the third commonest is haemangioblastoma, while other tumours of the spinal cord are relatively rare. This review presents on update on the imaging of spinal cord tumours.
