Intramedullary spinal cord metastasis from esophageal squamous cell carcinoma: case report and literature review.

Background: Intramedullary spinal cord metastasis (ISCM) of malignant tumors rarely happens. To the best of our knowledge, only five cases of ISCM from esophageal cancer have been reported in literature. We here report the sixth descripted case of ISCM from esophageal cancer.

Case Presentation: A 68-year-old male presented with weakness of right limbs and localized neck pain two years after diagnosed esophageal squamous cell carcinoma. The gadolinium enhanced Magnetic resonance imaging (MRI) of cervical spine showed a mixed-intense intramedullary tumor with typical more intense thin rim of peripheral enhancement in C4-C5. The patient died fifteen days after diagnosis of irreversible respiratory and circulatory failures. An autopsy was refused by his family.

Conclusions: This case highlights the importance of gadolinium enhanced MRI for diagnosis in ISCM. We believe that early diagnosis and surgery for selected patients shows helpfulness to save their neurologic function and improve quality of life.
