There are many non-neoplastic intramedullary lesions that mimic intramedullary neoplasm. They are consisted of demyelination, granulomatous disease, infections, radiation myelopathy, vascular lesions, and syringomyelia. In this report, the authors described its differential diagnosis in clinical and neuroradiological findings. Furthermore, we mentioned its surgical approach for several non-neoplastic lesions. Syringomyelia and spinal AV fistula are both good candidate of surgical treatments. We would like to stress that good cooperation between neurologist, neuroradiologist, and neurosurgeon is important to differentiate non-neoplastic lesions and surgical biopsy is final procedure to confirm their pathology.
