A case report of an intramedullary cervical teratoma in an adult patient with cervical spondylotic radiculopathy.

Spinal cord teratomas are rare. There are few reports of teratomas affecting the cervical spine and their association with spondylotic radiculopathy has not been described. A 59-year-old woman with history of fecal incontinence attended with cervical radicular pain radiating to upper limbs. Physical examination showed distal muscle hypotrophy and abolishment of bicipital, tricipital, and brachioradialis reflexes of the right arm, preserving proximal strength. Also, hiporreflexia and loss of proprioception in the right lower limb was observed. Magnetic resonance imaging showed an intramedullary mass at C7-T1, accompanied by intervertebral disk protrusions and dural sac compressions at the same level. One-stage posterior-anterior operative approach for tumor resection, decompression of the radiculopathy and replacement of intervertebral discs was performed. The histopathological diagnosis was for a mature teratoma. We described the first case of an intramedullary cervical teratoma associated with radiculopathy in an adult, providing evidence of rare long-lasting teratomas affecting the cervical spine.
