Syringomyelia caused by intrathecal remnants of oil-based contrast medium.

Oily contrast medium had been in use since the early 19th century as a radiographic agent for detecting spinal lesions and spinal cord tumors until the late 20th century. At that point computed tomography scanning and magnetic resonance imaging, or other hydrophilic contrast medium substituted for it. Adverse effects of oil-based dye, both acute and chronic, had been reported since the middle of the 20th century.

[Peri-operative treatment with botulinum A toxin prior to posterior cervical decompression in a case with cervical spondylosis caused by spasmodic torticollis secondary to cerebral palsy].

Patients with spasmodic torticollis secondary to athetoid cerebral palsy may develop symptomatic degenerative cervical disc disease or spondylosis. In these cases, peri-operative stabilization of the cervical spine is considered to be difficult and recurrence occurs frequently. We reported a case with cervical spondylosis induced by athetoid cerebral palsy.
