Cervicothoracic spine duplication: a 10-year follow up of a neurological intact boy

Eur Spine J. 2018 Jul;27(Suppl 3):489-493. doi: 10.1007/s00586-018-5524-1. Epub 2018 Feb 17.


Purpose: Spine duplication is a very rare condition with the literature being composed of only case reports. All previously reported cases were thoracolumbar spine duplications. Here, we report cervicothoracic spine duplication in a neurological intact male. According to our knowledge, it is the first case in the literature of cervicothoracic spine duplication.

Clinical presentation: A 3-year-old patient presented to a primary physician with a complaint of short stature. He was referred to our department with suspected spinal deformity. Computerized tomography imaging revealed anterior bony structure duplication and posterior dysmorphic elements at the C5-T9 levels. Magnetic resonance imaging revealed a syrinx cavity which splits cord at the duplication level and the relation of the syrinx with posterior mediastinum through anterior bone defect. He was followed up for 10 years.

Conclusion: In the literature, spine duplication has been classified as a severe form of split cord malformation because of the concurrence of bone duplication with split spinal cord malformation (SCM). This case presents a distinct form of SCM which shows non-duplicated dural tube as unclassified and cervicothoracic duplication level without neurological deficitis. Treatment of SCM was based on removal of splitting fibrous/osseous process. Neurologic intact spine duplication could be followed up without surgical intervention.
