Cervicothoracic spine duplication: a 10‑year follow up of a neurological intact boy
Özet
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 frst 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 classifed 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 unclassifed and cervicothoracic duplication level without neurological defcitis.
Treatment of SCM was based on removal of splitting fbrous/osseous process. Neurologic intact spine duplication could be
followed up without surgical intervention.
