Preoperative MRI findings. (a) MRI brain, T1WI sagittal view. Demonstrates cerebellar ectopia, measuring approximately 5.9 mm with crowding within the foramen magnum. (b) MRI brain, T2WI coronal view. Demonstrates prominent retrocerebellar cystic space. The differential diagnosis includes major cisterna magna versus an arachnoid cyst. (c) MRI cervicothoracic spine, T2WI sagittal view. Demonstrates 8 mm syrinx from C5 to T1-2. (d) MRI cervicothoracic spine, T2WI axial view at the level of C6-7

The patient is a 6-year-old male who was referred to a pediatric clinic for an incidentally found CM-I and cervicothoracic syrinx [Figure 1] identified during a preoperative workup prior to the surgical management of a progressive thoracolumbar kyphosis [Figure 2].
Spinal Imaging. (a) MRI thoracolumbar spine, sagittal view. (b) CT thoracolumbar spine, sagittal view. Both demonstrate severe gibbus deformity centered at L1 causing moderate to severe bony spinal canal stenosis

3-month postoperative MRI. (a) MRI cervicothoracic spine, T2 WI sagittal view. Demonstrates improvement in syrinx from C5 to T1-2. (b) MRI cervicothoracic spine, T2 WI axial view at the level of C6-7
