case_images: T2 signal hyperintense area, just to the right of midline, that extended throughout the length of the central cervical spinal cord, consistent with an expanding syrinx [Figure 1].

case_images: Thoracic MRI showed the syrinx extended throughout the thoracic spinal cord as well [Figure 2].
case_images: Sagittal T2 cervical spine magnetic resonance imaging 8 months after parathyroidectomy showing cranial expansion of cord signal abnormality into the brain stem. Yellow arrow indicates syrinx in brain stem.

case_images: Cervical MRI was repeated and showed rostral expansion of the syrinx into the brain stem [Figures 3 and 4].
case_images: Axial T2 cervical spine magnetic resonance imaging 8 months after parathyroidectomy showing cranial expansion of cord signal abnormality into the brain stem. Yellow arrow indicates syrinx in brain stem.

case_images: Cervical MRI was repeated and showed rostral expansion of the syrinx into the brain stem [Figures 3 and 4].
case_images: Sagittal T2 cervical spine magnetic resonance imaging 4 months after syringo-subarachnoid shunt placement demonstrating improvement in syringomyelia.

case_images: Cervical MRI 4 months after surgery (S+14 months) showed dramatic reduction in syrinx size, with only a small residual fluid collection, which confirmed that the shunt was patent and functioning [Figure 5].
case_images: Sagittal T2 thoracic spine magnetic resonance imaging 4 months after syringo-subarachnoid shunt placement demonstrating persistent syringomyelia.

case_images: However, thoracic MRI showed possible persistent syringomyelia with slight enlargement compared to previous, which was significantly limited due to hardware artifact [Figure 6].
