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].

Thoracic MRI showed the syrinx extended throughout the thoracic spinal cord as well [Figure 2].
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.

Cervical MRI was repeated and showed rostral expansion of the syrinx into the brain stem [Figures 3 and 4].

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].

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