case_images: (A) Preoperative sagittal T1-weighted MRI of the brain shows Chiari 1 malformation
  (cerebellar tonsils displaced 13 mm below the foramen magnum) and hydrocephalus. (B)
  Preoperative axial T2-weighted MRI of the brain shows hydrocephalus. (C) Preoperative
  sagittal T2-weighted MRI of the C- and T-spine shows cord edema throughout the cervical
  spine, a syrinx from C3-4 extending inferiorly to T8-T9, and displaced peripheral
  parenchymal thinning extending to T8-T9.

case_images: It was recommended to obtain neuraxis imaging (Figure 1) that demonstrated crowding and inferior displacement of cerebellar tonsils 13 mm below the foramen magnum.
case_images: (A) sagittal T1-weighted MRI of the brain taken 2 months after surgery shows adequate
  hindbrain decompression and resolution of hydrocephalus. (B) Axial T2-weighted MRI of
  the brain taken 2 months after surgery shows resolution of hydrocephalus. (C) Sagittal
  T2-weighted MRI of the C- and T-spine taken 2 months after surgery demonstrate that
  holocord syrinx has decreased in size.

case_images: Follow-up MRIs taken 2 months after surgery (Figure 2) showed adequate decompression, resolution of hydrocephalus, and decreased size of syrinx.
