Article Figures & Data
Figures
- Fig 1.
Midsection sagittal T1-weighted image obtained without contrast material shows tonsillar descent almost to the arch of C1.
- Fig 2.
Axial postcontrast T1-weighted (A) and coronal postcontrast fast spoiled gradient-recalled echo (B) sequences show diffuse meningeal enhancement.
- Fig 3.
Axial thin-section CT images obtained through the C1-C2 (A) and the C2 (B) levels show epidural contrast material accumulation on the left side, with the possible site of leakage at the C1-C2 level.
- Fig 4.
Two axial CT images obtained with the patient in the prone position show needle placement in the left lateral epidural compartment at the upper C2 level (A) followed by administration of the blood patch; contrast material injected to confirm the epidural location is identified with mild flattening of the lateral thecal sac margin (B).
- Fig 5.
Midsection sagittal T1-weighted image obtained without contrast material shows resolution of the tonsillar descent. This measured less than 3 mm compared with the initial measurement of 8 mm. Compare with Fig 1.
- Fig 6.
Axial postcontrast T1-weighted (A) and coronal postcontrast fast spoiled gradient-recalled echo (B) sequences show resolution of the diffuse dural enhancement. Compare with Fig 2.
