The Spatial Relationship between Spinal Osteoarthritis and CSF Venous Fistulas in Patients with Spontaneous Intracranial Hypotension

Three patients with osteoarthritis at the level of their CVFs. Upper row, A 66-year-old woman with intracranial hypotension and a right T7–T8 CVF. A, Midline sagittal CT image from dynamic myelography demonstrates anterior endplate osteophytes clustered from T4–T5 through T9–T10 (dashed arrows) and disc protrusions at T6–T7, T7–T8, and T8–T9. B, Paramidline sagittal CT image from dynamic myelography demonstrates a CVF arising from the right T7–T8 neural foramen (solid arrows). Middle row, A 61-year-old man with intracranial hypotension and a left T11–T12 CVF. C, Oblique coronal MIP CT image from dynamic myelography demonstrates a CVF arising from a meningeal diverticulum at T11–T12 on the left (arrow). D, Axial image from DCTM demonstrates left T11–T12 facet arthrosis (dashed arrow) and a corresponding CVF (solid arrow). Lower row. A 61-year-old man with intracranial hypotension and a right T10–T11 CVF, E, Axial CT image from dynamic myelography demonstrates a disc bulge and endplate osteophytes (dashed arrows) and a CVF (solid arrow) at the T10–T11 level. F, Sagittal paramidline CT image demonstrates disc bulging with lateral endplate osteophytes at T10–T11 (dashed arrow) and an adjacent CVF (solid arrow).
