Dorsal CSF leak variants and mid-thoracic predilection characterized in SIH patients

Two variants of spontaneous dorsal spinal CSF leaks were identified: 75% of patients had a simple linear dural tear, while 25% had pseudomeningoceles. Half of all leaks were located in the mid-thoracic spine, and digital subtraction myelography findings were concordant with surg…

• Extensive extradural CSF collections spanning many levels were present in all patients with a linear dural tear.
• The study is limited by a small sample size from a single quaternary referral center, which may limit generalizability.
