Spontaneous spinal CSF leakage with the development of intracranial hypotension is a well-described entity. Cerebrospinal fluid leaks, mostly from the thoracic spine, are the major cause of spontaneous intracranial hypotension (SIH). Conservative treatment options include hydration, oral caffeine, and epidural blood patching. Alternatively, open surgical correction of meningeal diverticula is a therapeutic option. The authors describe 4 cases of spontaneous spinal CSF leakage producing symptoms of intracranial hypotension. All patients had multiple spinal diverticula with an identified leaking level. The patients were treated using a minimally invasive approach via surgical correction of the meningeal diverticulum.
Abbreviation used in this paper: SIH = spontaneous intracranial hypotension.
