Summary
Spontaneous cerebrospinal fluid-venous fistulas (CVFs) typically lack trauma history. This study introduces posttraumatic pseudomeningoceles as a novel potential cause for CVFs, expanding understanding of their development.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Cerebrospinal fluid-venous fistulas (CVFs) are a primary cause of spontaneous intracranial hypotension.
- CVFs usually arise spontaneously, without significant preceding trauma or iatrogenic factors.
- The pathogenesis and predisposing factors for spontaneous CVFs remain poorly understood.
Purpose of the Study:
- To investigate a potential novel etiology for CVFs.
- To describe CVFs arising in association with posttraumatic pseudomeningoceles.
Main Methods:
- Case report presentation.
- Review of spinal imaging findings in patients with CVFs.
Main Results:
- Two cases of CVFs associated with posttraumatic pseudomeningoceles are presented.
- This association has not been previously reported in the literature.
- Most spontaneous CVFs originate from atraumatic meningeal diverticula.
Conclusions:
- Posttraumatic pseudomeningoceles may represent a novel cause of CVFs.
- This finding potentially expands the known pathogenesis of CVFs.
- Further research is needed to confirm this association and its implications.
