Borderline Intracranial Hypertension Manifesting as Chronic Fatigue Syndrome Treated by Venous Sinus Stenting.
Higgins, Nicholas, Pickard, John, Lever, Andrew · Journal of neurological surgery reports · 2015 · DOI
Quick Summary
This case study describes one woman with severe chronic fatigue syndrome (ME/CFS) who was found to have slightly elevated pressure inside her skull. Doctors discovered that blood vessels in her brain were narrowed, similar to a condition called idiopathic intracranial hypertension. When doctors placed stents (small tubes) to open these narrowed vessels, her fatigue symptoms dramatically improved and stayed better for at least 2 years.
Why It Matters
This study raises an intriguing hypothesis that a subset of ME/CFS patients may have undetected elevated intracranial pressure amenable to vascular intervention. It suggests a potential biological mechanism and therapeutic pathway for a condition often dismissed as psychosomatic, which could redirect clinical investigation and treatment approaches for severely affected patients.
Observed Findings
One 49-year-old woman with long-standing ME/CFS underwent intracranial pressure measurement showing borderline elevation.
Neuroimaging revealed narrowings (stenosis) at both transverse sinuses consistent with IIH.
Bilateral transverse sinus stenting resulted in major improvement in fatigue symptoms.
Symptom remission persisted for at least 2 years post-intervention with no regression.
Inferred Conclusions
Some ME/CFS cases may represent atypical presentations of intracranial hypertension with venous drainage obstruction.
Direct intracranial pressure measurement and advanced neuroimaging should be considered in ME/CFS patients with headache.
Venous sinus stenting may be a viable treatment for ME/CFS patients with documented elevated intracranial pressure and sinus stenosis.
Remaining Questions
How common are transverse sinus stenosis and elevated intracranial pressure in unselected ME/CFS populations?
What proportion of ME/CFS patients would benefit from venous intervention versus other treatments?
What mechanisms cause the transverse sinus narrowing and its association with fatigue symptoms?
What This Study Does Not Prove
This single case report cannot establish that elevated intracranial pressure causes ME/CFS or that it applies to all or even most ME/CFS patients. The dramatic response in one patient does not prove causation, and the improvement could reflect placebo effect, natural variation, or other unmeasured factors. Larger controlled studies are needed before recommending invasive procedures for ME/CFS populations.
