Summary

Spontaneous intracranial hypotension (SIH) causes disabling headaches due to cerebrospinal fluid (CSF) leaks, often from the spine. Epidural blood patches are a primary treatment, with surgery as an option if patches fail.

Area of Science:

  • Neurology
  • Neurosurgery
  • Radiology

Background:

  • Spontaneous intracranial hypotension (SIH) presents with orthostatic headaches and other neurological symptoms.
  • It is caused by cerebrospinal fluid (CSF) leaks, predominantly spinal.
  • Low CSF pressure is characteristic, though normal pressures can occur.

Purpose of the Study:

  • To summarize the clinical presentation, diagnostic findings, and treatment of SIH.
  • To highlight the common causes and locations of CSF leaks in SIH.
  • To review current management strategies for SIH.

Main Methods:

  • Review of clinical manifestations and diagnostic imaging (MRI, radioisotope cisternography).
  • Analysis of cerebrospinal fluid (CSF) pressure measurements.
  • Evaluation of treatment outcomes for epidural blood patches and surgery.

Main Results:

  • SIH symptoms include orthostatic headaches, neck pain, nausea, and visual disturbances.
  • Spinal CSF leaks are more common than skull base leaks.
  • MRI shows pachymeningeal enhancement and brain sagging; cisternography reveals CSF loss.
  • Epidural blood patch is the preferred treatment after conservative measures fail.

Conclusions:

  • SIH is a treatable condition often caused by spinal CSF leaks.
  • Prompt diagnosis and appropriate treatment, typically with epidural blood patches, are crucial.
  • Surgery offers a viable alternative when less invasive methods are unsuccessful.
