Resolution of pachymeningeal enhancement is a radiographic marker for effective treatment of spontaneous intracranial hypotension: patient series.

Key Points

To investigate the relationship between pachymeningeal enhancement and treatment efficacy in spontaneous intracranial hypotension (SIH).
Analyzed MRI scans for diffuse pachymeningeal enhancement in SIH patients.
Assessed resolution of SIH post-treatment using MRI findings.
Evaluated correlation between radiographic markers and clinical outcomes.
Pachymeningeal enhancement often resolves before clinical symptoms improve.
MRI findings can indicate effective treatment for SIH.
Radiographic assessment may enhance post-treatment evaluations.

Abstract

Diffuse pachymeningeal enhancement is a reliable marker for resolution SIH and often predates clinical resolution. Therefore, the authors propose that assessing for this characteristic with contrasted-brain MRI may assist in the posttreatment evaluation of patients with SIH. https://thejns.org/doi/10.3171/CASE25819.
