Parasagittal subdural space: a novel quantitative marker of spontaneous intracranial hypotension syndrome-induced chronic subdural hematoma.

ABSTRACT:

Background

Spontaneous intracranial hypotension syndrome (SIH)-induced chronic subdural hematoma (CSDH) often presents with orthostatic headaches but is frequently misdiagnosed, leading to inappropriate treatments like fatal hematoma drainage instead of epidural blood patches. In clinical practice, reliable and quantitative diagnostic criteria for this condition are lacking. This study uses initial CT scans to identify novel radiographic markers for accurately diagnosing SIH-induced CSDH.

Methods

We retrospectively reviewed 310 consecutives hospitalized CSDH cases from January 2008 to May 2023. Among these, 54 were bilateral, with 11 induced by SIH; two secondary intracranial hypotension cases were excluded. We analyzed nine primary SIH-induced cases, comparing clinical and
