Bilateral subdural fluid collections associated with spontaneous intracranial hypotension

Takeaway

  • Bilateral subdural fluid collections attributed to spontaneous intracranial hypotension (SIH) is associated with sagittal sagging, pseudo-subarachnoid hemorrhage (pseudo-SAH), small volumes of subdural fluid (≤22.08 mm) and age ≤55 years.

Why this matters

    SIH is rare and its characteristics are not well defined; this study identifies key features of SIH that could guide physicians in its diagnosis and treatment.
