Illustratioin Spontaneous Intracranial Hypotension — Bildlegende aus Frontiers in Neurology: „Overview of factors contributing to internal SIH. Predisposing factors are (A) low CSF outflow resistance (Rout), low intracranial venous pressure (Pss) and (B) low intracranial CSF volume. The main pathophysiological factor is increased spinal compliance due to (C) meningeal diverticula, dural tears with prolapsing arachnoid around meningeal diverticula or (D) increased distensibility of the dura mater (I = normal distensibility, II = increased distensibility). A combination of these factors can lead to a pathological cranial-to-spinal CSF shift causing brain sagging (B) and orthostatic symptoms without CSF leakage.“
