Abstract | BACKGROUND:
Spontaneous intracranial hypotension (SIH) is an increasingly described entity, with over 70 cases reported in the literature. The classic triad includes orthostatic headache, diffuse pachymeningeal enhancement on magnetic resonance imaging (MRI) with gadolinium, and low cerebrospinal fluid pressure (CSF) in the lateral decubitus (< 60 mm H₂O) and sitting positions. METHOD: We present four rare clinical presentations of SIH, two of which have not been previously described in the literature, to the best of our knowledge. RESULTS: CONCLUSION: Although uncommon clinical presentations, all four cases of intracranial hypotension were spontaneous, demonstrated diagnostic MRI findings, and responded favorably to blood patches or saline injections.
