A Case of Intracranial Hypotension after Horse Riding

Facial Nerve Paralysis Due to Spontaneous Intracranial Hypotension

“…Other similar cases of SIH have been reported in patients after doing heavy lifting, 8 racket sports, 9 and horseback riding. 10 Pachymeningeal enhancement and subdural fluid collection among others are seen on MRI and evidence of a CSF leak may or may not be seen on myelography or cisternography. Proposed mechanisms for these cranial nerve palsies have included traction on nerves due to downward displacement of intracranial contents, mechanical irritation/compression, and vascular congestion of the nerve, 1,4,6 but the actual pathophysiology remains unclear.…”
