Spontaneous intracranial hypotension caused by cervical CSF fistulae mimicking subarachnoid haemorrhage – a case report

Abstract

We describe an unusual and rarely documented site of SIH supported by clear radiological evidence: a case of spontaneous cerebrospinal fluid (CSF) fistulae involving the C7 and C8 nerve root sheaths, presenting with sudden onset headache and requiring surgical intervention to seal the leaks. Investigations confirmed the leaks and the typical MRI findings of meningeal enhancement, which were resolved after surgery.
