Intracranial hypotension (IH), often resulting from a cerebrospinal fluid (CSF) leak, is a
notable cause of secondary headaches. Diagnosing IH through clinical assessment and
neuroimaging can be challenging. Orthostatic headache (OH), characterized by neck
stiffness, nausea, dizziness, phonophobia, and photophobia, is a key symptom of CSF leakage,
which may stem from a variety of causes, including falling, surgery, CSF studies, or arachnoid
diverticula. This study presents two OH patients with IH who were incidentally found to have
an underlying meningocele.
