A case of idiopathic low CSF pressure headache presenting as cough headache.

Idiopathic low cerebrospinal fluid (CSF) pressure headache is considered to be one that worsens within 15 min of sitting-up or standing-up, accompanied by at least one of the following: neck stiffness, tinnitus, hypacusia, photophobia and nausea. Several reports suggest that a substantial number of idiopathic low CSF pressure cases do not present typical clinical symptoms and that a considerable clinical variability exists. We report the case of an idiopathic low CSF pressure presenting as a cough headache.
