An interesting trivia related to CSF leaks is that actor George Clooney suffered one after a blow to the head while filming a torture scene in the 2005 movie "Syriana".
The take-home message is that not all runny noses are due to allergies, especially if it is continuous and only occurs on one side.
Typically, if CSF leak is suspected, a red-top tube is provided to the patient to collect some of this fluid. The specimen is than sent to be tested for beta2-transferrin which is ONLY found in CSF.
A high resolution CT scan of the sinuses and/or temporal bone is also obtained to localize WHERE the abnormal leak is coming from.
What type of surgery is performed utterly depends on where the leak is coming from... if truly sinus in origin, endoscopic sinus surgery is performed. If coming from the bone around the ear, a middle cranial fossa approach to fixing the leak is performed.
