Thanks very much for your response. I appreciate your help and will ask my physician about the tests you mentioned.
First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.
It is very likely that the fluid filling the mastoid air cells in the area of the skull fracture is CSF. That being said, it may not be a problem, unless there is a persistent leak. If the leak only happened during the trauma, then that CSF and air (pneumocephalus-air in the head) will be re-adsorbed without any consequence. However-if you have a perisistent leak of CSF then this increases the chance that you will develop headaches, hearing problems and possible meningitis. Low pressure headaches (caused by CSF leaks) are worse with standing up, and get better with lying flat. Stiff neck, fever, altered mental status are all signs of meningitis. I would suggest a CT scan after the intrathecal injection of a tracer dye (CT cysternogram) or an MRI with CINE flow study to evaluate for CSF leak. If you develop any signs of meningitis, seek help immeadiately to be started on antibiotics.
I hope this has been helpful.
Hello Again,
I had a follow-up CT-scan done yesterday (now nearly three weeks after accident). It is still showing fluid in my mastoid. I am concerned about this. Without any noticeable external dripping, is there some way of identifying what that fluid is - to rule out CSF leak?
Thanks so much. I really need some help and direction on what to do.
Please, can you respond to one more thing - it is very important. My neurosurgeon says even if it is a small CSF leak we would probably not do anything about it anyway because the risks of surgery would outweigh the potential benefits. And he thinks that a small CSF leak would not carry as much meningitis risk as a larger one. Does this approach sound reasonable?
