Amarillis, Just to clarify — I hear about patients suffering from “presumed” leaks all the time, but never a “diagnosis” of a leak without any confirmation on imaging. Does that sound like it is splitting hairs? 🙂 It may be important because if it can’t be confirmed with imaging, we need to figure out if it is occult (perhaps leaking from the tail bone and can’t be seen on imaging), intermittent (perhaps only occurring with Valsalva, for example), or is it secondary to HIGH intracranial pressure? High intracranial pressure (especially when combined with weak connective tissue) can cause a leak, but if the underlying cause of HIGH ICP is not treated properly, the leak will return after repair. Ugh. What a journey, right?
