Abstract
Skull base cerebrospinal fluid (CSF) leaks can be challenging to diagnose. We describe a first technical report on a fluoroscopy-guided multiphase flat panel computed tomography cisternography to diagnose a CSF leak in a complex postoperative anterior cranial fossa. The entry point, pathway of leakage, and exit point were visualized in detail. The feasibility and technical details are described. This technique could be an additional asset in the diagnostic work up of complex CSF leaks, not only of the anterior cranial fossa, but also complex CSF leaks of the middle cranial fossa.
