Imaging of skull base cerebrospinal fluid leaks in adults.

Author information

Cerebrospinal fluid (CSF) leak occurs when there is an osseous and dural defect at the skull base, with direct communication of the subarachnoid space to the extracranial space, usually a paranasal sinus. Recognition of the leak site and source and appropriate treatment are necessary to avoid rhinorrhea or otorrhea, low-pressure headaches, and meningitis, known complications of CSF leak. The imaging evaluation has evolved over the past several decades. Description of current techniques available to direct treatment options, including multidetector thin-section computed tomography, and imaging recommendations are presented.
