Abstract
MR imaging has proved invaluable in anatomic depiction of the cerebrospinal fluid (CSF) spaces and the surrounding neural and non-neural tissue, although there are still some clinical situations (i.e., cases of CSF-flow alterations, communicating or non-communicating cyst masses bordering CSF pathways, or craniospinal CSF leaks) in which further imaging tests may be required for a definitive diagnosis.
This paper will review the state-of-the-art imaging in these processes, including Radionuclide Cisternography, plain Computed Tomography (CT) and enhanced-CT Cisternography/ myelography, as well as Magnetic Resonance Imaging (MRI) and contrast-enhanced Cisternography/myelography, emphasizing the latest CT and MR imaging refinement advances and proposing tailored specific approaches for two well-established clinical syndromes, namely CSF rhinorrhea and intracranial hypotension syndrome.
