Accuracy of CT Cisternography in the Diagnosis of Cerebrospinal Fluid (CSF) Rhinorrhea
Background: Cerebrospinal fluid (CSF) Rhinorrhea refers
to the leakage of CSF into the nasal cavity. Accurate detection
and precise localization of the leak are essential for effective
management and prevention of serious complications such
as meningitis and brain abscess. Small or pinhole defects
pose a particular diagnostic challenge.
Methods: This retrospective cross-sectional study was
conducted from February 2016 to January 2024 and included
80 patients with clinical suspicion of CSF Rhinorrhea who
underwent CT cisternography at a tertiary care hospital.
High-resolution paranasal sinus CT scans were performed
following intrathecal administration of iodinated contrast
material. Demographic characteristics, CSF leak type, and
anatomical location were analyzed using descriptive statistics.
A CSF leak was considered present when direct contrast
extravasation or opacification of nasal packs was
demonstrated on imaging.
