Abstract
- Background: Radiologic diagnosis of CSF leaks is challenging. We evaluated the diagnostic value of non-contrast CT and contrast-enhanced CT cisternography in identifying the presence of CSF rhinorrhea and site of leak as well as comparing them to surgical data and/or clinical follow-up. Results: Fifty patients (20 males and 30 females) were included in our study with age ranging from 19 to 67 years. 76% of cases had spontaneous CSF rhinorrhea. Cribriform plate defect was the most common site of CSF leak, accounting for about 50% of cases. The highest sensitivity, specificity, PPV and NPV for diagnosis of CSF rhinorrhea were observed with the combined NCCT and CECTC with values 87%, 100%, 100% and 67%, respectively. Conclusion: Accurate surgical planning and successful dural repair requires accurate localization of the dural and osseous defects. CT cisternography which already involves pre-cisternography non-contrast images holds great sensitivity in detection of the exact defect site together with confirmation of the CSF leak.
