CSF rhinorrhea: non-contrast CT, contrast-enhanced CT cisternography or combined?

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