Abstract:
Spontaneous cerebrospinal fluid rhinorrhoea is a rare clinical entity. The accurate localisation of the leakage site is essential for surgical planning. Imaging techniques such as high-resolution computed tomography (CT), CT cisternography and magnetic resonance cisternography in variable combinations are performed for this purpose. This pictorial essay aims to present the spectrum of imaging findings in cases of spontaneous cerebrospinal fluid rhinorrhoea, which may be useful for radiologists in the determination of the site of cerebrospinal fluid leakage.
