Abstract:
We studied two patients with spontaneous cerebrospinal fluid (CSF) rhinorrhoea with MRI and other imaging modalities. T2-weighted images proved most useful for the detection and localisation of the CSF leakage. MRI appeared to provide an accurate and noninvasive method for preoperative investigation of spontaneous CSF rhinorrhoea.
