All of the following statements about CSF leak are true, except:
Correct Answer: MRI (Gadolinium chanced) Tl images are best for diagnosis of site of leak
Description: High Resolution Fine Cut CT Scan (HRCT) is the best investigation of choice to identify the most likely site of Cerebrospinal fluid l(CSF) leak. A high resolution T2 - weighted MRI (Not Tl-weighted) may allow visualization of fluid within the sinuses but will allow identification of the site of leak only if the patient is leaking actively at the time of MRI. Thus MRI is not the best investigation.
