Spontaneous Recurrent CSF Rhinorrhoea: A Rare Case and Review of Literature.

Cerebrospinal fluid (CSF) rhinorrhoea is the leakage of CSF through the communication between the subarachnoid space and the nasal cavity. Surgical repair is indicated in all cases of spontaneous leaks, recurrent leaks, leaks that do not stop after conservative management and cases with history of meningitis. We present a rare case of spontaneous (delayed onset post traumatic) CSF rhinorrhoea with multiple defect sites, which was treated with an endonasal endoscopic repair. The patient was asymptomatic for 9 years after surgery, and then presented with a spontaneous left frontal recess CSF leak, which was closed using endonasal approach.
