Aclient has undergone nasal hypophysectomy surgery. during post-operative care, which finding indicates cerebrospinal leakage?

A yellow edge around the nasal discharge of a client is a clear evidence cerebrospinal leakage. This leakage is caused by a defect that is forming in the outer covers of the brain. This condition should be taken care of immediately to avoid meningitis and other worst cases. 

That would be a working theory.
