[Liquorrhoea and acute meningitis. Complications of a cerebrospinal fluid fistula secondary to a skull fracture suffered 45 years previously].

A case is described in which liquorrhoea and meningitis occur as complications of cerebrospinal fluid fistula. The patient incurred the initial skull fracture 45 1/2 years prior to that. Three hypotheses as to the long interval are discussed. The authors propose to look for a cerebrospinal fluid fistula after every important trauma of the skull.
