ABSTRACT

Background: Etiology of nasal cerebrospinal fluid leaks is due to trauma in 80%, iatrogenic in 16%, while spontaneous corresponds to 4%, of these, only 35% are located in the lateral recess of the sphenoid and represents approximately 1.4% of the total of nasal cerebrospinal fluid leaks. The Sternberg’s canal represents a very small amount of leaks of the lateral recess of the sphenoid, it can be demonstrated by persistence of the canal in imaging studies and sometimes by encephalocele.
Clinical case: A 47-year-old female patient with a spontaneous nasal cerebrospinal fluid leakes and sphenoid encephalocele, secondary to persistence of the Sternberg’s canal successfully treated endoscopically through one nostril.
Conclusions: Nowadays, transnasal endoscopic surgery is the approach of choice for the management of nasal cerebrospinal fluid leaks associated or not with encephalocele, it has an overall success rate of 90% and low morbidity and mortality rates. However, due to its anatomical location, the Sternberg’s canal is usually very difficult to access, which determines why in most of the few cases reported, there is an important recur- rence rate and often more than two endoscopic surgeries are necessary, including the need for a transcranial approach or ventriculoperitoneal shunt.
