Spontaneous sphenoid sinus cerebrospinal fluid leak and meningoencephalocele – are they due to patent Sternberg's canal?
نویسندگان
چکیده
Sternberg's canal is a congenital bony defect in the lateral wall of the sphenoid sinus. If it persists to adulthood, it may become a source of spontaneous cerebrospinal fluid leak (CSF) and meningoencephalocele. The aim of the study was to describe the authors' experience and review articles related to spontaneous sphenoid sinus CSF leaks and Sternberg's canal. We analysed patients managed surgicallly due to sphenoid sinus CSF leak and performed a PubMed database search. Two female patients with spontaneous CSF leak of sphenoid origin were found. Both patients underwent surgery with the endoscopic endonasal approach, and the defect was closed using the multi-layer technique. Twelve articles related to CSF leaks of sphenoid origin (due to Sternberg's canal) were found in the PubMed database. Lines of lesser resistance within sphenoid bone may underlie CSF leak pathology together with intracranial hypertension. The endoscopic transnasal approach to the sphenoid sinus is an excellent alternative to standard transcranial procedures.

One type of congenital intrasphenoidal meningoencephalocele is remnant of lateral craniopharyngeal (Sternberg's) canal. We present a case of a 23-year girl with 10-month history of right side CSF rhinorrhea. CT scan, MRI revealed congenital meningoencephalocele and CSF leak from middle fossa to right side of sphenoid sinus, and there were bony defects at the floor of the anterio...

INTRODUCTION AND OBJECTIVES Cerebrospinal fluid leaks associated to meningoencephaloceles of the sphenoid lateral recess are rare entities. A congenital bony defect at this level results in the persistence of Sternberg's canal, or a lateral craniopharyngeal canal, which is supposed to be the origin of these lesions. Our objective was to show that the endoscopic transpterygoid approach is an eff...

BACKGROUND Intrasphenoidal encephaloceles are extremely rare findings. Sternberg's canal is a lateral craniopharyngeal canal resulting from incomplete fusion of the greater wings of the sphenoid bone with the basisphenoid. It acts as a weak spot of the skull base, which may lead to develop a temporal lobe encephalocele protruding into the lateral recess of the sphenoid sinus (SS). CASE DESCRI...

Endoscopic surgical techniques allow treating various pathological diseases of the cranial base, including cerebrospinal fluid leaks (CSF). These approaches have a high success rate and reduce surgical time and morbidity. However, when they are located in the lateral wall of the sphenoid, the surgery is more complex. In our case, the CSF appeared to be related with a Sternberg's canal. Predispo...
متن کاملVariations in Lateral Sphenoid Sinus Wall Defects
Defects in the lateral wall of the sphenoid sinus are a rare cause of cerebrospinal fluid (CSF) rhinorrhea. The etiology of these defects may be congenital or acquired. A dehiscent lateral craniopharyngeal canal, or Sternberg canal, arises from a malunion of two parts of the developing sphenoid bone: the greater wing and the basisphenoid.1,2 Originally reported in 4% of healthy adults,3 its tru...
