Abstract

This case report describes the symptoms and clinical course of a 35-year-old female patient who was diagnosed with a temporo-sphenoidal encephalocele. It is characterized by herniation of cerebral tissue of the temporal lobe through a defect of the skull base localized in the middle fossa. At the time of first presentation the patient complained about recurrent nasal discharge of clear fluid which had begun some weeks earlier. She also reported that three months earlier she had for the first time suffered from a generalized seizure. In a first therapeutic attempt an endoscopic endonasal approach to the sphenoid sinus was performed. An attempt to randomly seal the suspicious area failed. After frontotemporal craniotomy, it was possible to localize the encephalocele and the underlying bone defect. The herniated brain tissue was resected and the dural defect was closed with fascia of the temporalis muscle. In summary, the combination of recurrent rhinorrhea and a first-time seizure should alert specialists of otolaryngology, neurology and neurosurgery of a temporo-sphenoidal encephalocele as a possible cause. Treatment is likely to require a neurosurgical approach.
