Congenital intra-extracranial dumbbell schwannoma of temporal fossa unassociated with any major cranial nerve.
Intracranial schwannomas commonly arise from the vestibular nerve and less commonly from other cranial nerves. On rare occasions, they may be intraparenchymatous, intraventricularor intrasellar. However, the occurrence of a congenital solitary intracranial extradural schwannoma unrelated to any cranial nerve in the absence of von Recklinghausan's syndrome is exceptional. The authors report a unique, heretofore unreported case of a congenital temporal extradural schwannoma, unassociated with any known cranial nerve and with a transcranial extension presenting as a temporal fossa mass since birth in a 16-year-old female patient. Total resection of this tumour was uncomplicated. A brief review of the relevant literature is presented.
