Evaluation of Stereotactic Radiosurgery for Cerebellopontine Angle (CPA) Meningioma and Shwannoma after Microsurgical Decompression
Background: CPA tumors are the most common neoplasms in the posterior fossa. After microsurgical decompression, the residual parts of meningiomas and shwannomas can be treated with stereotactic radiosurgery. Objective: The aim of the study is to evaluate long–term follow up of stereotactic radiosurgery after microsurgical decompression. Patients and Methods: Our study included a total of 32 pat...
متن کاملCerebellopontine angle meningioma presenting with hearing loss
We present the case of a 48-year-old woman with a cerebellopontine angle meningioma who presented with sensorineural hearing loss. The lesion was nearly 4 cm in maximum dimension and extended into the internal auditory canal. Hearing loss resulting from cerebellopontine angle tumor is most commonly caused by vestibular schwannomas, which arise directly from the sheath of the vestibular nerve (V...
متن کاملParoxysmal tinnitus due to a meningioma in the cerebellopontine angle.
A 44 year old woman presented with frequent paroxysms of unilateral tinnitus and ataxia which were abolished by treatment with carbamazepine. Hearing was normal and initially there were no other symptoms or signs between paroxysms. Brain stem evoked responses from the affected left ear were absent and MRI showed a large tumour in the left cerebellopontine angle. This was completely removed and ...
متن کاملCerebellopontine angle meningioma resulting in middle-ear polyp.
Extracranial spread of meningiomas to involve the middle ear is very rare. We present the case of a 43-year-old woman with a known cerebellopontine angle meningioma who subsequently presented with left-sided otalgia and a middle-ear mass extruding through the tympanic membrane due to local invasion of the meningioma. The tumour was excised surgically. A discussion of the relevant literature is ...
متن کاملHearing improvement after resection of cerebellopontine angle meningioma: case study of the preoperative role of transient evoked otoacoustic emissions.
In a retrospective case study of a patient with a right-sided cerebellopontine angle mass lesion, transient evoked otoacoustic emissions were robustly present despite a severe to profound sensorineural hearing loss and abnormal auditory brainstem response. These results were interpreted as suggestive of a neural site of lesion, and the potential for planned, preserved, or improved hearing by a ...
