The tumor invades adjacent bony and soft tissue structures of the temporal bone (the mastoid, inner ear, and middle ear) and cerebellopontine angle
, including the cranial nerves .
Experience with cerebellopontine angle
Key Words: Cerebellopontine angle
tumor, Acoustic neuroma, Epidermoid, Arachnoid, Meningioma
Finally, brain MRI performed one year later demonstrated interval resection of the right cerebellopontine angle
tumor without evidence of residual tumor (Figure 3(d)).
The vestibulocochlear nerve, with an emphasis on the normal and disease internal auditory canal and cerebellopontine angle
We report a rare case of contralateral hearing loss after vestibular schwannoma excision in a 48-year-old man who underwent surgery via a suboccipital approach for removal of a nearly 2-cm lesion involving the right cerebellopontine angle
CSF seeding of the tumour was detected along the ventral surface of the brainstem and on the cerebellopontine angle
cisterns, the anterolateral temporal lobes and posterior fossa, the leptomeninges and the cauda equina of the spine (Fig.
It accounts for 8 10% of all primary intracranial tumours and 80% of Cerebellopontine angle
Functional surgery of cerebellopontine angle
by minimally invasive retrosigmoid approach.
Schwannoma and meningioma association of cerebellopontine angle
Cerebrospinal fluid (CSF) rhinorrhea is a common complication after skull base surgery for cerebellopontine angle
Cerebellar liponeurocytoma most commonly involves the cerebellar hemispheres but may be located in the paramedian region or vermis and may extend to the cerebellopontine angle
or fourth ventricle.
3 There is no sex predilection but cerebellopontine angle
lipomas appear twice as common in males.
The remaining material is organized by anatomy, with seven chapters focusing on the external auditory canal and pinna; the middle ear and mastoid; temporal bone vascular anatomy, anomalies, and disease, with an emphasis on pulsatile tinnitus; the inner ear and otodystrophics; temporal bone trauma; anatomy and development of the facial nerve; and the vestibulocochlear nerve, with an emphasis on the normal and diseased internal auditory canal and cerebellopontine angle
8 cm in diameter) located in the right cerebellopontine angle
and cerebellum (Figure 2, panels A and B).
