CT Examination: Techniques for Evaluation of the Cerebello-Pontine Angle, If a mass is encountered, CT studies should also display the relationship of the tumor to such important eurovascular structures as the anterior and posterior inferior cerebellar arteries, the facial nerve and the vestibulocochlear (statoacoustic) nerve. Proper demonstration of these structures imp

Pathology of the Cerebello-Pontine Angle,. These structures include the cranial nerves, vessels, arachnoid mater, dura mater and bone. The most common primary cerebello-potine angle tumor is the acoustic neurinoma. The second most common is meningioma. All other primary tumors such as epidermoids, neurinomas of other cranial nerves, aracho

Meningioma of the Posterior Surface of the Petrous Bone,he cerebellopontine angle constitute 5 to 8.4% of all meningiomas and 1 to 1.7% of all intracranial tumors (78, 365, 416, 418). Indeed, most infratentorial meningiomas (42 to 56.6%) originate from the posterior surface of the petrous bone and primarily involve the pontocerebellar cistern (57, 630).

Epidermoid Tumors,rial tumors (166). The most frequent site of posterior fossa epidermoids is the cerebello-pontine angle. Epidermoids are the third most common tumor of the cerebello-pontine angle with a frequency of 2.8 to 6.3% of all cerebello-pontine angle masses (218, 473, 629, 640).

Arachnoid Cysts of the Cerebello-Pontine Angle,erior fossa was given by Mannsell in 1889 (339). The true etiology remains obscure. Congenital (28), inflammatory (6) and traumatic factors (557) have been postulated. Histologic (538) and electron-microscopic studies (469) show that arachnoid cysts are intraarachnoid lesions originating from clefti
