INTRODUCTION:– Tumors of the CP angle account for 5% to 10% of all intracranial neoplasms. VSs are the most common CP angle

tumor then, followed by meningiomas and the epidermoids. Much rarer primary tumors are schwannomas of other cranial nerves: of the

trigeminal nerve, of the facial nerve, or of the caudal cranial nerves; paragangliomas, chordomas, chordosarcomas, arachnoid or

neurenteric cysts, dermoid tumors, and metastases. The CP angle could be secondarily involved by tumors extending from the ainstem

or fourth ventricle: gliomas, ependymomas, choroid plexus papillomas, medulloblastomas, or lymphomas.

Material And Methods:–Clinical data and histopathological evaluation of 55 patients were studied who presented with CP angle mass

and retrospectively reviewed.

RESULT:– In our study of 55 cases majority of them were benign with 51 cases and four cases were malignant. Most common cp angle

tumor diagnosed histopathologically in our set up was Vestibular Schwanomma. Age group varied from 1st decade to 7th decade.

Conclusions:– A large variety of unusual lesions can be encountered in the CPA and should be differentiated from acoustic neuromas or

meningiomas.Histopathology plays a key role in differentiating different CPA lesions and is primarily based on the site of origin of the

masses and their variable clinical presentation
