Introduction: Tumors of the cerebellopontine (CP) angle account for 5%-10% of all intracranial tumors. Schwannomas are the most common tumor with usual presentation as hearing loss and non-acoustic tumors usually presented with variety of symptoms and sign from headache to cranial nerve deficit to cerebellar features to brainstem compression features. Aim: Evaluation of the incidence of various CP angletumors in western Rajasthan and comparison of histopathology with surgical outcome and complications. Methods: A prospective study was conducted in Neurosurgery department of Dr. S. N. Medical College, Jodhpur, Rajasthan for 2 years duration from September 2019 to August 2021. Total 30 patients were evaluated during this period. Evaluation was done on demography, histopathology, clinical and radiological aspects and post-operative outcomes. Simple statistical methods like table and graphs were used. Results: Tumors of the CP angle account for 5%-10% of all intracranial tumors. Most common extra-axialCP angle tumor is Schwannoma (46%), followed by Meningioma (23%), Epidermoid (20%), Arachnoid cysts (15%).41-50 years is the most common age group involved. Schwannomas are common extra-axial CPA followed by meningiomas and others. Overall, most common presenting symptom was hearing loss, followed by headache, tinnitus and others. Complication was seen in 10cases in the form of cranial nerve deficit, hydrocephalous, cerebellar symptoms, hematoma and wound infection. Conclusion: Schwannomas are the most common tumor with usual presentation as hearing loss and non-acoustic tumors usually presented with variety of symptoms and sign from headache to cranial nerve deficit to cerebellar features to brainstem compression features.
