Background; Cerebello pontine angel masses are the most common neoplasm in posterior fossa accounting for 5-10 % of intracranial tumors. Aim; to evaluate the lesions that arise from this angle by using MRI sequences as T1 (with out and with contrast), T2, FLAIR, Diffusion Weighted and spectroscopy. Methods; This study included 25 patients age ranged  25 -55 years, and were subjected to full history talking, Clinical examination, laboratory investigations and MRI for patient with suspected cerebello pontine angle lesions. Results; Females are frequently involved by these lesions (19 patients) while males are less (6 patient). Among our patients , the most common presenting symptoms were hearing loss  in 17 patients (68.0%) headache in 10 patients ( 40.0%), tinnitus in 9 patient ( 36.0 %)  neuralgia  in 5 patients ( 20.0 %), vertigo in 2 patients (8.0%), hemi facial spasm in one patient (4.0%) and wasting of mastication muscles (4.0%). Out of the studied patients , final diagnosis by MRI  revealed acoustic schwannoma in 12 patients ( 48.0%) which was the most common pathology ,followed meningioma  that were noted in 7 patients  (28.0%),  epidermoid cyst in one patient (4.0%),prominent AICA  in one patient (4.0 %), paraganglioma in one patient (4.0%),cystic neurofibroma in one patient (4.0%), neurofibromatosis type 2 in one patient (4.0%) and arachnoid cyst  in one patient (4.0 %). Conclusion: MRI is the gold standard method to differentiate the lesions by anatomical site of origin, shape, signal intensity and behavior after contrast media injection.
