Abstract: The co-existence or concurrent occurrence of brain tumours having different histomorphological features, in the absence of neurofibromatosis central (NF2) or history of irradiation is very rare. Such co-existence of brain tumours with different histology are referred to as collision tumours, concomitant tumours or contiguous tumours. The patient had no history of Von Recklinghausen’s disease nor had any personal or family history of phacomatoses, but, however, he had history of undergoing near total resection of left-sided vestibular schwannoma one year backThe simultaneous occurrence of meningioma and schwannoma is highly uncommon in cerebellopontine angle with only few published cases of co-existing meningioma and schwannoma in patients with no history of neurofibromatosis or other such phacomatoses, albeit this phenomeno of co-existence of these tumours is associated with neurofibromatosis 2 or other phacomatoses. It is also proposed that reactive meningothelial hyperplasia adjacent to the main tumour could be responsible for the presence of meningothelial component within schwannoma
