Cerebellopontine Angle Schwannoma and Meningioma in Contiguity: Surgical Implications in Neurofibromatosis

Concurrent occurrence of brain tumors in the same location is very unusual and has been noted in patients with neurofibromatosis. Two lesions, occurring in close contact but of different histology, are called contiguous tumors. Schwannoma and meningioma are the two common histologies reported to present as contiguous tumor.
