RESUMO
UNLABELLED: The aim of this study is to access magnetic resonance as the imaging modality of choice in differentiation of cerebellopontine angle tumors. MATERIAL AND METHODS: In period of five years in 53 patients were diagnosed CPA tumors. 31 were women, 22 men, range age 14 to 72 years. All patients were examined on 1.0 Tesla magnetic resonance unit, using T1, PD, T2 WI sequences, and after paramagnetic contrast administration T1 W1 in three ortogonal planes. REZULTS: In 44 (83%) patients were diagnosed acoustic schwannoma (NVIII), and 8 patients of these had Neurifibromatosis Type 2. In 2 (4%) patients were diagnosed trigeminal schwannoma (NV), in 2 (4%) hypogossal schwannoma. By 5 (9%) patients were diagnosed meningiomas. All diagnoses were by histology confirm. CONCLUSION: Thanks to its multiplanar and multi-parameters capabilities Magnetic resonance allowed precise location and characterization of CPA tumors. MR is the imaging modality of choice for preoperative work-up of cerebellopontine angle tumors.
