Abstract Magnetic Resonance Imaging has rapidly achieved a capability for evaluation the normal and pathologic states of the brain stem which not only rivals that of computed tomography, but may even surpass its the ability to perform direct multiplanar imaging without ionizing radiation and the lack of beam hardening artifacts are a distinctive features of MRI. The present study was carried out to compare between CT and MR in the diagnosis of brain stem lesions. The study included 23 patients presenting with signs and symptoms of brain stem lesions they were subjected to CT and MRI, they were 15 males and 8 females, their ages ranged from 5 to 65 years with a mean age of 38.6 years. They were 8 cases of brain stem gliomas (34.7%), 7 cases of white matter diseases (30.4%), 4 cases with brain stem in~arctiDns (17.3%), subacute haematoma with underlying vascular malformation was seen in one case (4%), brain stem tuberculoma was seen in one case (4%), multiple metastases were seen in one case (4%) the last case (4%) was a clival meningioma invading the brain stem. |
