(A, B) T2-weighted axial and sagittal images reveal focal hyperintensity within the dorsal medulla oblongata. (C) Fluid-attenuated inversion recovery coronal MRI shows hyperintense white matter lesions predominantly involving medulla oblongata. (D) Lesions of medulla oblongata were basically normal after therapy (white arrow).
Brain Aneurysm Imaging: magnetic resonance image (MRI) of a middle-aged woman with progressive headaches, aphasia, and right-sided hemiparesis. A large intracerebral mass with a significant amount of surrounding edema is depicted. The lesion i
Dyke-Davidoff-Masson syndrome (DDMS) was initially described as changes in the skull seen on skull x-ray in patients with cerebral hemiatrophy but is now applied more broadly to cross-sectional imaging also.
