Epidermoid Causing Ischemic Stroke in the Brainstem

Figure 1

(a) Axial image of plain computed tomography (CT) showing hypodense lesion in right cerebellopontine angle and prepontine cistern with compression of the brainstem. Axial T2 (b) and T1 (c) weighted MR images showing the lesion to be hypointense on T1 and hyperintense on T2 sequence (black arrows outline the tumour). (d) and (e) are T1 weighted axial and sagittal images. (f), (g), and (h) are axial T2, FLAIR, and diffusion weighted images, respectively, revealing another lesion of hyperintensity and restricted diffusion in right half of midbrain.
