Case contributed by A.Prof Frank Gaillard


Left hemiplegia.

Patient Data

Age: Elderly

CT brain on admission

Selected axial images from a CT of the brain demonstrate that the right middle cerebral artery is hyperdense and there is loss of normal grey-white matter differentiation in the MCA territory. 


CT brain 1 day later

CT one day later at same level shows the vessel being even more hyperdense, due to clot retraction and further low attenuation change in the surrounding brain.
