Figure 1: — (a and b): a postoperative CT scan shows an abnormal subarachnoid contrast enhancement zone and a focal left parasagittal frontal hyperdense area. (c) A CT scan performed at 20 h shows a resorption of the subarachnoid hyperdensity and a new left parasagittal frontal hypodense area. (d) An MRI performed at 6 days reveals a hyperintense signal on FLAIR sequences in the left cortical precentral gyrus (as in case of vasogenic edema), excluding any signs of new ischemia.
