Ischemic stroke
It is clear from the above CT scans that the scan in the question is “ischemic stroke”. However, it is interesting to note that this patient has sudden loss of consciousness for 10 minutes with such a massive stroke which is practically unsual to find with a short period of time. Therefore always ask about onset of symptoms to your patients. Remember large ischemic strokes are commonly caused due to middle cerebral artery occlusion or internal carotid artery occlusion.
