(the brain CT SCAN without contrast, day 7). A-D The most of the post-operation changes including intraventricular and intraparenchymal air as well as parenchymal edema mainly disappeared at this time suggestive of improvement of post-operation changes (only minimal intraparenchymal, intraventricular and extra-axial air bubble is seen). A hyperdense rim seen around the left frontal lobe is suggestive of the remnant of post-operative subdural hematoma. Although some degree of intraventricular hemorrhage still could be seen, but no hydrocephalus is found suggestive of the well-functioning EVD. A remnant of hemorrhagic lesion of high convexity of the right frontoparietal junction is seen. Mentioned hypodense lesions within the cerebellar hemispheres and both cerebral hemispheres are faint in this study which can be due to some degree of improvement
