<REGION_LOC_DESCRIPTION>The image is a non-contrast computed tomography (CT) scan of the brain, showing the cerebral hemispheres, ventricles, and subarachnoid spaces without any medical devices visible. The region of interest, located centrally and in the lower-middle area of the brain, occupies approximately 1.6% of the image area and exhibits an unusual appearance indicative of a disease, characterized by a difference in density compared to the surrounding brain tissue. This region's relative position to other brain structures suggests it could be related to the surrounding tissue either as a cause of a disease or as an area jointly affected by a disease, potentially due to its proximity to vital brain structures.
