<CAPTION_DETAILS>The image is a non-contrast computed tomography (CT) scan of the brain, showing the cerebral structures without the use of contrast media. The region of interest, located centrally and in the middle of the image, occupies approximately 2.8% of the area and appears to have a different density compared to the surrounding brain tissue, which may indicate an abnormality such as a hemorrhage. This abnormal area could be related to the surrounding brain tissue either by causing a mass effect or by being the result of a pathological process within the brain itself.
