<CAPTION_DETAILS>The image is a CT scan of the brain, showing the cerebral structures without the use of contrast media. The region of interest, located centrally and in the lower-middle area of the brain, occupies approximately 0.5% of the image area and exhibits unusual features indicative of a CT scan, such as differences in density compared to the surrounding brain tissue. This region's relative position to other cerebral structures suggests it could be related to the surrounding brain tissue either by being a consequence of a localized injury or pathology, or potentially affecting adjacent areas due to mass effect or pressure changes within the brain.
