Parafalcine refers to a location near the falx cerebri, a sickle-shaped fold of dura mater that separates the two cerebral hemispheres in the brain. In medical imaging, such as MRI or CT scans, "parafalcine" lesions or masses indicate their proximity to this structure, which can be significant for diagnosing various conditions, including tumors or hemorrhages. Parafalcine regions are often involved in neurosurgical considerations due to their anatomical relationships with critical brain structures.
