  A contusion is tissue injury resulting from external forces, like a direct blow or shock wave, without breaking the overlying tissue (e.g., cornea or sclera). These injuries often occur at points where brain tissue contacts bony protrusions on the skull's base, mainly the inferior parts of the frontal and temporal lobes. Contusions harm small blood vessels and brain tissue, leading to hemorrhages perpendicular to the cortex. They are typically most severe at the tops of cerebral gyri but can extend into subcortical white matter, forming wedge-shaped hemorrhagic areas. "Coup" contusions develop under the impact site, "contrecoup" contusions opposite it, and herniation contusions at brain herniation margins due to raised intracranial pressure. Lacerations involve physical brain parenchyma disruption and may accompany surface contusions. Contusion symptoms encompass pain, swelling, bruising, and limited movement. Prolonged swelling suggests intramuscular contus...
