“…15) The source of bleeding in boxers with ASDH was also either a bridging or a cortical vein. 26 , 27) Laceration of large bridging or cortical veins may exacerbate cerebral perfusion by venous congestion or infarction, resulting in brain swelling. 37) Hits directed eccentrically to the head of boxers produce rotational acceleration.…”

We review the current topic in sports-related head injuries including acute subdural hematoma (ASDH), concussion, and chronic traumatic encephalopathy (CTE). Sports-related ASDH is a leading cause of death and severe morbidity in popular contact sports like American football in the USA and judo in Japan. It is thought that rotational acceleration is most likely to produce not only cerebral concussion but also ASDH due to the rupture of a parasagittal bridging vein, depending on the severity of the rotational acceleration injury. Repeated sports head injuries increase the risk for future concussion, cerebral swelling, ASDH or CTE. To avoid fatal consequences or CTE resulting from repeated concussions, an understanding of the criteria for a safe post-concussion return to play (RTP) is essential. Once diagnosed with a concussion, the athlete must not be allowed to RTP the same day and should not resume play before the concussion symptoms have completely resolved. If brain damage has been confirmed or a subdural hematoma is present, the athlete should not be allowed to participate in any contact sports. As much remains unknown regarding the pathogenesis and pathophysiology of sportsrelated concussion, ASDH, and CTE, basic and clinical studies are necessary to elucidate the crucial issues in sports-related head injuries.

“…In boxing, acute TBI can be caused by a minimal (no loss of consciousness, Glasgow Coma Scale (GCS) of 15), mild (history of loss of consciousness, GCS [14][15] or moderate/severe TBI (associated with e.g. subdural haematoma and intra-cerebral haemorrhage) [1][2][3][4]. TBI may be associated with knock-out (KO) with loss of consciousness, but may also be caused by the cumulative effect of sub-concussive translational and rotational punches to the head [5].…”

“…In this case, the patient's papilledema was likely caused by boxing trauma leading to a chronic SDH and persistent increased intracranial pressure. Kushi et al (5) showed that SDH from boxing injuries are more likely to occur in younger patients, have longer lucid intervals, lack skull fractures or cerebral contusions, and involve trauma to the bridging and cortical veins; however, all patients in this study had acute SDH and initially presented with altered consciousness or headache.…”
