The force sustained from a boxing blow can be as powerful as being hit with a 6-kg wooden mallet striking at 20 mph. Bilateral cerebellar hemorrhage secondary to trauma is a rare entity that has not been reported in the literature previously. One can only speculate as to how a boxer could potentially develop a cerebellar bleed. Regardless of whether a very powerful punch or the act of falling back and hitting the occipital region directly on the floor, it is very likely that a predisposing factor exist. We present you a rare case of a 26 year-old male boxer who was knocked out in a boxing match and was noted to have acute parenchymal and subarachnoid hemorrhage bilaterally in the cerebellar hemispheres. Our report highlights the need to consider cerebellar bleed in boxers who present after ataxia after boxing/knocked out. http://pubs.sciepub.com/ajmcr/7/10/4/ajmcr-7-10-4.pdf bilateral cerebellar hemorrhage boxing
