Each of two or more children or offspring having one or both parents in common; a brother or sister. ---- Hinojosa et al. reported the case of two [[sibling]]s in whom a [[diagnosis]] of [[hemophilia]] coexisted with the presumption of a non-accidental head trauma. [[Child abuse]]s were inflicted in both [[child]]ren with a spare time of 2 years. A diagnosis of mild hemophilia was prompted in the first sibling after initial NAHT, while inflicted trauma was evident in the second sibling after [[neuroimaging]] findings and concomitant lesions. Lessons from this case in co-existing bleeding disorders and inflicted trauma and legal implications derived will be discussed thereafter.The possibility of a bleeding disorder should be considered in all children presenting with unexplained bleeding at a critical site in the setting of suspected physical maltreatment, particularly [[intracranial hemorrhage]] (ICH) ((Hinojosa J, Simó M, Armero G, Becerra MV, Alamar M, Candela S, Culebras D, Muchart J, Berrueco R.
