title: Nontraumatic subdural hematoma in a patient with osteogenesis imperfecta and renal failure.
abstract: Intracranial hematomas in patients with osteogenesis imperfecta rarely are reported despite an increased incidence of skull fractures. We present a case of a patient with osteogenesis imperfecta but without any history of trauma or chronic anticoagulation in whom a subdural hematoma occurred during hemodialysis. Despite operative intervention, the patient died. We could find no other cases in the medical literature of a patient with osteogenesis imperfecta who had an intracranial hematoma in the absence of a skull fracture. Patients with osteogenesis imperfecta may be at high risk for intracranial bleeding from coagulation abnormalities or otherwise trivial injuries.
