Intracranial hemorrhage secondary to head trauma is a major cause of morbidity and mortality in patients with bleeding disorders. Indications for head computerized tomographic scanning (CT scan) on patients with bleeding disorders who sustain head trauma are not well established. We retrospectively reviewed the medical records and head CT scan results of 21 patients with bleeding disorders. Five patients had more than one episode of head trauma. The severity of head trauma per episode was classified according to objective clinical findings as minor in 12 episodes, moderate in 12, and severe in four. In three of four patients with severe head trauma, the CT scan showed evidence of intracranial hemorrhage. In this series, all 17 patients with 24 episodes of moderate or minor head trauma had normal head CT scans. We conclude that a larger prospective study is needed to further evaluate the diagnostic value of head CT scan in hemophilia patients with minor or moderate head trauma, as defined in this study.
