Dural sinus thrombosis after minor head injury in a child

Introduction: Dural sinus thrombosis following minor head injury is rare. We report such a case in a child after mild head injury. Clinical Picture: A 4-year-old child presented with giddiness and vomiting after a fall. Clinical examination was unremarkable. Magnetic resonance venogram revealed thrombosis of the right sigmoid and transverse sinuses. Treatment: The patient was managed conservatively. Outcome: Repeat scans 10 weeks after injury showed recanalisation of the thrombosis. Conclusion: Dural sinus thrombosis should be excluded in children presenting with persistent giddiness and vomiting after minor head injury. Ann Acad Med Singapore 2005;34:639-41
