[A case of traumatic hematoma in the basal ganglia: successful drainage with ultrasound-guided aspiration surgery via burr hole].

A case was reported of massive traumatic hematoma of the basal ganglia which was treated successfully by ultrasound-guided aspiration surgery. A 8-year-old girl was transferred to our hospital 20 minutes after a traffic accident. She was in stupor and had right hemiplegia. A skull x-rays showed right temporal linear fracture and a head CT disclosed left massive putaminal hematoma. Ultrasound-guided aspiration surgery via a burr hole was performed under general anesthesia and 30 ml of hematoma was successfully evacuated. Her symptoms and signs improved gradually and she was discharged on foot 3 weeks after the accident. The clinical feature and mechanism of development of the hematoma in this lesion, and usefulness of ultrasound-guided aspiration surgery were also discussed.
