[Massive traumatic hematoma localized in the basal ganglia: treatment by CT-guided stereotactic aspiration surgery].

A case of massive traumatic hematoma of the basal ganglia which was treated successfully by CT-guided stereotactic aspiration surgery, was reported. A 6-year-old boy was admitted 2 hours after a traffic accident. He had no neurological focal signs except for disturbance of consciousness on admission. CT scan revealed a massive hematoma in the right basal ganglia. His neurological status gradually deteriorated 6 hours after the trauma and the size of the hematoma increased on serial CT scan. Then, CT-guided stereotactic aspiration surgery was performed and about 15.5 ml of hematoma clot was successfully evacuated. He made an uneventful recovery from the operation and gradually improved. The final outcome was that he showed moderate disability at 3 months after the trauma. The possible mechanism of development of hematoma in this lesion, and indication of CT-guided stereotactic aspiration surgery were also discussed.
