title: Traumatic basal ganglia hematomas: an analysis of 20 cases.
abstract: Twenty patients with traumatic basal ganglia hematoma (TBGH) were studied. Of the 20 patients, 16 were male and 4 were female, with an age range of 4-89 years (mean, 54.4 years). The causes of injury were traffic accidents in 12 patients and falls in 8. The mean admission GCS score was 7.5. Skull fractures were revealed in five patients (25 %). The hematoma was found in the putamen in 15 patients (80 %), the thalamus in 4, and the caudate in 1. The mean hematoma volume was 10.7 mL. The CT findings indicated focal contusions in 9 patients, subdural hematoma in 5, intraventricular hemorrhage in 4, subarachnoid hemorrhage in 10, and diffuse axonal injury in 5. Six patients (30 %) underwent surgery. The final outcomes were poor: 7 patients (35 %) died, 1 was in a vegetative state, 4 experienced severe disabilities, and 8 patients (40 %) made a favorable recovery. The statistical analysis identified the GCS score and midline shift as prognostic factors.Our study revealed interesting characteristics of TBGH, including a high frequency of putaminal involvement, a low frequency of skull fractures, a high frequency of associated intracranial lesions, and a high poor outcome and mortality rate.
