Abstract:
ObjectiveTo study CT features of acute intracranial trauma and changes of hematoma in acute stage. MethodsCT findings of acute intracranial trauma of 152 cases were analyzed. ResultsIn 100 cases with intracranial hematoma, the hematoma enlarged obviously within 5-72 h after trauma in 25 cases; the hematoma enlarged markedly within 72 h-7d after trauma in 3 cases. In 76 cases of cerebral contusion, counter point trauma was found in 17 cases. In 61 cases of subarachnoid hemorrhage, high density in cerebral sulcus was shown in 49 cases. Skull fracture was found in 75 cases. Conclusions Intracranial hematoma may enlarge gradually within 7d after trauma. Cerebral contusion was partially due to counter point trauma. Hemorrhage in cerebral sulcus was demonstrated on CT as increased density in the cerebral sulcus, which is the most important sign of subarachnoid hemorrhage. Hemorrhage in interhemispheric fissure was demonstrated on CT as centipede-line increased density, which is an important sign for differentiating from subdural hematoma. Skull fracture was closely related with lntracranial trauma, which was complicated with adjacent extradural hematoma frequently.
