Classification of craniocerebral Frauma in CT Imaging

Objective:To improve the abilty of recognizing various craniocerebral trauma. Materials and Methods:135 craniocerebral trauma csases were cases were collected,in which 98 cases were male and 37 cases were female.Their ages were from 4 to 77,with 24.83 on average.In this group,93 cases were traffic accidental trauma,28 cases were injury from fall,14 cases were stricken trauma.101 cases had coma.All cases were perfomed craniocerebral axial CT scan. In terms of various craniocerebral trauma combined with each other,their CT findings were analysed in details.Results:Among the 135 craniocerbral trauma cases,133 were compound craniocerebral trauma, 2 cases were simple contusion and laceration of the brain 104 cases had epiduralhaematoma,75 of which were accompanied with cranial fracture in the same location (72.15%),and 27 of which with contusion and laceration of the brain, among the 27 patients with contusion and laceration of the brain,19 cases were in a contrecoup position (70.37%);20 cases had subdural haematoma ,15 of which were in contrecoup position (75%),12 of which were accompanied with contusion and laceration of the brain,the latter being in the vicinity of the subdural hematoma;47 cases had CT scans with in 2 hours and CT reexamine in 4 hours to 5 days after trauma,38 of which were found that their traumatic changes had progressed (80。95%)。Conclusions:Epidural haematoma usually accompanies cranial fracture in the same location; contusion and laceration of the brain in association with extradural haematoma usually situates in a contrecoup position; most subdural haematomas are also in the contrecoup site;traumatic craniocerebral changes may progress in a short time after the accident.
