ABSTRACT
The present study describes the cranial computed tomography (CT) scan findings of 2,000 cases of mild head trauma (HT) in Curitiba, Southern Brazil. The mean age of the entire series was 30.8 FACE="Symbol">±19 years. The overall male to female ratio was 21. The most common causes of head injury were interpersonal aggression (17.9 percent), falls (17.4 percent), automobile accidents (16.2 percent), falls to the ground (13.1 percent) and pedestrian injuries (13 percent). Alcohol intoxication was associated with HT in 158 cases (7.9 percent). A normal CT scan was seen in 60.75 percent (1215) and an abnormal CT scan in 39.25 percent (785) of patients. Out of 785 abnormal CT scan, 518(65.9 percent) lesions were related to HT. The most common CT scan HT related findings were soft tissue swelling (8.9 percent), skull fractures (4.3 percent), intracranial and subgaleal hematomas (3.4 percent and 2.4 percent), brain swelling (2 percent) and brain contusion (1.2 percent). Out of 785 abnormal CT scans, 267 (34.1 percent) lesions were not related to head trauma. Incidental CT scan findings included brain atrophy (5.9 percent), one calcification (5.2 percent) several calcifications (2.4 percent) (probably neurocysticercosis in most cases), ischemic infarct (1.9 percent) and leukoaraiosis (1.3 percent). These findings showed the importance of CT scan examination in mild head injuries. Further studies to identify mild HT patients at higher risk of significant brain injury are warranted in order to optimize its use
