Post-traumatic subdural hygromas, or hydromas, are collections of fluid most often caused by severe head injuries. They present from the onset as hypodense pictures on computerized axial tomography scan (CAT-scan). CAT-scan is the best way to diagnose and to follow the evolution of hygromas. Out of 3002 patients admitted for head injuries, the authors have collected 70 cases of hygromas. 24 of these 70 patients underwent burrhole evacuation of the hygroma. The other 46 had conservative treatment. In both groups, the clinical picture, at short or long-term follow up, was more influenced by the associated brain injuries (extra- or subdural hematomas, cerebral contusion) than by the evolution of the hygroma itself. The surgical treatment of the hygroma was seldom followed by a significant improvement in the patients' condition. As the size of hygromas usually diminishes spontaneously, it seems appropriate most of the time to treat them conservatively and to follow them by CAT-scan, according to the clinical picture.
创伤后硬膜下积液，或称为水瘤，是最常由严重头部损伤引起的液体聚集。在计算机断层扫描（CAT扫描）上，它们从一开始就表现为低密度影像。CAT扫描是诊断和跟踪积液演变的最佳方法。在3002例因头部损伤入院的患者中，作者收集到70例积液病例。这70例患者中有24例接受了钻孔引流积液治疗。另外46例接受了保守治疗。在两组中，短期或长期随访时的临床表现，受相关脑损伤（硬膜外或硬膜下血肿、脑挫伤）的影响比受积液本身演变的影响更大。积液的手术治疗很少能使患者病情得到显著改善。由于积液大小通常会自发减小，所以大多数情况下，根据临床表现对其进行保守治疗并通过CAT扫描进行跟踪似乎是合适的。
