肾上腺损伤的CT表现

目的探讨肾上腺损伤的CT表现，评价CT检查的诊断价值。方法收集8例经手术或CT复查随访证实的外伤车祸患者肾上腺损伤的CT资料和临床资料进行回顾性分析。结果外伤后急性期（1～7d）CT扫描，显示。肾上腺血肿8例，CT表现为肾上腺区圆形、类圆形高密度影；肾上腺周围组织损伤6例，其中4例。肾上腺周围脂肪内条纹状、斑片状高密度模糊出血影，3例膈肌增粗，密度增高，本组中8例在外伤后亚急性期（8d-1个月末）和慢性期（1个月后）CT复查，表现为肾上腺血肿密度从边缘开始缓慢降低，肾上腺形态逐渐恢复正常。结论CT检查反映了肾上腺损伤的病理解剖改变，是诊断肾上腺损伤的主要方法。

CT findings of adrenal injury

Objective To discuss the CT manifestations and CT diagnostic value of adrenal gland injury. Methods The CT data and clinical data of 8 cases adrenal injury verified by operation or following up were analyzed retrospectively. Results The manifestations of CT scanning in acute stage （one day to 7 days） after injury disclosed, there are 8 cases of adrenal hematomas, which exhibited round or roundish shadow, there were 6 cases of periadrenal tissue injury, 4 of which had stripe-like or plaque-like vague hemorrhagic shadows with high density in periadrenal fat and 3 of which showed vague margin of the crura of diaphragm or local increased density in the crura of diaphragm, 8 patients reexamined in subacute stage （8 days to one month） and chronic stage （after one month） ,after injury and it was found that the density of shadow reduced from margin of hematoma and that the shapes of adrenal gland recovered gradually. Conclusion CT scanning discloses the pathoanatomic changes of adrenal injury, and is the main way to diagnose the adrenal injury.
