摘　　要：目的总结外伤性肾上腺血肿的影像学表现,提高肾上腺血肿的诊断准确率。方法回顾分析我院经临床随访证实的21例外伤性肾上腺血肿的影像学资料。结果 21例外伤性肾上腺血肿均在外伤后1周内行CT检查,其中2例行增强扫描,2例行MRI检查。CT平扫表现为肾上腺区类圆形、长椭圆形等高密度影、低密度影;病灶周边脂肪层浑浊,内见线条影;多伴有胸腹部脏器的损伤。增强扫描示病灶各期扫描均未见明显强化。MRI表现为T1WI为等信号或略高信号,T2WI为高信号,边界欠清晰。随访观察可见肾上腺区的病灶逐渐缩小,密度减低直至消失。结论外伤性肾上腺血肿的CT和MRI表现具有一定特征性,能够明确诊断并为临床提供准确的诊疗依据。Objective：to summarize the imaging findings of traumatic adrenal hematoma,improve the diagnosis accura-cy of adrenal hematoma. Methods：retrospective analysis confirmed by clinical follow-up imaging data of 21 cases of trau-matic adrenal hematoma. Results：21 cases of traumatic adrenal hematoma were CT examination 1 weeks after trauma,2 of whom underwent enhancement scanning,2 routine MRI. CT scan of adrenal area circular,elliptic high-density shadow, such as low density;Within the lesion fat layer surrounding the turbidity,see the shadow lines;With the chest viscera damage. Enhanced scan lesions in each phase scanning has not been obviously improved. MRI manifestation for T1WI sig-nal or slightly high signal,for high T2WI signal,boundary less clear. Visible in the adrenal lesions were gradually nar-rowed,density decreases until it disappeared. Conclusion：CT and MRI manifestation of traumatic adrenal hematoma has certain characteristic,can provide accurate diagnosis and clinical diagnosis and treatment.
