目的:探讨肾上腺损伤的CT表现和鉴别诊断。方法:CT检查肾上腺损伤22例,其中平扫22例,增强扫描12例,随访CT 17例;MRI检查1例,B超检查12例。CT检查外伤后最短时间2 h,最长达7 d,平均19.8 h。回顾性分析其CT表现及影像特点。结果:22例肾上腺损伤,单侧21例(右侧15例,左侧6例),双侧1例。CT表现为平扫肾上腺增大6例,边缘凸起,密度不均;肾上腺肿块16例,呈圆形或卵圆形均匀增高或混杂密度。肾上腺周围脂肪囊内见密度增高线条状影及高密度模糊影15例。同侧膈脚增厚11例。增强扫描12例中,呈不均匀强化4例,环状强化8例。随访CT显示肾上腺形态基本正常,其中3例肾上腺区肿块吸收、消失。结论:CT检查对肾上腺损伤诊断及鉴别诊断具有重要意义。
Objective: To investigate the CT findings and differential diagnosis of adrenal injury. Methods: Twenty - two cases of adrenal injury were examined by CT, of which 22 cases were plain scan and 12 cases were enhanced scan. Follow - up CT was performed in 17 cases. MRI was performed in 1 case and in B - mode ultrasound in 12 cases. The shortest time after CT trauma was 2 h and the maximum was 7 d, with an average of 19.8 h. Retrospective analysis of CT findings and imaging features. Results: Twenty-two adrenal lesions were unilateral in 21 cases (right side in 15 cases, left side in 6 cases) and bilateral in 1 case. CT showed 6 cases of adrenal plain enlargement, the edge of the raised, uneven density; adrenal mass in 16 cases, a uniform round or oval or mixed density. Around the adrenal fat capsule, see the increased density of linear shadow and high-density blurred film 15 cases. Ipsilateral phrenic thickening in 11 cases. Enhanced scan in 12 cases, showed uneven enhancement in 4 cases, annular enhancement in 8 cases. Follow-up CT showed adrenal morphology was normal, including 3 cases of adrenal mass absorption, disappear. Conclusion: CT examination of adrenal injury diagnosis and differential diagnosis of great significance.
