目的探讨肾上腺髓质脂肪瘤的CT表现特征及诊断价值。方法回顾性分析经手术病理证实的9例肾上腺髓质脂肪瘤的CT表现特征,并与B超、手术结果进行对照。结果 9例肾上腺髓质脂肪瘤均为含脂肪组织的圆形或类圆形混杂密度肿块,其内可见条索状高密度影。增强扫描可见肿瘤内条索状高密度分隔轻度强化,脂肪组织无强化。CT对该病的定性率(88.9%)明显高于B超(55.6%),提示CT是目前肾上腺髓质脂肪瘤影像诊断的主要方法。结论肾上腺髓质脂肪瘤的CT影像表现具有一定的特征,根据肿瘤生长部位、形态、密度及增强特征结合临床表现,有助于提高术前诊断准确率。CT是诊断肾上腺髓质脂肪瘤的主要影像学方法。
Objective To investigate the CT features and diagnostic value of adrenal medullary lipoma. Methods The CT features of 9 cases with adrenal medullary lipoma confirmed by surgery and pathology were retrospectively analyzed. The CT findings were compared with those of B ultrasound and surgical results. Results Nine cases of adrenal medullary lipoma were adipose tissue with round or round hybrid density mass, which can be seen within the cord-like high-density film. Enhanced scan visible intracavitary cord-like high-density separation of mild enhancement, no enhancement of adipose tissue. CT qualitative rate of the disease (88.9%) was significantly higher than B-ultrasound (55.6%), suggesting that CT is the main method of imaging diagnosis of adrenal lipoma. Conclusion CT images of adrenal medullary lipoma have certain characteristics. According to the tumor growth site, morphology, density and enhanced features combined with clinical manifestations, it helps to improve the accuracy of preoperative diagnosis. CT is the main imaging method for the diagnosis of adrenal lipoma.
