【摘要】：目的探讨多层螺旋CT对肾上腺节细胞神经瘤的诊断价值。方法搜集经手术病理证实的16例肾上腺节细胞神经瘤,回顾性分析其CT表现。结果 16例中男10例,女6例,年龄3.5岁~59岁,15例位于右侧肾上腺,1例位于左侧肾上腺,所有病灶境界清楚,大小在2.8~8.3 cm之间;6例病灶内可见斑点状钙化,1例病灶内见较多的条状钙化;成人14例,平扫时CT值约26~35 HU,动脉期病灶呈轻度强化,CT值升高20 HU;儿童2例,平扫CT值约42~46 HU,增强后呈明显强化;15例右侧肾上腺病灶中,有3例包绕下腔静脉约1/4周长,但下腔静脉无明显变窄,有9例与下腔静脉相邻,交界面平直,另3例与下腔静脉间尚有脂肪间隙。结论 CT平扫及增强扫描能很好显示肾上腺节细胞神经瘤的影像学特点,对肾上腺节细胞神经瘤的诊断及鉴别诊断有重要价值。
[Abstract]:Objective to evaluate the value of multi-slice spiral CT in the diagnosis of adrenal ganglioneuroma. Methods CT findings of 16 cases of adrenal ganglioneuroma confirmed by operation and pathology were analyzed retrospectively. Results among the 16 cases, 10 were male and 6 female, and 15 were located in the right adrenal gland of 15 patients aged 3.5 years or 59 years, 1 case was located in the left adrenal gland, and the boundary of all the lesions was clear. The size of the lesions was between 2.8 ~ 8.3 cm in 6 cases, and in 1 case, there were more stripe calcification in 1 case, in 14 cases, the CT value was about 2635 HUduring plain scan, and in the arterial phase, the CT value was increased slightly by 20 HUU, and in 2 cases in children, the CT value was increased slightly in the arterial phase, and in 2 cases in the children, the CT value was about 2635 HUU on plain scan. The CT value of plain scan was about 42 ~ 46 HU.Among the 15 cases of right adrenal lesions, 3 cases were wrapped around the inferior vena cava about 1 / 4 weeks long, but the inferior vena cava was not obviously narrowed, and 9 cases were adjacent to the inferior vena cava, and the interface was straight. In the other 3 cases, there was fat space between the inferior vena cava and the inferior vena cava. Conclusion CT plain scan and contrast-enhanced scan can show the imaging features of adrenal ganglioneuroma and have important value in the diagnosis and differential diagnosis of adrenal ganglioneuroma.
