肾上腺节细胞神经瘤的CT表现及其血液动力学特征

目的探讨肾上腺节细胞神经瘤的CT表现及血液动力学特征。方法选择2014年3月-2 017年1月以肾上腺节细胞神经瘤患者25例作为对象,设为观察组。所有患者均经过手术病理组织检查最终确诊,手术前均经Light Speed VCT64层螺旋CT检查扫描仪检查,层厚0.625mm、螺距0.984mm,所有患者行CT平扫后随后30s、70s及3min动态增强扫描,分析肾上腺细胞神经瘤的CT表现;选择同期入院健康体检者50例,设为对照组。采用日本生产HSTECNM KN型血清自动分析仪测定两组肾上腺节神经瘤血液动力学水平,采用SPSS Pear son相关性分析软件对肾上腺节细胞神经瘤的CT检出率与血液动力学进行相关性分析。结果 25例肾上腺节细胞神经瘤患者均经过手术病理检查确诊,CT检查确诊24例,确诊率为96.00%(P>0.05);CT下12例表现为肾上腺区椭圆形,7例分叶状,6例不规则状,边界相对清楚,肿块直径大小为(2.4~9.3) cm。增强CT下10例呈轻度强化,其中延迟性强化4例,静脉期均匀或不均匀强化5例,1例不规则状肿瘤生长,向周围间隙延伸;观察组CVP、SVR水平,均高于对照组(P<0.05);观察组CO、CI水平,均低于对照组(P <0.05);两组MAP水平差异无统计学意义(P> 0.05);SPSS Pearson相关性分析结果表明:CT在肾上腺节细胞神经瘤检出率与CVP和SVR水平呈正相关性(P<0.05);CT在肾上腺节细胞神经瘤检出率与CO与CI水平呈负相关性(P<0.05)。结论将CT用于肾上腺节细胞神经瘤患者中能获得较高检出率,具有一定的特征性,且与血液动力学具有明显的相关性,能为临床诊疗提供影像学依据和参考。

CT Findings and Hemodynamic Characteristics of Adrenal Ganglioneuroma

Objective To investigate the CT findings and hemodynamics of adrenal ganglioneuroma. Methods Twenty-five patients with adrenal ganglion cell neuroma were selected from March 2014 to January 2017 as the observation group. All patients were finally diagnosed by surgical pathological examination. All patients were examined by Light Speed VCT64-slice spiral CT scan. The thickness of the layer was 0.625 mm and the pitch was 0.984 mm. All patients underwent CT scan and then dynamically enhanced for 30 s, 70 s and 3 min. Scanning and analysis of CT findings of adrenal cell neuroma;50 patients who were admitted to the hospital for healthy physical examination at the same time were selected as the control group. The hemodynamics of two groups of adrenal nodal neuroma were measured by HSTECNM KN automatic analyzer in Japan. The correlation between CT detection rate and hemodynamics of adrenal ganglioneuroma was analyzed by SPSS Pearson correlation analysis software. Results Twenty-five patients with adrenal ganglion neuroma were diagnosed by surgical pathology. All patients underwent CT examination before pathological examination. The final diagnosis was 24 cases, the diagnosis rate was 96.00%(P>0.05). The 12 cases under CT showed the adrenal area. Elliptical, 7 cases of lobulated, 6 cases of irregular shape, the boundary is relatively clear, the diameter of the mass is(2.4~9.3) cm. Ten cases underwent enhanced CT, mild enhancement, 4 cases of delayed enhancement, 5 cases of uniform or uneven enhancement of venous period, 1 case of irregular tumor growth, extending to the surrounding space;CVP and SVR levels in the observation group were higher than The control group(P<0.05);the CO and CI levels in the observation group were lower than those in the control group(P<0.05). There was no significant difference in the MAP between the observation group and the control group(P>0.05). The results of SPSS Pearson correlation analysis The results showed that the detection rate of CT in adrenal ganglion cell neuroma was positively correlated with CVP and SVR levels(P<0.05). The detection rate of CT in adrenal ganglion cell neuroma was negatively correlated with CO and CI(P<0.05). Conclusion CT can be used in patients with adrenal ganglion cell neuroma to obtain a high detection rate, which has certain characteristics and has obvious correlation with hemodynamics. It can provide imaging basis and reference for clinical diagnosis and treatment.
