肾上腺节细胞神经瘤的超声特征与病理分析

The ultrasonographic features and pathological analysis of adrenal ganglioneuroma

目的探讨肾上腺节细胞神经瘤超声表现及病理特征以提高对该病诊断水平。方法回顾分析经手术病理证实的12例肾上腺节细胞神经瘤患者的超声及病理资料。重点观察病灶的部位、形态、大小、回声特点、有无钙化、彩色血流信号以及病灶与周围组织的关系。结果 12例中,9例发生在右侧肾上腺,3例发生在左侧肾上腺,均为单发,肿瘤直径1.8～12cm,多呈类圆形或椭圆形,部分呈不规则形或＂嵌入式＂生长,肿瘤均呈低回声,5例内部见强或高回声,病理证实为钙化,3例肿瘤可见少量点状彩色血流信号,12例肿瘤均与周围结构清晰。病理上肿瘤主要由神经节细胞及施旺细胞组成。结论肾上腺节细胞神经瘤的超声具有一定特征性,观察肿瘤生长部位、形态及回声特点,对该肿瘤的诊断具有重要价值。

Objective To explore the ultrasonography findings and pathological features of adrenal ganglioneuroma and to improve diagnostic level. Methods Ultrasonography appearance and clinical pathological data of 12 cases of primary adrenal ganglioneuroma were retrospectively analyzed. The location, shape, size, echo characteristics, with or without calcification, the color signal of blood flow and its neighboring structure relationship on ultrasound were analyzed. Results In 12 cases, 9 cases were found in the right adrenal gland and 3 cases in the left. All the tumors were solitary and the diameter was between 1.8 and 12 cm. The tumors were round or oval, some irregular or ＂embedded＂ growth. Echogenic focus were found in 5 cases which was pathologically confirmed calcification, 3 cases of tumor showed a small dot color flow signal, all tumors with clear boundaries around the surrounding tissue. Pathology of tumor was mainly composed of ganglion cells and Schwann cells. Conclusion Ultrasonography is of great value in the diagnosis of adrenal ganglioneuroma owing to some specific sonograms.
