摘要
目的探讨纵隔节细胞神经瘤的CT表现特征,以提高其诊断准确性。方法回顾性分析经手术病理证实的纵隔节细胞神经瘤9例,术前均行CT平扫及增强扫描。结果纵隔节细胞神经瘤的CT表现为边缘光滑清晰的肿块影,多呈类圆形或椭圆形,密度低且均匀,平扫密度低于胸大肌,部分肿块内可见点状钙化灶(3/9),增强扫描多数肿块呈轻度均匀强化(8/9),强化后密度仍低于胸大肌,少数可见条带状不均匀强化(1/9)。结论纵隔节细胞神经瘤CT表现具有一定特征性,有助于术前诊断及手术方案的制定。
Objective To investigate CT features of mediastinal ganglioneuroma and improve diagnostic accuracy. Methods Unenhanced and contrast-enhanced pre-operafive CT of 9 patients with histologically confirmed mediastinal ganglioneuromas was analyzed retrospectively. Results The CT characteristics of mediastinal ganglioneuromas included well-defined round or elliptical masses with homogeneous density lower than that of pectoralis major muscle on unenhanced images. Scattered punctate calcifications were found in 3/9 masses. There was slightly homogeneous or heterogeneous contrast enhancement in the tumor less than that ofpectoralis major muscle. Conclusion Mediastinal ganglioneuromas have some specific CT characteristics, which may assist pre-operative diagnosis and surgical planning.
