PURPOSE
The aim of this study was to characterize the CT features of retroperitoneal neurilemmoma.
METHODS
The CT findings were reviewed in seven patients with retroperitoneal neurilemmoma.
RESULTS
All of the tumours were well-demarcated round or oval masses. In five cases, heterogeneous contrast enhancement was noted after contrast medium administration. Areas of minimal enhancement reflected diffuse edema in one tumour. Areas without definite enhancement represented prominent cyst formation in three tumours. There were three cases with tumour calcification (two with punctate calcification and one with mottled calcification).
CONCLUSION
CT findings may suggest the diagnosis of retroperitoneal neurilemmoma preoperatively.
目的
本研究的目的是描述腹膜后神经鞘瘤的CT特征。
方法
回顾性分析7例腹膜后神经鞘瘤患者的CT表现。
结果
所有肿瘤均为边界清晰的圆形或椭圆形肿块。5例在注入造影剂后表现为不均匀强化。1例肿瘤内强化程度最低的区域提示弥漫性水肿。3例肿瘤内无强化区域提示有显著的囊肿形成。3例有肿瘤钙化（2例为点状钙化，1例为斑片状钙化）。
结论
CT表现有助于术前诊断腹膜后神经鞘瘤。
