摘要
目的：探讨盆部神经源性肿瘤的螺旋CT表现特征。方法：回顾性分析经手术病理证实的盆部神经源性肿瘤13例。13例均行螺旋CT平扫和增强扫描。结果：神经鞘瘤5例（其中恶性3例），神经纤维瘤5例，神经母细胞瘤1例，节细胞性神经瘤1例，恶性副节细胞瘤1例。2例起源于骶丛，经由骶孔向盆腔内生长；2例起源于盆腔，其中1例源于膀胱，1例位于膀胱直肠陷窝；直肠腹膜外间隙6例；膀胱腹膜外间隙3例。盆部神经源性肿瘤表现：体积较大，形态规则或不规则，边界清楚或局部不清楚，密度不均匀，内可见囊变区和钙化灶；增强扫描呈边缘强化/不均匀强化。结论：螺旋CT对盆部神经源性肿瘤的诊断有较大价值。
Abstract
Objective: To investigate the spiral CT features of pelvic neurogenic tumors. Materials and Methods: Consecutive 13 cases of pelvic neurogenic tumors proven by surgery and pathology were reviewed. All of these patients underwent plain and contrast-enhancement CT scan. Results: Thirteen cases included 5 neurilemmomas(3 malignant cases included), 5 neurofibromas, 1 neuroblastoma, 1 ganglioneuroma, 1 malignant paraganglioma. In the 13 cases, 2 cases derived from plexus sacralis, 2 cases located in the pelvic peritoneal space, 6 cases located in the pelvic extraperitoneal space, and 3 cases located in the vesica extraperitoneal space. Neurogenic tumors showed regular/irregular masses with big volume, well-defined/ill-defined margin, heterogeneous density, cyst formation, calcifications, and peripheral/heterogeneous contrast enhancement. Conclusion： Spiral CT can demonstrate the features of the pelvic neurogenic tumors and has diagnostic value.
