目的探讨MRI、CT影像学检查对上颌窦海绵状血管瘤的诊断价值。方法对11例鼻内镜下行上颌窦肿瘤切除术,病理确诊为海绵状血管瘤患者的MRI、CT影像学资料进行回顾性分析,并复习相关文献。结果 CT均表现为受累鼻窦有不同程度的膨大,窦壁骨质明显受压变形、变薄,骨质不连续并形成大小不一的缺损。其中9例MRT1WI呈中等信号,10例MRT2WI呈高信号。8例动态增强扫描,均呈渐进性强化及蜂窝状或斑驳状表现。结果显示MRI、CT改变,结合病史,术前能提示上颌窦海绵状血管瘤的诊断。结论 MRI和CT特点对上颌窦血管瘤的术前诊断有重要意义,能为手术方案的制订提供有价值的信息。
Objective To investigate the diagnostic value of MRI and CT imaging in maxillary sinus cavernous hemangioma. Methods 11 cases of maxillary sinus resection under endoscopic sinus surgery, pathological diagnosis of cavernous hemangiomas MRI and CT imaging data were retrospectively analyzed and reviewed the relevant literature. Results CT showed sinusoids infiltration of varying degrees of expansion, sinus wall compression was significantly deformed, thinning, the bone is not continuous and the formation of different sizes of defects. Among them, 9 cases showed moderate MRT1WI signal and 10 cases MRT2WI showed high signal. 8 cases of dynamic contrast-enhanced scanning, showed progressive enhancement and honeycomb or mottled performance. The results showed MRI, CT changes, combined with medical history, preoperative can prompt the diagnosis of maxillary sinus cavernous hemangioma. Conclusion The MRI and CT features are of great significance for the preoperative diagnosis of maxillary sinus hemangiomas and can provide valuable information for the development of surgical plans.
