目的:探讨眼眶内血管外皮细胞瘤影像学表现,提高对本病影像学特征的认识。方法:报道1例经手术、病理证实的右侧眼眶内血管外皮细胞瘤,对其CT平扫、MRI平扫及强化表现进行分析。结果:肿瘤CT表现为右侧眶内上方球后团块状软组织密度影。MRI表现为右侧眼眶内上方球后团块状T1WI等及稍低信号,T2WI稍高信号影,动态增强扫描,动脉期及实质期有明显强化。结论:运用多种影像学检查方法,可提高对眼眶内血管外皮细胞瘤的认识,做出准确的诊断。
Objective: To investigate the imaging features of orbital hemangiopericytoma and to improve the understanding of the imaging features of this disease. Methods: One case of right orbital hemangiopericytoma confirmed by operation and pathology was reported. CT scan, MRI plain scan and enhancement were performed. Results: The CT findings of the tumor were massive soft tissue density of the right orbital upper ball. MRI manifestations of the right orbital supraclavicular mass after T1WI and so on and slightly lower signal, T2WI slightly higher signal, dynamic contrast-enhanced MRI, arterial phase and substantive significantly enhanced. Conclusion: The use of a variety of imaging methods can improve the understanding of intraorbital hemangiopericytoma and make accurate diagnosis.
