| 摘 要： | 目的:探讨眼眶肌锥内血管外皮细胞瘤(HPC)的CT及MRI表现和病理组织学特点,旨在提高对HPC的认识。方法:结合文献复习,回顾性分析1例经手术病理证实的HPC影像学表现、病理组织学特点、治疗及预后。结果:HPC的CT表现为眼眶内软组织密度;MRI表现以等T1信号、长T2信号为主,内见特征性多发细小流空信号,眼内肌及视神经明显受压,球后脂肪间隙存在。增强扫描:病变呈不均匀强化。结论:深入了解HPC的CT及MRI表现和病理组织学特点,对HPC的诊断、治疗和预后具有重要价值。

| Abstract: | Objective: To investigate the orbital muscle cone hemangiopericytoma(HPC) CT and MRI manifestations and pathologic characteristics, in order to improve the understanding of HPC. Methods: The literatures review, review findings, pathologic characteristics, treatment and prognosis of HPC images in 1 case proved by operation and pathology. Results: HPC CT showed soft tissue density, MRI performance with the T1 signal, T2 signal, see feature multiple small flow void signal, intraocular muscle and optic nerve were compressed, existence, fat gap ball after enhanced scanning lesions showed homogeneous enhancement. Conclusion: In depth understanding of CT and MRI manifestations and pathologic features of HPC, it has significant value in diagnosis, treatment and prognosis of HPC. |
