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。
Objective: To investigate CT and MRI features and histopathological features of orbital pyramidal hemangiopericytoma (HPC) in order to improve the understanding of HPC. Methods: According to the literature review, 1 case of pathologically confirmed HPC, histopathological features, treatment and prognosis were retrospectively analyzed. Results: CT showed the soft tissue density in the orbit. The MRI manifestations were mainly T1 signal and T2 signal. The characteristic multinuclear small flow signals were observed in the HPC. The intraocular muscles and the optic nerve were obviously compressed and the posterior fat space existed. Enhanced scan: uneven lesions were enhanced. Conclusion: A thorough understanding of CT and MRI features of HPC and histopathological features of HPC diagnosis, treatment and prognosis of great value.
