We describe an 80-year-old woman with intraventricular silicone oil mimicking traumatic pathology upon presentation to the emergency department after a ground-level fall. Intraventricular migration of silicone oil from prior intraocular endotamponade is rare having only been described in a handful of case reports. While it has a unique and characteristic appearance on imaging, intraventricular silicone oil can be confused with intraventricular hemorrhage or calcified ventricular neoplasms. Recognition and differentiation of intraventricular silicone oil from more sinister pathology is essential for the radiologist, neurologist and neurosurgeon and can be done with routine head CT scan. We discuss the imaging findings of intraventricular silicone oil and review the current understanding of this unusual phenomenon.
我们描述了一名80岁女性，在平地摔倒后被送往急诊科时，其脑室内硅油酷似创伤性病变。既往眼内填塞术后硅油发生脑室内迁移的情况罕见，仅有少数病例报告对此进行过描述。虽然硅油在影像学上有独特的特征性表现，但脑室内硅油可能会与脑室内出血或钙化的脑室肿瘤相混淆。对于放射科医生、神经科医生和神经外科医生而言，识别脑室内硅油并将其与更严重的病变区分开来至关重要，而这可以通过常规头部CT扫描来完成。我们讨论了脑室内硅油的影像学表现，并回顾了对这一不寻常现象的当前认识。
