本文报告1例原发性颅内间变性血管周细胞瘤(haemangiopericytomas,HPC)伴全身多发转移的患者,患者为52岁男性,14年前以头痛起病,头颅磁共振提示后枕叶占位,行开颅病变切除术。术后随访期间发现原位肿瘤多次复发,并伴肝脏、髂骨、胸椎等...本文报告1例原发性颅内间变性血管周细胞瘤(haemangiopericytomas,HPC)伴全身多发转移的患者,患者为52岁男性,14年前以头痛起病,头颅磁共振提示后枕叶占位,行开颅病变切除术。术后随访期间发现原位肿瘤多次复发,并伴肝脏、髂骨、胸椎等多处转移。手术全切(gross total resection,GTR)是该病例的主要治疗方式,术后通过多次放疗、介入栓塞、高强度聚焦超声等多种综合治疗方案,使病变得到有效控制。原发性颅内血管周细胞瘤是一种罕见的神经系统肿瘤,间变性HPC具有高复发及颅内外转移的特点,综合性治疗是主要手段。展开更多
目的总结瘤样脱髓鞘病(tumefactive demyelinating lesions, TDLs)与瘤样原发性中枢神经系统血管炎(tumefactive primary angiitis of the central nervous system, TPACNS)的MRI特点,为临床鉴别提供重要参考依据。方法选择2009年12月至...目的总结瘤样脱髓鞘病(tumefactive demyelinating lesions, TDLs)与瘤样原发性中枢神经系统血管炎(tumefactive primary angiitis of the central nervous system, TPACNS)的MRI特点,为临床鉴别提供重要参考依据。方法选择2009年12月至2018年3月于衡水市第四人民医院和解放军总医院第六医学中心住院治疗的经病理证实的TPACNS患者19例和TDLs患者17例,回顾性分析二者的MRI特点。结果 TPACNS和TDLs的发病平均年龄分别为(32.0±13.7)岁和(39.3±12.8)岁,差异无统计学意义(P=0.113)。TPACNS平均病程(42.2±7.7)周,明显长于TDLs组[(4.0±2.7)周],差异有统计学意义(P=0.033)。TPACNS以慢性起病常见,TDLs则以亚急性起病常见,差异有统计学意义(P<0.05)。TPACNS组病灶累及皮质或皮质下明显多于TDLs组,病灶累及脑干明显少于TDLs组。所有TPACNS的T1WI、T2WI病灶均为不均匀病灶,而所有TDLs均呈均匀病灶。TPACNS组中12例的DWI呈病灶中心低信号、周边高信号,TDLs组则无。TPACNS组中12例呈现不规则、不连续、不均匀强化,可表现为不规则肠腔样强化、不规则不均一弥漫样强化、不规则不连续壁薄厚不均匀强化。TDLs组强化方式多样。结论 TDLs和TPACNS患者的MRI影像学有一定特征,累及部位、T1WI、T2WI及DWI信号特点、病灶均匀度、MRI增强图像,对于鉴别TDLs和TPACNS有重大提示意义。展开更多

This study reported a 53-year-old male patient with massive metastases in almost whole vertebras. Splenectomy, chemotherapy and radiotherapy were performed. The patient survived 6 months after diagnosis.展开更多
