Abstract

The majority of meningiomas are slow-growing benign tumors that can potentially be highly vascularized; however, acute hemorrhagic onset is rare. Herein, we describe two patients who presented with disturbance of consciousness and severe hemiplegia due to spontaneous hemorrhage from a falx atypical meningioma. A 49-year-old female presenting with a sudden disturbance of consciousness and severe left hemiplegia was found to have a falx meningioma and acute hemorrhage. Emergent resection achieved neurological relief and tumor control. A 60-year-old female with aphasia and severe right hemiplegia also had falx meningioma and hematoma, and successfully treated by emergent resection. Tumor was diagnosed as atypical meningioma in both cases. Both patients achieved mid-term tumor control for 4 and 7 years. Both patients were treated successfully with emergent surgical resection, and neurological relief and mid-term tumor control (7 and 4 years, respectively) were achieved. Given this success, immediate surgical resection with hematoma evacuation should be considered an acceptable therapeutic option for acute hemorrhagic atypical meningioma.

急性出血性非典型脑膜瘤:两例紧急切除术后肿瘤得到中期控制并保留神经功能的病例报告》(Areport of Two Cases with Emergent Resection Achieving Mid-Term Tumor Control and Neurological Preservation.
大多数脑膜瘤都是生长缓慢的良性肿瘤,有可能是高血管性的;然而,急性出血起病却很少见。在此,我们描述了两名因镰状非典型脑膜瘤自发性出血而出现意识障碍和严重偏瘫的患者。一名 49 岁的女性患者突然出现意识障碍和严重的左侧偏瘫,被发现患有镰状脑膜瘤和急性出血。紧急切除后,患者的神经症状得到缓解,肿瘤也得到控制。一名 60 岁女性患者也患有镰状脑膜瘤和血肿,并伴有失语和严重的右侧偏瘫。两例患者的肿瘤均被诊断为非典型脑膜瘤。两名患者的肿瘤分别在 4 年和 7 年后得到中期控制。两名患者均成功接受了急诊手术切除治疗,神经功能得到缓解,中期肿瘤得到控制(分别为 7 年和 4 年)。有鉴于此,对于急性出血性非典型脑膜瘤,立即手术切除并清除血肿应被视为一种可接受的治疗方案。
