摘要
目的探讨1例脑膜血管瘤病变(MA)伴发颅内动脉瘤的临床特征及治疗策略。方法回顾性分析中山大学附属第一医院神经外科收治的1例形成颅内动脉瘤的MA患者的临床资料,实施急诊开颅大脑中动脉瘤夹闭、颅内血肿清除术,并将手术中动脉瘤周围脑膜脑组织做病理学检查。结果 MA伴发颅内动脉瘤患者镜检提示脑膜增厚,梭形细胞围绕脑膜和皮质内增生的血管周围形成环状、栅栏状结构。免疫组化结果示增生的血管及血管周围成纤维细胞样梭形细胞弥漫性vimentin阳性;增生的血管内皮细胞CD99、CD34阳性;病灶内残存胶质细胞示神经胶质原纤维酸性蛋白质阳性。结论 MA伴发动脉瘤形成的脑膜血管瘤病罕见,患者脑皮质血管畸形,血管条件差,动脉瘤形状极不规则,出血风险较高,可显微外科手术切除受累脑膜脑组织并夹闭动脉瘤。
Objective To investigate the clinical features and therapeutic strategies of one patient with meningioangiomatosis （ MA ） complicated with intracranial aneurysm formation. Methods The clinical data of one patient with aneurysm-formed MA admitted to the Department of Neurosurgery,the First Affiliated Hospital of Sun Yat-sen University was analyzed retrospectively. The patient received emergency craniotomy and middle cerebral artery aneurysm clipping and evacuation of intracranial hematoma. The meningeal tissue around the aneurysm was taken for pathological examination. Results Microscopy revealed meningeal thickening in the patient with MA accompanied with intracranial aneurysm. Spindle cells around the meninges and perivascular tissue of cortical hyperplasia formed an annular and fence-like structure. The results of immunohistochemistry showed the hyperplastic vessels and perivascular fibroblast like spindle cells diffuse vimentin-positive;the hyperplastic vascular endothelial cells CD99,CD34 were positive;and the residual glial cells in the lesions showed glial fibrillary acidic protein positive. Conclusion MA complicated with intracranial aneurysm is rare. The vascular condition is poor. The shape of aneurysm is irregular,and the risk of bleeding is high. Excise the involved meningeal tissue and clip the aneurysm with microsurgical operation is the resonable treatment.
