摘要

发育性静脉异常(DVA)是一种常见的脑血管变异,通常被认为是良性的,临床无症状。我们报告一个例外的情况下,症状性幕下DVA在一个9岁的孩子,成为临床明显后,轻微的头部创伤。病例报告:患者出现后颅窝受累的神经系统症状,包括头痛、恶心和共济失调。MRI显示右小脑半球有一簇异常扩张的髓质静脉,会聚成一个扩大的集静脉,符合DVA。发现明显的小脑水肿与检测到的血管畸形有关。患者保守治疗消肿和镇痛,导致症状迅速解决和完全恢复。结论:本病例表明,即使是轻微的头部创伤,也可能由于短暂的血流动力学障碍而没有血栓形成或出血,导致DVAs继发于明显的血管源性水肿而出现急性症状。我们的研究结果挑战了dva总是良性实体的看法,并要求进一步调查其创伤后病理生理学。

Trauma-Induced Cerebellar Edema: A Rare Presentation of Infratentorial Developmental Venous Anomaly in a Pediatric Patient.

Introduction: Developmental venous anomaly (DVA) is a common cerebral vascular variant, typically considered benign and clinically silent. We report an exceptional case of a symptomatic infratentorial DVA in a 9-year-old child that became clinically evident after a minor head trauma.

Case report: The patient presented with neurological symptoms indicative of posterior fossa involvement, including headache, nausea, and ataxia. MRI revealed a cluster of abnormally dilated medullary veins in the right cerebellar hemisphere converging into an enlarged collector vein, consistent with a DVA. Significant cerebellar edema was identified in association with detected vascular malformation. The patient was managed conservatively with antiedematous therapy and analgesics, which led to rapid resolution of symptoms and complete recovery.

Conclusion: This case demonstrates that DVAs can become acutely symptomatic secondary to significant vasogenic edema following even minor head trauma, likely due to transient hemodynamic disturbance without thrombosis or hemorrhage. Our findings challenge the perception of DVAs as invariably benign entities and warrant further investigation into their post-traumatic pathophysiology.

期刊介绍: Official publication of the Society for Research on the Cerebellum devoted to genetics of cerebellar ataxias, role of cerebellum in motor control and cognitive function, and amid an ageing population, diseases associated with cerebellar dysfunction. The Cerebellum is a central source for the latest developments in fundamental neurosciences including molecular and cellular biology; behavioural neurosciences and neurochemistry; genetics; fundamental and clinical neurophysiology; neurology and neuropathology; cognition and neuroimaging. The Cerebellum benefits neuroscientists in molecular and cellular biology; neurophysiologists; researchers in neurotransmission; neurologists; radiologists; paediatricians; neuropsychologists; students of neurology and psychiatry and others.
