Cavernous malformations, low-flow vascular lesions predominantly found in the brain and occasionally in the spinal cord, can be congenital or acquired, with acquired forms often being single and congenital ones multiple. While many patients remain asymptomatic, hemorrhage from these lesions can lead to significant neurological symptoms. This case report describes a 35-year-old female with a hemorrhagic lesion in the right precentral gyrus, initially challenging to diagnose due to atypical imaging findings. Advanced magnetic resonance imaging (MRI) techniques, including dynamic susceptibility contrast perfusion and advanced diffusion methods, were employed to distinguish the lesion from other hemorrhagic conditions and suggested that the lesion is benign in nature. Follow-up MRI revealed regression of the hemorrhage and typical characteristics of a cavernous malformation. The case underscores the utility of advanced diffusion MRI techniques in differentiating hemorrhagic cavernous malformations from other pathologies, particularly in complex cases where conventional imaging may fall short.
海绵状血管畸形是一种主要出现在脑部、偶尔也见于脊髓的低流量血管病变，可为先天性或后天性，后天性形式通常为单发，先天性形式则多为多发。虽然许多患者没有症状，但这些病变出血可导致严重的神经症状。本病例报告描述了一名35岁女性，其右侧中央前回有一个出血性病变，最初因非典型影像学表现而诊断困难。采用了先进的磁共振成像（MRI）技术，包括动态磁敏感对比灌注和先进的扩散方法，以将该病变与其他出血性疾病区分开来，并提示该病变本质上是良性的。随访MRI显示出血消退以及海绵状血管畸形的典型特征。该病例强调了先进的扩散MRI技术在鉴别出血性海绵状血管畸形与其他病变方面的作用，特别是在传统成像可能不足的复杂病例中。
