We report a case of trigonal cavernous malformation (CM) radiologically mimicking meningioma. The computed tomographic (CT) head angiography and magnetic resonance imaging (MRI) showed a partially calcified lesion with slight contrast enhancement located in the area of the left atrium of lateral ventricle. The lesion was completely removed using microsurgery with a parieto-occipital transcortical approach. The resected mass was histologically confirmed as CM. CM should be considered as differential diagnosis in case of the atrial mass lesion due to lack of hemosiderin ring characteristically seen other seated CM.
我们报告一例放射学表现类似脑膜瘤的三角区海绵状畸形(CM)病例。头颅计算机断层扫描(CT)血管造影和磁共振成像(MRI)显示,位于左侧脑室前角区域有一个部分钙化的病变,有轻微的对比增强。采用顶枕经皮质入路显微手术将病变完全切除。切除的肿块经组织学证实为CM。由于缺乏其他部位CM典型可见的含铁血黄素环,对于心房肿块病变,应将CM视为鉴别诊断之一。
