Abstract
Imaging of a 29-year-old man with seizures showed a frontal lobe mass with curvilinear narrow calcifications, cystic components and multiple flow-voids. An AVM was considered. A DSA confirmed the hypervascular nature of the lesion. It was resected and microscopic examination showed an anaplastic oligodendroglioma remarkable for a diffuse and hypertrophic vasculature with areas of frank vascular proliferation. The marked vascularity seen on the MRI, the gyriform calcifications and the cystic degeneration are all features which can be encountered in an AVM. This case illustrates that highly vascular malignant gliomas can simulate vascular lesions by radiology and may require an angiogram for diagnosis.
摘要
一位 29 岁癫痫患者的影像学检查显示额叶有一肿块，有曲线形的窄钙化、囊性成分和多个流空信号。考虑为动静脉畸形。DSA 证实了病变的高度血管化性质。肿瘤被切除，显微镜检查显示弥漫性和肥厚性血管为特征的间变性少突胶质细胞瘤，有明显的血管增生区域。MRI 上看到的明显血管化、脑回状钙化和囊性变性都是动静脉畸形中可能遇到的特征。本例说明高度血管化的恶性胶质瘤可以通过影像学表现模拟血管病变，可能需要进行血管造影以明确诊断。
