Abstract
We describe our experience with follow-up MR imaging and MR spectroscopy in two patients after embolization of meningiomas without subsequent surgery. In both patients there was a marked reduction in tumor size and a decrease in contrast enhancement associated with spectroscopic signs of fatty degeneration. We did not observe regrowth; however, in one patient with incomplete angiographic devascularization, residual vital tumor tissue was seen at follow-up examinations.
摘要
我们描述了两例未进行后续手术的脑膜瘤栓塞术后患者的磁共振成像（MR）随访及磁共振波谱分析（MRS）经验。两例患者肿瘤大小均显著缩小，对比增强减弱，并伴有脂肪变性的波谱学表现。我们未观察到肿瘤复发；然而，其中一例患者血管造影去血管化不完全，随访检查发现有残留的存活肿瘤组织。
