The utility of magnetic resonance angiography is sometimes limited in the diagnostic workup of cerebral aneurysms with low flow and/or partial thrombosis when weighed against digital subtraction angiography. We present the case of a rare superior cerebellar artery giant, partially thrombosed aneurysm in which additional i.v. contrast-enhanced MRA sequences were comparable to digital subtraction angiography. It demonstrated not only the exact spatial resolution and correct anatomical relation but also the hemodynamics which were confirmed by intraoperative Doppler ultrasound. This report supports the feasibility and utility of i.v. contrast-enhanced MRA for posterior fossa giant cerebral aneurysm management.
与数字减影血管造影相比，磁共振血管造影在诊断低流量和/或部分血栓形成的脑动脉瘤时，其效用有时会受到限制。我们报告了一例罕见的小脑上动脉巨大、部分血栓形成的动脉瘤病例，其中额外的静脉注射对比增强磁共振血管造影序列与数字减影血管造影相当。它不仅显示了精确的空间分辨率和正确的解剖关系，还显示了血流动力学情况，术中多普勒超声证实了这一点。本报告支持静脉注射对比增强磁共振血管造影在处理后颅窝巨大脑动脉瘤方面的可行性和效用。
