Aneurysm of the membranous interventricular septum is an uncommon cardiac defect that is, on rare occasions, associated with embolic stroke. We describe here the case of an otherwise healthy, 41-year-old man who presented to the hospital with acute-onset confusion and left-sided body weakness attributed to a right middle cerebral artery ischemic stroke. He experienced a nearly complete resolution of deficits following systemic thrombolytic therapy. After an extensive workup, the presumed mechanism of stroke was a thromboembolus that originated in a massive aneurysm of the patient's membranous interventricular septum. Due to a perceived risk of surgical morbidity, the patient was managed conservatively with anticoagulation. He denied further events and reported nearly full function at follow-up.
膜性室间隔动脉瘤是一种罕见的心脏缺陷，在极少数情况下与栓塞性中风有关。我们在此描述一名41岁健康男性的病例，他因急性起病的意识模糊和左侧肢体无力入院，病因是右侧大脑中动脉缺血性中风。经全身溶栓治疗后，他的缺损几乎完全恢复。经过全面检查，推测中风的机制是血栓栓塞，起源于患者膜性室间隔的巨大动脉瘤。由于考虑到手术并发症的风险，对该患者采取抗凝保守治疗。他否认有进一步发作，并在随访中报告功能几乎完全恢复。
