A woman in her early 60s presented with multiple transient neurological symptoms over the course of 20 months, including transient loss of power to her right lower limb. Initial workup with CT brain scan, carotid dopplers and ECG revealed no abnormality; however, MRI of the brain suggested recent ischaemic events in separate cortical territories. Subsequent transoesophageal echocardiogram revealed a large mobile mass histologically confirmed to be an atrial myxoma. This case highlights the challenges in diagnosing atrial myxomas and the importance of thorough workup including cardiac imaging for suspected cerebrovascular events. It also underscores the role of brain MRI when clinical suspicion for a cerebrovascular event persists despite a normal CT scan.
一名60岁出头的女性在20个月内出现了多种短暂性神经症状，包括右下肢短暂性无力。最初进行的脑部CT扫描、颈动脉多普勒检查和心电图检查均未发现异常；然而，脑部MRI显示在不同的皮质区域有近期缺血性事件。随后的经食管超声心动图显示有一个大的可移动肿块，组织学检查证实为心房黏液瘤。该病例突出了诊断心房黏液瘤的挑战以及对疑似脑血管事件进行全面检查（包括心脏成像）的重要性。它还强调了尽管CT扫描正常，但当临床怀疑存在脑血管事件时，脑部MRI的作用。
