Ischaemic stroke is a rare manifestation of hypercoagulability induced by underlying malignancy. It is proposed that paraneoplastic non-bacterial thrombotic endocarditis (NBTE) is the most common cause, predisposing to the formation of friable valvular lesions composed of platelets and fibrin that embolize commonly. Pancreas, gallbladder, stomach, colon and gynaecological malignancies have all been associated with NBTE. We describe a female patient who presented to our facility with syncope and limb weakness. Magnetic resonance imaging of the brain revealed ischaemic strokes in both the anterior and posterior circulation. Further investigation revealed a pelvic mass that was biopsy proven to be ovarian malignancy. Prognosis is heavily reliant on disease stage, thus diagnostic clues suggesting the possibility of underlying malignancy in the presentation of stroke should prompt a thorough investigation to exclude malignancy.
缺血性中风是潜在恶性肿瘤引起的高凝状态的一种罕见表现。有人提出,副肿瘤性非细菌性血栓性心内膜炎(NBTE)是最常见的原因,易导致由血小板和纤维蛋白组成的易碎瓣膜病变形成,这些病变通常会发生栓塞。胰腺、胆囊、胃、结肠和妇科恶性肿瘤都与NBTE有关。我们描述了一名女性患者,她因晕厥和肢体无力前来我院就诊。脑部磁共振成像显示前循环和后循环均有缺血性中风。进一步检查发现盆腔有一肿块,活检证实为卵巢恶性肿瘤。预后很大程度上取决于疾病分期,因此在中风表现中提示潜在恶性肿瘤可能性的诊断线索应促使进行全面检查以排除恶性肿瘤。
