A case of multifocal stroke—the first presentation of underlying ovarian malignancy

Abstract

Abstract 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.
