title: Fluctuating symptomatic cryofibrinogenaemia in a patient with left atrial myxoma.
abstract: We report a case of left atrial myxoma associated with a fluctuating level of cryofibrinogen. Her initial symptoms and signs were consistent with primary cryofibrinogenaemia, but a repeat episode occurred without the cryofibrinogen being detectable. A more typically embolic cerebro-vascular accident (CVA) occurred, with the subsequent discovery of the patient's myxoma. The cryofibrinogen was again present but it disappeared with resection of the myxoma. We propose that the degree of activation of the coagulation system around the myxoma fluctuated, causing variable conversion of fibrinogen to fibrin, so that at times partially cross-linked fibrin(ogen) resulted in cryofibrinogen, but at other times frank emboli from more complete clotting occurred.
