LEFT ATRIAL TUMOR MIMICKING PULMONARY-EMBOLISM

Primary cardiac tumours have been described as great imitators. They a re rare, and clinical presentations are diverse. Diagnosis is usually made by two-dimensional echocardiography. The present case report desc ribes a case where a left atrial fibrosarcoma eluded diagnosis by echo cardiography, and was eventually demonstrated by computed tomography. Management was complicated by the presence of persistent mismatch demo nstrated by ventilation-perfusion lung scans. The likely mechanism und erlying this phenomenon is discussed.
