Unsuspected Pulmonary Emboli in Pediatric Oncology Patients: Detection With MDCT

Abstract

PE are unsuspected findings at nearly 2% of routine thoracic MDCT examinations of pediatric oncology patients. More than one half of PE were not detected prospectively at initial CT image interpretation, but lack of diagnosis and treatment did not appear to have a negative influence on patient outcome. Underlying coagulation disorder and a history of deep venous thrombosis or PE were risk factors for unsuspected PE.
