SMALL-CELL CARCINOMA AS THE CAUSE FOR A NONDIAGNOSTIC V Q LUNG-SCAN/

Pulmonary thromboembolism (PTE) is a common cause of morbidity and mor tality in an emergency department patient population, The advent of ve ntilation/perfusion (V/Q) lung scanning and the more recent publicatio n of well-controlled analysis of results, such as the Prospective Inve stigation in Pulmonary Embolism Diagnosis (PIOPED) data, have provided the clinician with effective diagnostic algorithms to use in suggesti ve cases, However, there are disorders other than PTE, such as broncho genic carcinoma, that can cause characteristic abnormalities in V/Q sc anning, One such case is described in this report.
