TRANSITORY INFILTRATION OF THE LUNG WITH EOSINOPHILIA

Abstract

Since Löffler in 1931 first drew attention to a condition characterized by transitory infiltration of the lung and eosinophilia, increasing interest has been paid to this symptom complex by those engaged in the treatment of diseases of the lung. Löffler's syndrome consists of four cardinal signs which have been present in all the cases so far reported: signs of pulmonary disease on auscultation and percussion, the presence of a corresponding shadow in the roentgenogram, transience of the pulmonary signs and increase of the eosinophils in the blood. One hundred and five cases have so far been reported, 51 by Löffler¹himself. The importance of this condition, from the point of view of both differential diagnosis and prognosis, induces us to report a case which came under our observation. The patient was a woman aged 25, of the asthenic type, 5 feet 81/2 inches (174 cm.) tall and weighing 126
