Overview

An x-ray may be helpful in the diagnosis of Löffler syndrome. Findings on an x-ray suggestive of Löffler syndrome include migratory densities. Chest x-ray usually shows abnormal shadows that can be unilateral or bilateral. Generally, densities are peripheral and present with both interstitial and alveolar pattern (at the same time), they are a few centimeters in diameter, and are transient, migratory, and disappear completely within 2-4 weeks. Pleural effusions is not common in Loeffler syndrome, but there are reports of pleural effusion in patients with drug-induced pulmonary eosinophilia. (nitrofurantoin, valproic acid)

X Ray

An x-ray may be helpful in the diagnosis of Löffler syndrome. Findings on an x-ray suggestive of/diagnostic of Löffler syndrome include:

• Chest x-ray usually shows abnormal shadows that can be unilateral or bilateral.
• Generally peripheral densities
• Present with both interstitial and alveolar pattern (at the same time).
• Usually a few centimeters in diameter, but larger areas of consolidation are possible
• Generally transient, migratory, and disappear completely within 2-4 weeks.
• Pleural effusions is not common in Loeffler syndrome, but there are reports of pleural effusion in patients with drug-induced pulmonary eosinophilia. (nitrofurantoin, valproic acid)
