Abstract

Pulmonary magnetic resonance imaging (MRI) has historically been challenging because of the low proton density of the lungs and respiratory and susceptibility artifacts; however, recent advancements in technology have made it increasingly useful for the diagnosis and monitoring of lung diseases, such as lung cancer and chronic obstructive pulmonary disease. No previous studies have specifically focused on the use of pulmonary MRI in eosinophilic lung disease. This case report presents the first case of Löffler’s syndrome incidentally detected in abdominal MRI. The patient was diagnosed with Löffler’s syndrome based on pulmonary opacities and increased peripheral blood eosinophil counts. Followup computed tomography revealed that pulmonary opacities were resolved. In this case, MRI distinguished between a solid nodule and the surrounding ground-glass opacity. Thus, our report can be considered representative of magnetic resonance (MR) findings for Löffler’s syndrome. Our observations also highlight the importance of increasing radiological familiarity with MR findings in various pulmonary diseases.
