Loeffler's syndrome: an interesting case report.

Loeffler's syndrome is an acute pneumonia with an unclear cause. One fourth of Loeffler's syndrome patients are idiopathic, although the most common etiologic causes include parasites. Asymptomatic form is usually a reversible, self-limited disease, which does not require a specific treatment regimen. We presented a 17-year-old young man with diagnosis of Loeffler syndrome.
