Recurrent pneumonia is a condition characterized by fever, infiltrative lesion and leukocytosis experienced at least twice in a year by the same patient. At least a one-month interval following the recovery between two episodes is necessary in order to distinguish slow-resolving pneumonias from this group (1). The most common causes in the unilateral liver lobe include foreign material aspiration, malignancy, bronchiectasis, sequestration, bronchogenic cyst and lymph node pressure. In multiple node involvement, the causes include central nervous system diseases, antibody and complement failure, cystic fibrosis, primary ciliary dyskinesia, asthma, ABPA and diabetes mellitus (2).
