Middle Lobe Syndrome is a term that refers to a persistent or recurrent collapse of a lung lobe, especially the right middle lobe. A 66-year-old woman presented with chronic cough with sputum and recurrent attacks of pneumonia. She was treated with antibiotics. Chest CT-scan showed a left lobe atelectasis and multiple foci of bronchiectasis. Bronchoscopy revealed a patent left lower lobe bronchus. In conclusions, middle lobe syndrome can rarely affect left lower lobe. It should be kept in mind in the differential diagnosis of recurrent pneumonia.
