Case Report: Diffuse Cystic Bronchiectasis Associated with Left Microtia and External Auditory Canal Atresia: A Very Rare Coincidence

Objective: To present a case in which diffuse cystic bronchiectasis was associated with left microtia/external auditory canal atresia. Clinical Presentation: A 10-year-old girl suffering from cough, fever, dyspnea and sputum for 6 months was transferred to our clinic due to the diagnosis of bronchopneumonia. She had recurrent episodes of bronchopneumonia. On examination, left microtia and left external auditory canal atresia were detected. Thorax CT revealed diffuse cystic bronchiectasis on the left lung. Radiological examination showed atresia of the left external auditory canal. We could not find any etiopathological reason causing bronchiectasis. Intervention: The patient underwent left pneumonectomy and postoperative histopathology was reported as bronchiectasis. Conclusion: This report shows a unique case in which an association of diffuse cystic bronchiectasis and left microtia/external auditory canal atresia was observed. Hence in newborns with microtia and/or external auditory canal atresia, the probability of development of bronchiectasis should be borne in mind and such patients should be followed up more carefully regarding this rare association.
