Congenital cyst adenoid malformation (CCAM) is a rare congenital malformation occurring in approximately 1–4 in 100,000 births. It is classified into five subtypes with type 1 CCAM is most common subtype. The diagnosis of CCAM is usually made in infancy, and it is rare in adolescents and adults. We report a 15-year-old female, who presented in pediatric outpatient department with a history of recurrent cough since infancy. On the basis of clinical examination, provisional diagnosis of asthma was considered and patient was started on inhaled corticosteroid and long-term β2 agonist. Lung function of the patient revealed low forced expiratory volume-1 s but without bronchodilator reversibility. Therefore, alternative diagnosis was suspected, and the patient was further evaluated with X-ray chest and high resolution computed tomography thorax. Based on radiological findings, a final diagnosis of CCAM was established. The case was highly unusual due to its atypical and late age of presentation. Acquaintance about this condition benefit clinician in making differential diagnosis of recurrent cough.
