An 8-year-old boy presented with recurrent chest pain and haemoptysis since 3 years of age. He had taken multiple courses of antitubercular treatment without any symptomatic relief. His chest x-ray showed opacity consistent with right sided lung collapse. Further detailed work-up including high-resolution CT scan of thorax, pulmonary angiogram and radionucleide study confirmed intrathoracic gastrogenic cyst. Complete control of symptoms was achieved with pantaprazole 40 mg once daily.
