Abstract:	We report a case of a nine-year-old boy with clinical evidence of foreign body (FB) aspiration with 3 months of delay in diagnosis. The bronchoscopy found soft tissue FB with surrounding inflamed granulation tissue at the entrance to the lateral segmental bronchus. Repeated attempts to remove the FB with flexible forceps were unsuccessful due to friable FB and granulation tissue. Ablation of the granulation tissue using nitrous oxide cryotherapy was then successfully performed and the distal and organic FB was extracted. Early diagnosis is important for minimizing granulation tissue development which complicates FB removal. Cryotherapy with a flexible bronchoscope is an option if organic FB cannot be removed using conventional bronchoscopic instrumentation.
