A 45-year old woman presented with a 5-month history of coughing, eight months after surgery for post-tubercular fibrosis with bronchiectasis. Upon computerized tomography (CT) scanning, a sponge-like structure was seen in the pneumonectomy cavity near the stump of the right main bronchus. Bronchoscopic examination revealed a whitish mass blocking the right main bronchial stump which, upon attempted retrieval, yielded long threads of cotton fibres from a retained surgical gauze. The gossypiboma was removed surgically and the patient became symptom-free. Although rare after thoracic surgery, gossypibomas need to be considered in symptoms following surgery.
