Retained intra- thoracic surgical pack mimicking as recurrent aspergilloma.

An intrathoracic gossypiboma is a rare condition. We are reporting a case of intrathoracicgossypiboma which was misdiagnosed as a recurrent aspergilloma. In our patient, the gossypiboma manifested as a pleural- based extra pulmonary mass which had a large contact area with the pleura and it displayed an extra pulmonary location. A retained surgical swab (gossypiboma) is a rare but an important complication of an intra- thoracic surgery. The diagnosis is usually overlooked, as in our case, resulting in delay of treatment, complications and a prolonged hospitalization.
