Aretained surgical sponge (gossypiboma, textiloma) is a rare complication of surgery. Radiological appearances of textilomas change according to the type of the reaction they cause in the body. Patients are usually asymptomatic for a long time after the operation. Most reports in the literature relate to the US and CT appearances of textilomas in the abdomen. However, there are a few reports describing findings of intrathoracic textilomas. We report the radiologic findings of intrathoracic textilomas in three cases.
