Gossypiboma or a retained surgical sponge is a rare but avoidable surgical complication. It leads to considerable morbidity and at times even mortality. We report a case of a 24-year-old lady who presented one month after a Caesarean operation with complaints of fever, pain in abdomen, and vomiting. After the clinical examination a possibility of a retained surgical sponge was entertained. However a CT scan of abdomen revealed the complete diagnosis and helped in treating the patient surgically with a successful outcome. A review of the literature and all the relevant issues in the management of such a case have been discussed.
