A self-insertion of the styrofoam in urinary bladder is relatively rare. The diagnosis might be missed due to concealing the history of self-insertion of the foreign body and the presence of gas in the bladder on CT and MRI. Younger patients with lower urinary tract symptoms should raise the index of suspicion.
