Question:

Which of the following statements about the imaging features of gossypibomas are wrong?
1. Gossypibomas is always seen radioopaque within the roentgenograms.
2. Gossypibomas is seen radioopaque if retained surgical sponge contains radio-opaque marker.
3. At sonography, gossypibomas can produce sharp posterior acoustic shadowing.
4. At sonography, gossypibomas can be seen as cystic or complex masses.
5. At CT scans gossypibomas are seen as spiculated mass lesions.





Answer:

The correct answers for the question "Which of the following statements about the imaging features of gossypibomas are wrong?" are:

1. Gossypibomas is always seen radioopaque within the roentgenograms.

5. At CT scans gossypibomas are seen as spiculated mass lesions.



Explanation
a)    Gossypibomas are seen radioopaque within the roentgenograms only if they contain sponge with radioopaque marker. [Roentgenograms are useful if retained sponge contains radio-opaque marker. But such sponges are not widely used in practice.]

b)    Gossypibomas are seen radioopaque within the roentgenograms if they contain sponge with radioopaque marker. [Roentgenograms are useful if retained sponge contains radio-opaque marker. But such sponges are not widely used in practice.]

c)    Sonographically gossypibomas can be seen as sharp posterior acoustic shadowing. [At sonography, retained surgical sponge most commonly is seen as echogenic anterior stripe and a sharply delineated posterior acoustic shadowing]

d)    At sonography, gossypibomas also can be seen as cystic or complex masses. [Other sonographic appearances reported in the literature are cystic, hypoechoic and complex masses which are quite nonspecific.]

e)    At CT scans gossypibomas are not seen as spiculated mass. [On CT and MRI scans, retained sponges are demonstrated as well-marginated round or oval mass lesions]

Abstract
We report a case of retained surgical sponge in the breast with its sonographic and magnetic resonance (MR) imaging findings. Striped and spotted low signal intensity structures seen within the lesion on T2 weighted MR imaging was characteristic. Sonographic examination also was helpful with the appearance of strong posterior acoustic shadowing at the lesion. It is extremely rare, to see a gossypiboma in the breast. A high degree of suspicion and imaging findings are very important for the diagnosis.
