Splenic rotation as demonstrated by 99mTc SCOL.

The spleen is free to move around on its pedicle, since it is not fixed in the abdomen. We describe the case of a woman who demonstrated a temporary rotation of the spleen 90 degrees from its usual axis as shown by liver-spleen scintigraphy using technetium Tc-99m sulfur colloid (99mTc SCOL). The reason for this rotation is discussed. Other previously reported causes of splenic displacement are also reviewed.
