tissue in the right lower quadrant. The appendix is generally the prime suspect, although other pathology can also give a "positive" Rovsing's sign. If left lower quadrant pressure by the examiner leads only to left-sided pain or pain on both the left and right sides, then there may be some other pathologic etiology. This may include causes relating to the bladder, uterus, ascending (right) colon, fallopian tubes, ovaries, or other structures. The eponym Rovsing sign is also used in patients with horseshoe kidney, consisting of abdominal pain, nausea, and vomiting with hyperextension of the spine. While Rovsing's test is frequently performed in suspicion of appendicitis, its sensitivity and specificity have not been adequately evaluated, and is considered by some to be an antiquated examination test.
