Rovsing's sign

Medical condition

Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), is a sign of appendicitis. If palpation of the left lower quadrant of a person's abdomen increases the pain felt in the right lower quadrant, the patient is said to have a positive Rovsing's sign and may have appendicitis. The phenomenon was first described by Swedish surgeon Emil Samuel Perman (1856–1945) writing in the journal Hygiea in 1904.
