Medical Eponyms

  • Pulsatile spleen (lien verberans) also know as Gerhardt sign (1882); Sailer sign (1928) first described by Tulp in 1641

Nothing in medical art is better known than that the spleen pulsates continuously, if violently moved by the arteries. But for this organ itself to strike the ribs so forcibly that the sound of the beating (lit. flogging, or whipping) may be heard from afar, that certainly is novel and, perchance hitherto unheard of.
