Macewen's sign 1142079 220054286 2008-06-18T01:59:38Z Arcadian 104523 nav '''Macewen's sign''' is a sign used to help to diagnose [[hydrocephalus]] (accumulation of excess [[cerebrospinal fluid]]) and brain [[abscess]]es. Tapping ([[percussion, medical|percussion]]) the skull near the junction of the [[frontal bone|frontal]], [[temporal bone|temporal]] and [[parietal bone|parietal]] bones will produce a stronger [[resonant]] sound when either hydrocephalus or a brain abscess are present. The sign was discovered and described by Sir [[William Macewen]] (1848-1924), a surgeon and professor of the [[University of Glasgow]], [[Scotland]] who also described [[Macewen's operation]] for [[inguinal hernia]]. {{med-sign-stub}} {{Eponymous medical signs for nervous system}} [[Category:Neurology]] [[pl:Objaw Macewena]]
