Macewen's sign or Macewen sign (/məˈkjuːɪn/) is a sign used to help to diagnose hydrocephalus^[1] (accumulation of excess cerebrospinal fluid) and brain abscesses. Tapping (percussion) the skull near the junction of the frontal, temporal and parietal bones will produce cracked pot sound.Positive test is indication of separated sutures.This is due to raised intracranial tension.

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. Mcevan sign seen in alcohol intoxication is different
