Macewen sign
A sign to detect hydrocephalus and brain abscess. Percussion (tapping) on the skull at a particular spot (near the junction of the frontal, temporal and parietal bones) yields an unusually resonant sound in the presence of hydrocephalus or a brain abscess. Named for Sir William Macewen (1848-1924), a surgeon in Glascow, Scotland who also described Macewen’s operation for inguinal hernia.

on percussion of the skull behind the junction of the frontal, temporal, and parietal bones, there is a more resonant note than normal in internal hydrocephalus and cerebral abscess. Called also cracked-pot sound and cranial cracked-pot sound.
