becquerel sign

Full Definition

Becquerel sign, also known as Cullen's sign, is the appearance of periumbilical bruising that suggests retroperitoneal or intraperitoneal hemorrhage. This clinical finding typically appears hours to days after the initial injury and indicates significant internal bleeding. The sign is named after the bluish discoloration that develops around the navel area. In trauma surgery documentation, this finding supports clinical suspicion of abdominal injury requiring urgent intervention.

Usage

Usage note: Often confused with Grey Turner sign (flank ecchymosis). Ensure proper anatomical localization in documentation.
