Understanding Cullen's Sign | Clinical Significance and Causes

Cullen's sign is a distinctive clinical sign that appears as a bluish discoloration around the periumbilical region (belly button), often indicative of internal bleeding. It is a sign of hemoperitoneum (blood in the peritoneal cavity) and can be associated with serious underlying conditions, particularly those involving the abdomen.

In this video, we explore the clinical significance of Cullen's sign, its causes, and what it means for patient diagnosis and management. We also discuss the conditions that may lead to this sign, how it is diagnosed, and its role in emergency medicine and surgery.
