Which sign is associated with retroperitoneal bleeding presenting as flank bruising?

• A. Kehr Sign
• B. Cullen Sign
• C. Beck's Triad
• D. Grey-Turner Sign

Answer: (D)

Retroperitoneal bleeding can show up as flank bruising because blood tracks through the retroperitoneal space and extends to the skin along the flanks, creating what is known as Grey-Turner sign. This flank ecchymosis is often a late finding and can accompany conditions like pancreatitis, trauma, or other retroperitoneal hemorrhages. In contrast, Kehr sign is referred shoulder pain from diaphragmatic irritation due to intraperitoneal blood, Cullen sign is periumbilical ecchymosis from intraperitoneal bleeding, and Beck's triad points to cardiac tamponade. So the sign associated with retroperitoneal bleeding presenting as flank bruising is Grey-Turner sign.
