Left shoulder pain that indicates a spleen injury is called?

• A. Grey Turner's sign
• B. Kehr's sign
• C. Pulmonary edema
• D. Cor pulmonale

Answer: (B)

Kehr's sign. This is left shoulder pain caused by diaphragmatic irritation from blood in the peritoneal cavity, most often due to splenic injury or rupture after trauma. The irritation stimulates the phrenic nerve (C3–C5), so the referred pain is felt at the left shoulder tip rather than where the injury actually is. Other signs listed aren’t related to spleen injury: Grey Turner's sign is flank bruising from retroperitoneal bleeding, while pulmonary edema and cor pulmonale involve the lungs and heart, not diaphragmatic irritation from splenic trauma.
