Difficulty: HardPhysical Examination Findings

Match each classic abdominal physical examination finding with its corresponding underlying anatomical or pathophysiological mechanism.

  • Courvoisier signGradual malignant obstruction of the biliary tree distal to the cystic duct
  • Kehr signDiaphragmatic irritation with referred pain mediated by the C3-C5 nerve roots
  • Cruveilhier-Baumgarten murmurPortosystemic collateralization involving a recanalized vein within the falciform ligament
  • Grey Turner signExtravasation of hemorrhagic exudate from the retroperitoneum along the transversalis and quadratus lumborum fascia

Answer

Courvoisier sign corresponds to gradual malignant biliary obstruction; Kehr sign corresponds to phrenic nerve-mediated diaphragmatic irritation; Cruveilhier-Baumgarten murmur corresponds to portosystemic shunting via the falciform ligament; Grey Turner sign corresponds to retroperitoneal hemorrhage tracking along the flank fascia.
Each physical examination finding is a direct result of specific anatomical relationships and pathophysiologic processes. Courvoisier sign occurs because a non-inflamed gallbladder can distend under the pressure of a distal malignant obstruction, unlike a fibrosed gallbladder in gallstone disease. Kehr sign is a classic example of referred pain where diaphragmatic irritation is interpreted by the brain as somatic pain in the C3-C5 distribution. The Cruveilhier-Baumgarten murmur results from turbulent flow in portosystemic collaterals, specifically the umbilical vein within the falciform ligament. Grey Turner sign represents the physical manifestation of retroperitoneal hemorrhage migrating to the subcutaneous tissues of the flank.

Step-by-Step Solution

1
Analyze Courvoisier sign
Matched to gradual malignant obstruction of the biliary tree distal to the cystic duct.
The sign describes a distended, non-tender gallbladder. This occurs in chronic distal obstruction (usually malignant), without the fibrotic scarring seen in chronic inflammatory cholecystitis.
2
Analyze Kehr sign
Matched to diaphragmatic irritation with referred pain mediated by the C3-C5 nerve roots.
Blood or exudate in the subdiaphragmatic space irritates the phrenic nerve, referring pain to the corresponding C3-C5 sensory dermatomes at the shoulder.
3
Analyze Cruveilhier-Baumgarten murmur
Matched to portosystemic collateralization involving a recanalized vein within the falciform ligament.
Portal hypertension forces blood into the systemic circulation via the umbilical vein remnant, which is structurally located within the falciform ligament.
4
Analyze Grey Turner sign
Matched to extravasation of hemorrhagic exudate from the retroperitoneum along the transversalis and quadratus lumborum fascia.
Hemorrhagic fluid from retroperitoneal organs (such as the pancreas) tracks laterally to the flanks, presenting superficially as ecchymosis.
