Match the following distinctive abdominal and gastrointestinal physical examination signs with their corresponding underlying pathophysiological mechanism or specific clinical etiology.
- Cruveilhier-Baumgarten signRecanalization of a fetal vessel due to severe portosystemic shunting
- Carnett signSomatic nerve irritation or focal myofascial pathology localized to the abdominal wall
- Kehr signPhrenic nerve referred pain secondary to subdiaphragmatic blood or fluid accumulation
- Cullen signTracking of retroperitoneal hemorrhage along the gastrohepatic and falciform ligaments
- Courvoisier signChronically elevated intraluminal pressure causing biliary distention without acute inflammation
Cevap
Cruveilhier-Baumgarten matches portosystemic shunting; Carnett matches abdominal wall pathology; Kehr matches subdiaphragmatic irritation/phrenic referral; Cullen matches tracking retroperitoneal hemorrhage; Courvoisier matches chronic non-inflammatory biliary distention.
Each physical examination finding correlates with a specific pathophysiological mechanism. The Cruveilhier-Baumgarten sign indicates portal hypertension via umbilical vein recanalization. Carnett sign differentiates abdominal wall pain from visceral pain. Kehr sign represents phrenic nerve referred pain from diaphragmatic irritation. Cullen sign is periumbilical ecchymosis from tracking retroperitoneal blood. Courvoisier sign is a palpable, non-tender gallbladder due to chronic malignant distal biliary obstruction.
