Zorluk: OrtaPhysical Examination Findings

A group of medical residents is reviewing classic abdominal physical examination findings and their underlying pathophysiological or anatomic mechanisms. Match each eponymous physical examination sign with the mechanism that best explains its clinical presentation.

  • Cullen signExtravasation of hemorrhagic exudate tracking along anatomical fascial planes to the periumbilical subcutaneous tissue
  • Kehr signIrritation of the inferior diaphragmatic surface mediated via the C3-C5 nerve roots
  • Murphy signDescent of an inflamed hepatobiliary structure contacting the examiner's fingers during deep inspiration
  • Courvoisier signMalignant obstruction of the common bile duct resulting in painless biliary tree distention
  • Rovsing signTransmission of localized pressure leading to stretching of the right-sided inflamed parietal peritoneum

Cevap

Cullen sign matches with extravasation of hemorrhagic exudate to periumbilical tissue; Kehr sign matches with C3-C5 nerve root mediated diaphragmatic irritation; Murphy sign matches with descent of an inflamed hepatobiliary structure during inspiration; Courvoisier sign matches with malignant obstruction of the common bile duct causing painless distention; Rovsing sign matches with transmission of localized pressure stretching the right-sided parietal peritoneum.
Each physical examination sign represents a distinct anatomical or pathophysiological process. Cullen sign is periumbilical ecchymosis due to tracking of retroperitoneal or intraperitoneal hemorrhage along fascial planes. Kehr sign is left shoulder pain referred via the phrenic nerve from irritation of the inferior surface of the diaphragm, classic for splenic rupture. Murphy sign is an inspiratory arrest caused by an inflamed gallbladder descending during respiration to meet the palpating hand. Courvoisier sign is a palpable, non-tender gallbladder caused by chronic, malignant obstruction of the common bile duct. Rovsing sign relies on the transmission of manual pressure from the left lower quadrant across the abdominal cavity, irritating the inflamed right-sided parietal peritoneum overlying the appendix.

Adım Adım Çözüm

1
Analyze each eponymous physical examination sign to determine its clinical definition and presentation.
Identified the signs: Cullen (periumbilical ecchymosis), Kehr (referred left shoulder pain), Murphy (inspiratory arrest on right upper quadrant palpation), Courvoisier (palpable painless gallbladder with jaundice), and Rovsing (right lower quadrant pain elicited upon left lower quadrant palpation).
Accurate definition of the eponymous signs is required before mapping them to their underlying physiology.
2
Correlate each defined physical sign with its underlying pathophysiological or anatomical mechanism.
Mapped the corresponding anatomical pathways: retroperitoneal tracking to periumbilical area (Cullen), phrenic nerve referral (Kehr), diaphragmatic excursion (Murphy), distal malignant obstruction (Courvoisier), and indirect pressure transmission across the abdomen (Rovsing).
Understanding the anatomical mechanism allows for accurate diagnostic interpretation of physical findings in clinical practice.
