Match each classic clinical presentation to the most likely surgical diagnosis.

Periumbilical pain migrating to the right lower quadrantAcute appendicitis
Right upper quadrant pain radiating to the right scapulaAcute cholecystitis
Sudden onset of severe pain with a rigid, board-like abdomenPerforated peptic ulcer
Severe abdominal pain out of proportion to physical examination findingsAcute mesenteric ischemia

Answer

Periumbilical migrating pain matches Acute appendicitis; RUQ pain radiating to the right scapula matches Acute cholecystitis; Sudden severe pain with a rigid abdomen matches Perforated peptic ulcer; Pain out of proportion to exam matches Acute mesenteric ischemia.

Each clinical presentation describes a pathognomonic symptom pattern for common acute abdominal emergencies. Rapid pattern recognition of these distinct presentations is critical for appropriate triage and surgical decision-making.

Step-by-Step Solution

Analyze the first presentation: periumbilical pain migrating to the right lower quadrant.

This matches acute appendicitis.

This represents the typical visceral to somatic shift of appendicular pain.

Analyze the second presentation: right upper quadrant pain radiating to the right scapula.

This matches acute cholecystitis.

Gallbladder inflammation often causes referred pain to the right scapula, known as Boas sign.

Analyze the third presentation: sudden severe pain with a rigid, board-like abdomen.

This matches perforated peptic ulcer.

Rapid spillage of gastric acid causes diffuse chemical peritonitis and severe abdominal wall rigidity.

Analyze the fourth presentation: pain out of proportion to physical exam.

This matches acute mesenteric ischemia.

Ischemic bowel initially presents with severe visceral pain prior to the development of frank peritonitis.
