Neck and Bilateral Shoulder Pain After Vomiting: Likely Esophageal Perforation Until Proven Otherwise
This patient requires immediate evaluation for esophageal perforation (Boerhaave syndrome), a life-threatening emergency that classically presents with neck and shoulder pain following forceful vomiting.
Critical Red Flag Recognition
The temporal relationship between vomiting and subsequent neck/bilateral shoulder pain 2 days later is highly concerning for:
Primary Concern: Esophageal Perforation
- Boerhaave syndrome occurs from forceful vomiting causing transmural esophageal tear
- Pain radiates to neck and shoulders via diaphragmatic irritation (referred pain through phrenic nerve C3-C5 distribution) 1
- The 2-day delay suggests contained perforation with developing mediastinitis or pleural contamination
- Mortality approaches 50% if diagnosis delayed beyond 24 hours
Immediate Clinical Assessment Required
Vital signs to check NOW:
- Fever (suggests mediastinitis/empyema)
- Tachycardia >100 bpm (seen in 26-year-old with similar presentation) 2
- Tachypnea or hypoxia
- Hypotension (septic shock)
Physical examination must include:
- Hamman's sign (mediastinal crunching sound with heartbeat)
- Decreased or absent breath sounds (pneumothorax, pleural effusion) 2
- Subcutaneous emphysema in neck/chest wall
- Abdominal tenderness (peritonitis if intra-abdominal extension)
Diagnostic Algorithm
Step 1: Immediate Imaging (Within Hours)
Chest radiograph (3 views) is the initial study 3, 4:
- Look for pneumomediastinum, subcutaneous emphysema, pleural effusion, pneumothorax
- Sensitivity only 50-60% for esophageal perforation
Step 2: Definitive Imaging if Radiograph Abnormal or High Clinical Suspicion
CT chest with oral contrast is diagnostic study of choice 2:
- Identifies perforation site, extent of contamination, mediastinal air/fluid
- Guides surgical planning
- Order immediately—do not wait for "routine" scheduling
Step 3: If CT Negative but Suspicion Remains High
- Water-soluble contrast esophagram
- Esophagoscopy (with caution—can worsen small perforations)
Alternative Diagnoses to Consider (Lower Priority)
Musculoskeletal Causes
While cervical spine pathology can cause bilateral shoulder pain 4, 5, the post-vomiting timing makes this unlikely unless:
- Pre-existing cervical radiculopathy exacerbated by vomiting mechanics
- However, cervical pathology does NOT cause fever, tachycardia, or respiratory symptoms
Pneumothorax/Pneumomediastinum
- Can occur from forceful vomiting (spontaneous pneumomediastinum)
- Usually self-limited but requires imaging exclusion 2
Gastric Distension with Diaphragmatic Irritation
- Postprandial referred shoulder pain described 1
- But 2-day persistence after vomiting makes benign gastric distension extremely unlikely
Management Pathway
If Esophageal Perforation Confirmed:
- NPO immediately
- Broad-spectrum IV antibiotics (cover oral flora: anaerobes, streptococci)
- IV fluid resuscitation
- Immediate surgical consultation (thoracic surgery)
- Treatment depends on timing:
- <24 hours: Primary repair possible
24 hours: Often requires drainage, débridement, possible esophageal diversion
If Imaging Negative for Perforation:
- Consider pneumomediastinum (conservative management)
- Evaluate for cervical spine pathology only if neurologic symptoms present 4
- Consider musculoskeletal causes with MRI cervical spine if pain persists and no red flags 4
Critical Pitfalls to Avoid
Do not dismiss this as "muscle strain from vomiting" without imaging—the bilateral distribution and 2-day persistence demand exclusion of life-threatening causes.
Do not order cervical spine imaging first—chest pathology takes precedence given the clinical context 3, 4.
Do not delay imaging for "observation"—esophageal perforation mortality increases exponentially with time.
Do not assume normal vital signs exclude serious pathology—early contained perforations may have subtle findings initially 2.
