Clinical Differentiation of Costochondritis and Pericarditis

Costochondritis presents with reproducible chest wall tenderness on palpation of the costochondral junctions, while pericarditis presents with sharp, pleuritic chest pain that improves with sitting forward, often accompanied by a pericardial friction rub and characteristic ECG changes.

Key Distinguishing Features

Costochondritis 1

  • Pain characteristics: Localized to anterior chest wall, reproducible with direct palpation over costal cartilages
  • Physical examination: Tenderness at costochondral or chondrosternal joints is the hallmark finding
  • No systemic findings: Absence of fever, pericardial rub, or ECG changes
  • Demographics: More common in women (69%) and affects 30% of patients presenting with chest pain 2
  • Diagnostic approach: History and physical examination documenting reproducible pain by palpation is usually sufficient in young patients

Pericarditis 3, 4, 5

Diagnostic criteria require at least 2 of 4 findings:

  1. Pericarditic chest pain (≈90%): Sharp, pleuritic, worsens when supine, improves sitting up or leaning forward
  2. Pericardial friction rub (<30%): Audible on auscultation at left lower sternal border
  3. ECG changes (≈25-50%): Widespread ST-elevation with upward concavity and PR depression
  4. Pericardial effusion (≈60%): New or worsening effusion on echocardiography

Critical Clinical Distinctions

Pain Quality and Position

  • Costochondritis: Pain remains constant regardless of body position; worsens with chest wall movement or deep breathing
  • Pericarditis: Pain characteristically improves with sitting forward and worsens when supine 3

Physical Examination

  • Costochondritis: Positive palpation test—pressing on affected costochondral junctions reproduces the exact pain 1
  • Pericarditis: Palpation does not reproduce pain; may have pericardial friction rub (though present in <30% of cases) 5

Inflammatory Markers

  • Costochondritis: Normal inflammatory markers in most cases 2
  • Pericarditis: Elevated C-reactive protein (CRP) and ESR are common; troponin may be minimally elevated without worse prognosis 3

Age-Based Diagnostic Approach

For patients <35 years without cardiac risk factors:

  • Costochondritis can be diagnosed clinically with reproducible chest wall tenderness 1
  • Pericarditis requires ECG and consideration of echocardiography

For patients ≥35 years or with cardiac risk factors:

  • ECG is mandatory to exclude both pericarditis and coronary artery disease (present in 3-6% of patients with chest wall tenderness) 1
  • Consider chest radiograph and echocardiography
  • Acute MI rate is 6% in costochondritis patients vs 28% in other chest pain patients 2

Common Pitfalls

Do not assume chest wall tenderness excludes cardiac disease: Coronary artery disease coexists in 3-6% of patients with reproducible chest wall tenderness 1. Always obtain ECG in patients ≥35 years or with cardiac risk factors.

Do not miss pericarditis without a friction rub: The friction rub is present in <30% of pericarditis cases 5. Diagnosis relies on the constellation of clinical features, not a single finding.

Recognize myopericarditis: When pericarditis involves myocardial inflammation, troponin elevation is common and patients may have fatigue and exercise intolerance beyond typical pericarditis symptoms 3.

Imaging Considerations

  • Costochondritis: No imaging required for diagnosis; chest X-ray normal
  • Pericarditis: Echocardiography recommended to assess for effusion (present in ≈60%), though small effusions are most common 5. CMR useful if diagnostic uncertainty or to assess myocardial involvement 3
