II. Definition

  1. Painful Thyroiditis associated with Non-Viral Infection

III. Epidemiology

  1. Rare form of Painful Thyroiditis

IV. Causes

V. Risk Factors

  1. Immunocompromised patients
  2. Elderly
  3. Pre-existing Thyroid disease in up to 50%
  4. Congenital defect
    1. Persistent thyroglossal duct
    2. Piriform sinus fistula

VI. Symptoms

  1. Acute unilateral Neck Pain
  2. Symptoms provoked by neck extension
  3. Focal neck structure compression
    1. Dysphagia
    2. Dysphonia
    3. Stridor

VII. Signs

  1. High fever
  2. Erythematous skin overlying Thyroid
  3. Thyroid swollen and tender to palpation (focal or diffusely)
  4. Cervical Lymphadenopathy

VIII. Labs

  1. Thyroid Function Tests (TSH, Free T4)
    1. Variable abnormalities or may be euthyroid
    2. Patients return to euthyroid state after infection resolves
    3. Thyroid autoantibodies (if obtained) are absent
  2. C-Reactive Protein (C-RP) or Erythrocyte Sedimentation Rate (ESR) increased
  3. Complete Blood Count
    1. Leukocytosis with band forms
  4. Blood Cultures

IX. Diagnosis

  1. Thyroid Fine Needle Aspirate (Thyroid FNA)
    1. Send for Gram Stain and culture

X. Imaging

  1. First-Line
    1. CT Neck with contrast
  2. Alternative studies
    1. MRI Neck
    2. Lateral Neck Xray (may demonstrate soft tissue gas)

XI. Management

  1. Hospitalization
  2. Surgery Consultation if abscess drainage required
  3. Intravenous antibiotics to cover suspected organisms
    1. Nafcillin AND Gentamicin
    2. Third generation Cephalosporin

XII. Complications

  1. Septic Shock
  2. Airway obstruction
  3. Thyroid abscess
    1. Consider for fluctuant swelling
  4. Vocal Cord Paralysis
  5. Transient Hypothyroidism
