Question

9 year-old boy with sudden onset of unilateral facial swelling. What’s the diagnosis?

Answer

Answer: Acute Parotitis

Viral parotitis
- Usually bilateral swelling without warmth or erythema; typically a benign course
- 85% of cases occur in children <15 years old
- Common causes: Influenza, Para-influenza, and Coxsackie; Rarely Paromyxovirus (Mumps) due to vaccination programs
- Treat conservatively; sialagogues to stimulate gland drainage (lemon drops or orange juice), warm compresses, or local massage.
Bacterial parotitis
- Commonly presents with unilateral pain, induration, erythema, and tenderness; 20-50% mortality!
- Risk factors: chronic illness, age > 60, recent surgery, and dehydration
- Treatment: Antibiotics (covering oral flora) and certain cases may require surgical intervention
- Lack of improvement within 48 hours requires CT scan to exclude abscess and IV antibiotics

Bonus Trivia: U.S. President Garfield died from parotitis after becoming dehydrated following abdominal surgery
