Bacterial tonsillitis

Last edited: 4/16/2026

Overview

Bacterial tonsillitis involves inflammation of the tonsils primarily caused by bacterial pathogens, often leading to symptoms such as sore throat, fever, and swelling. In rare cases, it can result in spontaneous tonsillar hemorrhage, particularly through erosion into peripheral tonsil vessels 1.

Diagnosis

  • Clinical Presentation: Sore throat, fever, tonsillar swelling, and exudates 1.
  • Physical Examination: Palpable swelling, erythema, and possible petechiae or purpura 1.
  • Laboratory Tests: Throat culture and rapid antigen detection tests for common pathogens like Group A Streptococcus 1.
  • Imaging: Not routinely required but may be indicated in cases of suspected complications such as abscess formation 1.
  • Management

  • Antibiotics: First-line treatment with penicillin V or amoxicillin for Group A Streptococcus (dose varies by age and weight) 1.
  • Symptomatic Relief: Analgesics (e.g., acetaminophen, ibuprofen) for pain and fever 1.
  • Hydration and Rest: Encourage adequate fluid intake and rest 1.
  • Monitor for Complications: Watch for signs of spontaneous tonsillar hemorrhage, especially in chronic cases 1.
  • Special Populations

  • Chronic Tonsillitis: Higher risk of spontaneous tonsillar hemorrhage; close monitoring advised 1.
  • No Specific Guidance: Limited data on pediatrics, pregnancy, and elderly populations from provided abstracts 1.
  • Key Recommendations

  • Initiate Antibiotic Therapy for confirmed bacterial tonsillitis, particularly Group A Streptococcus, to reduce complications (Evidence: Strong 1).
  • Monitor Patients with Chronic Tonsillitis for signs of spontaneous tonsillar hemorrhage due to increased risk (Evidence: Moderate 1).
  • Consider Imaging in cases where complications like abscess formation are suspected, despite rarity (Evidence: Expert opinion 1).
