Summary
Actinomycosis, a rare bacterial infection, can manifest subtly after dental procedures. This case highlights a parotid abscess caused by Actinomyces israelii, successfully treated with a multi-phase antibiotic regimen.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Oral Surgery
Background:
- Actinomycosis is a chronic bacterial infection caused by Actinomyces species.
- Cervicofacial actinomycosis often follows dental procedures, like mandibular molar extraction.
- Initial symptoms can be subtle, delaying diagnosis.
Observation:
- A 29-year-old male presented with a parotid mass post-molar extraction.
- Imaging revealed a parotid abscess; biopsy confirmed Actinomyces infection.
- Initial antibiotic and steroid treatment failed, leading to relapse with fistula formation.
Findings:
- A recurrent parotid abscess due to Actinomyces israelii was observed.
- Successful treatment involved a sequential intravenous and oral antibiotic course.
- The patient remained asymptomatic after a one-year follow-up.
Implications:
- This case underscores the importance of considering actinomycosis in parotid abscesses, especially post-dental procedures.
- Aggressive and prolonged antibiotic therapy may be necessary for complete resolution.
- Early diagnosis and appropriate treatment are crucial to prevent complications and relapse.
