Actinomycosis, a rare temporal bone infection caused by Actinomyces israelii, requires histopathology for diagnosis. Treatment involves surgery and long-term penicillin therapy.

Area of Science:

Otolaryngology
Infectious Diseases
Microbiology

Background:

Actinomycosis is a bacterial infection caused by Actinomyces israelii, an anaerobic, filamentous, Gram-positive bacterium.
While commonly affecting the cervico-facial region, actinomycosis of the temporal bone is exceptionally rare, with only 24 previous English literature reports.

Observation:

Temporal bone actinomycosis diagnosis is challenging and has historically relied on histopathological examination.
Clinical diagnosis may involve identifying sulphur granules, but this is not consistently definitive for temporal bone cases.

Findings:

Histopathology remains the gold standard for diagnosing temporal bone actinomycosis.
Actinomyces israelii is the causative agent identified in these rare temporal bone infections.

Implications:

Early and accurate diagnosis through histopathology is crucial for effective management.
A combined therapeutic approach of surgical intervention followed by prolonged penicillin administration is effective for temporal bone actinomycosis.
