[Brain abscess as a complication of ear malignancy: a case report]

Area of Science:

• Neurology
• Otolaryngology
• Oncology

Background:

• Ear infections are the primary cause of brain abscesses, often spreading via direct extension or preformed pathways to the central nervous system.
• Squamous cell carcinoma of the middle ear/mastoid is rare, frequently linked to chronic otitis or ear discharge.
• Temporal bone cancer can destroy bone, creating a pathway for infection to spread to the brain.

Observation:

• This paper details a rare case of brain abscess in a patient with concurrent temporal bone cancer.
• Fewer than four similar cases have been documented in medical literature.
• The observed patient presented with both a brain abscess and signs of infection/granulomatous mass in the ear.

Findings:

• The study highlights the unusual co-occurrence of otogenic brain abscess and temporal bone malignancy.
• Temporal bone cancer can serve as a critical route for central nervous system infection.
• Diagnostic challenges exist in differentiating infectious from malignant processes in the ear.

Implications:

• Biopsy is recommended for otogenic brain abscesses with coexisting ear infection and granulomatous mass to exclude malignancy.
• Early detection of underlying malignancy is crucial for effective treatment of brain abscess in such complex cases.
• This case underscores the importance of considering rare etiologies in complex neurological presentations originating from the ear.
