Brain Abscess of Dental Origin: A Case Report and Literature Review

Introduction: Brain abscess (BA)of dental origin is a rare but potentially life-threatening complication of odontogenic infection that requires immediate neurosurgical attention. It is defined as an encapsulated collection of pus in various areas of the brain. The infectious process spreads from the dental site and occurs in 2 ways: haematogenous route or by contiguity. Treatment should ideally be based on the etiological factor excision, combined with drainage and adjuvant antibiotic therapy. The aim of this article was to report a case of frontal brain abscess of dental origin and to review the literature. Case report: We present the case of a 36-year-old man diagnosed with a brain abscess located in the frontal lobe and caused by a periodontal lesion of the right upper first molar. The final diagnosis was established due to the availability of computed tomography and magnetic resonance imaging. Drainage of the pus combined with extraction of the tooth and antibiotic therapy was followed by an excellent recovery. Clinical and radiological features, treatment and follow-up data were documented. A review of the literature using the PubMed database was performed Conclusion: Oral infections can lead to life-threatening infections, such as brain abscesses. Early detection of this condition through correct diagnosis is essential to give the patient the best treatment; in addition, improving of the oral environment and treating oral infections is highly recommended to limit this serious condition.
