Endoscopic Endonasal Drainage of Cerebral Abscess: A Case Report and Revision of the Literature

Abstract

Brain abscess after rhinosinusitis is uncommon in clinical practice today, as a result of improvement in diagnosis as well as the increased use and efficacy of antibiotic treatment of rhinosinusitis. The role of expanded endoscopic endonasal approaches in treating skull base pathologies has significantly increased over the last decade, along with greater knowledge of the ventral anatomy of this region, offering a new method of brain abscess treatment. We present the case of a 24-year-old man with brain abscess secondary to acute sinusitis that was drained with an endoscopic endonasal approach. We discuss the pathogenesis, diagnosis, and appropriate treatment available in the literature.
