Otogenic brain abscess, precipitated by acute mastoiditis, is a rare but potentially fatal condition. It constitutes an intracranial complication that can further develop due to meningitis and sigmoid sinus thrombosis. This case underscores the critical importance of early detection and therapeutic intervention, which often pose substantial clinical challenges. This report elucidates the case of a 35-year-old female who arrived with severe otalgia, noted predominantly on the right side, coupled with discharge and vertigo. Subsequent neuroimaging unveiled the presence of basal meningitis in the right cerebellar hemisphere, accompanied by an extradural abscess and coalescent mastoid air cells. The patient's treatment protocol entailed a rigorous antibiotic regimen, continually adjusted based on symptomatic improvement. The rapid diagnosis and immediate treatment of otogenic brain abscesses are paramount. As observed in our case, factors such as limited medical knowledge, oversight in medical care, and socio-economic disadvantages contributed to the severity of the intracranial complication. These elements highlight the necessity of addressing systemic factors in healthcare to ensure effective prevention and management of such conditions.
