Fulminant Multidrug-Resistant Streptococcus pneumoniae Meningoencephalitis After Elective ENT Surgery: A Case Report

Pneumococcal meningoencephalitis is a severe infection associated with high morbidity and mortality. Although typically community-acquired, postoperative cases following elective ENT surgery are exceedingly rare. Antimicrobial resistance (AMR) among Streptococcus pneumoniae further complicates management, and missed opportunities for vaccination represent preventable risks. We report a case of a 41-year-old man with multiple comorbidities who developed fulminant S. pneumoniae meningitis 48 h after septoturbinoplasty. The clinical course was atypical, with altered consciousness but no classical meningeal signs, necessitating urgent intubation and intensive care admission. Cerebrospinal fluid cultures identified an MDR pneumococcal strain resistant to penicillin and macrolides but susceptible to vancomycin and meropenem. Empirical therapy with vancomycin and meropenem, combined with adjunctive corticosteroids and multidisciplinary ICU care, led to complete neurological recovery. This case highlights a rare but life-threatening postoperative complication and underscores two critical lessons. First, the growing challenge of multidrug-resistant pneumococcus requires timely recognition, aggressive empiric therapy, and access to effective agents. Second, the absence of pneumococcal vaccination in this high-risk surgical patient illustrates a preventable gap in care. Integrating vaccination screening into preoperative evaluations may reduce the risk of catastrophic postoperative CNS infections.
