Severe atypical Lemierre syndrome caused by methicillin-sensitive Staphylococcus aureus: Two pediatric case reports.

BACKGROUND:Lemierre syndrome is typically associated with ear, nose, and throat (ENT) infections caused by Fusobacterium necrophorum. Since 2002, cases of atypical Lemierre-like syndrome secondary to Staphylococcus aureus have been reported. CASES:We report two pediatric cases of atypical Lemierre syndrome with a similar presentation: exophthalmia, absence of pharyngitis, metastatic lung infection, and intracranial venous sinus thrombosis. Both patients had a favorable outcome following treatment with antibiotics, anticoagulation, and corticosteroids. CONCLUSION:Regular therapeutic monitoring of antibiotic levels helped to optimize antimicrobial treatment in both cases.
