An Unusual Etiology of Lemierre-Like Syndrome: Preseptal Cellulitis due to Methicillin-Resistant Staphylococcus aureus

Lemierre’s syndrome (LS) is a rare and potentially fatal condition that predominantly affects young adults with oropharyngeal infection. Fusobacterium necrophorum is the usual etiology and classically causes internal jugular vein septic thrombophlebitis, frequently complicated by septic emboli to several organs (most classically to the lungs). Lemierre-like syndrome (LLS) describes the same constellation of symptoms and pathophysiology as Lemierre’s syndrome; however, Fusobacterium spp. are not the cause and the source of infection may be non-oropharyngeal. We present a case with an unusual etiology of LLS: a patient with untreated preseptal cellulitis and associated methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in the setting of injection drug use. Physical exam revealed tachypnea and rhonchi with severe periorbital and bilateral eyelid edema. Imaging demonstrated bilateral preseptal and orbital cellulitis with thrombosis of both internal jugular veins and bilateral pulmonary cavitary lesions consistent with septic pulmonary emboli. She was managed with anticoagulation and parenteral antibiotics. To our knowledge, this is the first case of LLS originating from preseptal cellulitis without evidence of preceding pharyngitis. While facial and orbital infections are rare etiologies of LLS, the potentially devastating sequelae of LLS warrants its inclusion in differential diagnoses.
