Lemierre’s Syndrome Secondary to Shoulder Hematoma Complicated by COVID-19: A Case Report

Abstract

This case report illustrates a unique presentation of Lemierre’s syndrome precipitated by Fusobacterium necrophorum. This case report describes a 20-year-old patient who developed Lemierre’s syndrome secondary to a shoulder hematoma and neck abscess with multiple systemic complications in the absence of tonsillitis or oropharyngeal infection. Two weeks prior to presentation, the patient sustained a right shoulder injury and contracted COVID-19. Due to his Lemierre’s syndrome, he developed right internal jugular vein and subclavian vein thrombosis, septic lung emboli, right sided Horner’s syndrome, disseminated intravascular coagulation, pelvic collection, septic arthritis of pubic symphysis and osteomyelitis of the right pubic bone, and proximal left femoral shaft. The patient received non-operative and operative management to manage his Lemierre’s syndrome including surgical drainage, antibiotics, and anticoagulation; he was discharged following an extended hospital stay. This case report highlights a rare presentation of Lemierre’s syndrome secondary to a shoulder hematoma in a COVID-19 positive patient, and its potential systemic and life-threatening complications. Its importance is highly relevant in the context of the COVID-19 pandemic. Further studies are warranted to explore the effect of preceding COVID-19 infections on the microbiological profile in Lemierre’s syndrome.
