A unique case of Lemierre’s syndrome status post blunt cervical trauma

Abstract

Background: Lemierre’s syndrome is a rare but potentially fatal condition. The course is characterized by acute tonsillopharyngitis, bacteremia, internal jugular vein thrombosis, and septic embolization. There have been some cases secondary to penetrating trauma to the neck. Literature review has yielded no cases secondary to blunt neck trauma in the absence of oropharyngeal injury. We aim to shed light on this unique cause of Lemierre’s syndrome, so as to raise the index of suspicion for clinicians working up patients with blunt cervical trauma. Methods: We present a case of a 25-year-old male restrained driver who presented with left neck and shoulder pain with a superficial abrasion to the left neck from the seatbelt who was discharged same day by the Emergency Room physicians. He returned to the Emergency Department two days later with abdominal pain. As a part of his repeat evaluation, a set of blood cultures were sent and was sent home that day. The patient was called back to the hospital one day later as preliminary blood cultures were positive for Gram positive cocci and Gram negative anaerobes. Computerized tomography scan of the neck revealed extensive occlusive left internal jugular vein thrombosis and fluid collections concerning for abscesses, concerning for septic thrombophlebitis. The patient continued to decompensate, developing severe sepsis complicated by disseminated intravascular coagulation. Results: The patient underwent a left neck exploration with en bloc resection of the left internal jugular vein, drainage of abscesses deep to the sternocleidomastoid, and washout/debridement of necrotic tissue. Direct laryngoscopy at the time of surgery revealed no injury to the aerodigestive tract. Wound cultures were consistent with blood cultures and grew Fusobacterium necrophorum, Staphylococcus epidermidis, and Methicillin-resistant staphylococcus aureus. The patient underwent two subsequent operative wound explorations without any evidence of residual infection. The patient was discharged home on postoperative day 13 on a course of antibiotics and aspirin. Conclusion: This case illustrates the importance of diagnosis of Lemierre’s syndrome after an unconventional inciting event (blunt cervical trauma) and appropriate treatment.
