Background: Lemierre syndrome is a rare but potentially life-threatening condition characterized by septic thrombophlebitis of the internal jugular vein, most commonly caused by Fusobacterium necrophorum.
Case Presentation: A 46-year-old woman with no significant medical history presented with generalized neck swelling and fever. Despite seeking medical attention at multiple outpatient clinics for upper respiratory symptoms lasting 10 days, she only received symptomatic treatment for acute viral pharyngitis. A computed tomography (CT) scan of her neck revealed thrombophlebitis in the left internal jugular vein, and subsequent cultures indicated the presence of Klebsiella pneumoniae. The patient's oxygen saturation levels suddenly dropped, and the CT scan identified bilateral peripheral consolidation areas in both lungs, consistent with septic emboli. These findings were consistent with a diagnosis of Lemierre syndrome. The patient was treated with 2 weeks of intravenous piperacillin/tazobactam and vancomycin, as well as anticoagulation therapy using heparin, and her symptoms resolved completely.
Conclusion: This report presents an unusual occurrence of Lemierre syndrome caused by K. pneumoniae, a less frequently encountered causative pathogen in patients without diabetes mellitus. The case highlights the significance of timely and appropriate antibiotic use to prevent potential complications.

Article Synopsis
- Lemierre's syndrome is a rare, potentially life-threatening condition that can be caused by various bacteria, not just those initially identified by Andre Lemierre.
- A 62-year-old male patient with type 2 diabetes presented with severe neck swelling and required extensive medical interventions due to complications such as pulmonary abscesses and septic shock.
- Successful treatment involved the antibiotic meropenem and improved glycemic control, leading to the patient's recovery and discharge, underscoring the need for clinicians to be aware of diverse pathogens associated with Lemierre's syndrome, especially in diabetic patients.

We describe a case of orbital cellulitis with abscess formation following eyebrow piercing complicated by internal jugular vein thrombosis and subretinal abscesses requiring enucleation with orbital abscess drainage. The popularity of body piercing is increasing and physicians should be familiar with the possibility and management of vision-threatening complications of facial piercing. Following left eyebrow piercing, a 20-year-old female experienced increasing periorbital swelling, erythema, chemosis, orbital pain, decreased vision, and concomitant fever, chills, and rhinorrhea.

Background: Fusobacterium species are anaerobic Gram-negative bacilli which are uncommon causes of bloodstream infection (BSI). This genus commonly colonises the gastrointestinal tract and can result in significant morbidity.
Methods: All blood cultures with growth of Fusobacterium species among residents of Queensland, Australia (population ≈ 5 million) were retrospectively identified over a 20-year period.

Introduction: Fusobacterium necrophorum is a rare but significant cause of septic arthritis, typically following oropharyngeal infections in adolescents. This anaerobic pathogen, commonly associated with Lemierre's syndrome, can lead to joint infections, posing risks for severe morbidity if diagnosis and treatment are delayed. Awareness and timely intervention are essential for preventing long-term joint damage.
