Purpose: To describe a patient with -associated Lemierre syndrome complicated by eventual cavernous sinus thrombosis (CST) that manifested as an isolated abducens nerve palsy.

Observations: A patient with a history of heavy alcohol use presented with Lemierre syndrome caused by an odontogenic infection due to . Despite initiation of intravenous antibiotics and eventual eradication of her bacteremia, she developed an isolated abducens nerve palsy on hospital day 7 due to associated CST.

Conclusions And Importance: CST is a rare complication of odontogenic infection and Lemierre syndrome. This case demonstrates the potential for primary odontogenic infections to progress to life- and sight-threatening diseases. This case also illustrates the importance of considering uncommon pathogens as the etiology of CST based on the suspected source of primary infection.

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.

Pott Puffy Tumor (PPT) is extremely rare, yet potentially severe condition characterized by osteomyelitis of the frontal bone associated with one or multiple subperiosteal abscesses, primarily from nasosinusitis. It is characterized by localized frontal swelling accompanied by a subperiosteal abscess. Clinicians and radiologists do not widely recognize this complication of frontal sinusitis and, hence it is likely to be overlooked in clinical practice.

Article Synopsis
  • * Initial treatments included antibiotics but follow-up revealed worsening symptoms and a diagnosis of empyema, which was linked to a bacterial infection from periodontal disease rather than standard sources.
  • * The case emphasizes the need to investigate rare pathogens in pleural infections, especially those that may originate from oral health issues, highlighting how complex these conditions can be in patients with multiple health concerns.
