BACKGROUND: Lemierre\'s syndrome is a fatal and rare disease that is typically characterized by oropharyngeal infection and internal jugular vein thrombosis. Timely institution of appropriate antibiotics is the standard treatment.
METHODS: The authors report a case of Lemierre\'s syndrome. A 67-year-old male patient of Han ethnicity in China suffered from a large inflammatory neck mass involving left internal jugular vein thrombosis diagnosed as Lemierre\'s syndrome and finally cured by surgical treatment. In addition, a literature review was carried out through PubMed using the terms \"Lemierre\'s syndrome/disease and review, meta-analysis or retrospective study\" and \"Lemierre\'s syndrome/disease and internal jugular vein\". This search yielded six articles that recorded surgical methods such as drainage, craniotomy, tooth extraction, and ligation of the occluded vein to give clinicians more ideas about the treatment of the Lemierre\'s syndrome.
CONCLUSIONS: This is the first review to summarize the conditions under which surgical treatment are conducted. Additionally, this is the first report of such a large inflammatory neck mass that was completely cured by surgical resection and internal jugular vein ligation. The authors also offer several conclusions regarding surgical intervention in Lemierre\'s syndrome for the first time.

BACKGROUND: Lemierre syndrome is a rare, potentially fatal complication of oropharyngeal infections characterized by septic thrombophlebitis of the internal jugular vein. It primarily affects healthy adolescents and young adults. Its incidence declined after the antibiotic era, but it may have resurged in recent decades, likely due to judicious antibiotic use and increasing bacterial resistance. Prompt diagnosis and treatment are imperative to prevent significant morbidity and mortality.
METHODS: Lemierre syndrome has been called \"the forgotten disease,\" with a reported incidence of around 3.6 cases per million. The mean age at presentation is around 20 years old, though it can occur at any age. Lemierre Syndrome follows an oropharyngeal infection, most commonly pharyngitis, leading to septic thrombophlebitis of the internal jugular vein. F. necrophorum is the classic pathogen, though other organisms are being increasingly isolated. Metastatic infections, especially pulmonary, are common complications. Contrast-enhanced CT of the neck confirming internal jugular vein thrombosis is the gold standard for diagnosis. Long-course broad-spectrum IV antibiotics covering anaerobes are the mainstays of the disease\'s treatment. Anticoagulation may also be considered. Mortality rates are high without treatment, but most patients recover fully with appropriate therapy.
CONCLUSIONS: Lemierre syndrome should be suspected in patients with prolonged pharyngitis followed by unilateral neck swelling and fevers. Early diagnosis and prompt antibiotic therapy are key, given the potential for disastrous outcomes if untreated. An increased awareness of Lemierre syndrome facilitates its timely management.

Lemierre\'s syndrome, also known as anaerobic post-anginal septicemia, necrobacillosis, and the \"forgotten disease,\" is a rare manifestation. It is often presented with sepsis, sore throat, fever, neck pain, internal jugular vein thrombophlebitis/thrombosis, and septic emboli. The bacteria that are usually associated with the disease are Fusobacterium species, but it is also associated with Staphylococcus, Streptococcus, and other bacterial species. The diagnosis of Lemierre\'s syndrome is made based on evidence of septic thrombophlebitis, preceding oropharyngeal infection, and positive culture. Treatment usually consists of antibiotics directed toward the causative organism. The use of anticoagulation, although controversial, is shown to be beneficial by several studies. We describe a middle-aged patient who presented with a sore throat, neck pain, and dysphagia. Imaging of the neck and chest revealed right jugular thrombosis along with septic emboli in the lungs. The culture of the blood and pus drained from the peritonsillar abscess grew Streptococcus anginosus. In this study, we have illustrated the effective management of Lemierre\'s syndrome with antibiotics, anticoagulants, and needle aspiration of abscess.

Lemierre\'s syndrome is a rare, life-threatening complication of an acute oropharyngeal infection. It is generally characterised by pharyngitis secondary to Fusobacterium necrophorum, causing thrombophlebitis of the internal jugular vein and sepsis, with subsequent formation of septic emboli that can rapidly spread to different organ sites. The condition is associated with high mortality if treatment with antibiotics is delayed, and recent evidence suggests that patients are at significant risk of in-hospital morbidity and long-term neurological sequelae. Although it is agreed that antibiotics are the mainstay of treatment, there is currently no consensus on the use of anticoagulation in the condition. This review article aims to summarise our current understanding of Lemierre\'s syndrome with regard to its definition, epidemiology, microbiology, presentation, diagnosis, and treatment.

Lemierre\'s syndrome (LS) is a rare disease entity, which can be catastrophic if organism-directed treatment is not initiated early. Lemierre\'s syndrome is frequently caused by Fusobacterium infection which is frequently susceptible to clindamycin. Evidence suggests there is an increase in the incidence of cases of drug resistant Fusobacterium species. Through this case we present a unique case of a 45-year-old Caucasian female with Lemierre\'s Syndrome due to polymicrobial organisms that were resistant to clindamycin thus developing recurrent infections despite being on antibiotics.

Although Fusobacterium necrophorum is well described as an emerging pathogen of acute mastoiditis in young children, infection with other anaerobes can lead to similar severe sequelae including intracranial and extracranial suppurative thrombophlebitis and sepsis. We describe a patient whose unremarkable exposure history assumed increased significance upon obtaining the results of 16S next generation sequencing from a surgical specimen. The novel pathogen Bacteroides pyogenes is reviewed herein.

We report a case of a 17-year-old female who presented with orbital cellulitis and meningeal involvement secondary to severe paranasal sinusitis with positive blood culture for Fusobacterium necrophorum. The patient recovered after a 2-month course of systemic antibiotics and functional endoscopic sinus surgery.Fusobacterium necrophorum-induced orbital cellulitis is a rare entity, with only 5 previous cases reported in the literature, which are reviewed here as well. This review reveals that Fusobacterium necrophorum is an aggressive pathogen in orbital cellulitis and therefore we suggest that affected patients may require a correspondingly aggressive medical management. Furthermore, we advise additional workup to rule out Lemierre\'s syndrome, a severe complication of Fusobacterium necrophorum infection, including transthoracic echocardiogram, chest radiograph, upper extremities\' venous duplex and magnetic resonance venography.

Lemierre\'s syndrome (LS) is an uncommon clinical entity characterized by a primary oropharyngeal infection with subsequent septic thrombophlebitis. Diagnosis is made with clinical or radiographic evidence of internal jugular vein (IJV) thrombosis, along with metastatic focus such as lungs or joints. Life threatening thrombocytopenia in Lemierre\'s syndrome in the absence of disseminated intravascular coagulation (DIC) is rarely reported. We present a case of a 41-year-old woman with Lemierre\'s syndrome caused by beta-hemolytic group C streptococci and fusobacterium species manifested as worsening pharyngitis, IJV thrombosis, and complicated by severe thrombocytopenia.

BACKGROUND: Lemierre\'s syndrome is a rare and potentially fatal entity characterized by the spread of an oropharyngeal infection, with secondary suppurative thrombophlebitis of the internal jugular vein and septic emboli.
METHODS: We discuss the case of a 52-year-old male who developed Lemierre\'s syndrome following peritonsillar abscess. He presented with submandibular and submental swelling extending into the neck. His management included; incision and drainage of the abscesses; and prolonged anticoagulant therapy.
CONCLUSIONS: The incidence of Lemierre\'s disease appears to be increasing, perhaps due to ignorance of the disease by many clinicians, and diagnosis is often delayed with potentially fatal consequences.

Introduction: Lemierre\'s syndrome is a septic thromboembolic complication of an oropharyngeal or neck infection, primarily caused by Fusobacterium species. Although it usually affects young healthy patients, some case reports describe this syndrome in older population.Methods: A case report and a systematic review of the literature were conducted to investigate the late onset of Lemierre\'s syndrome. Forty-one articles were selected for the qualitative analysis, 39 for the quantitative analysis.Results: The average age of the study population was 52 years old. Diabetes mellitus and upper gastro-intestinal malignancy, common comorbidities in the study population, might play a role in the development of late-onset Lemierre\'s syndrome. Empiric antibiotic treatment should cover Fusobacterium and Streptococcus species both, which may cooperate to induce purulent disease. Reported unfavourable outcome was more than expected.Conclusion: Lemierre\'s syndrome in adulthood may differ from the usual version. This disease may further pass unrecognized, if presented out of the expected age range. Nevertheless, early diagnosis and prompt treatment are a requisite to prevent morbidity and mortality, which may be higher in this older population.
