Lemierre's syndrome: more than a historical curiosa

A 36-Year-Old Male With Left-Sided Neck Pain and Progressive Dyspnea

CASE PRESENTATION

A 36-year-old male with no significant medical history presented to the ED with progressive left-sided neck and facial pain for the last 7 days. The patient also reported subjective fevers, chills, difficulty opening his mouth, and anorexia for the last 1 week. He denied cough, chest pain or tightness, shortness of breath, skin rashes, dysphagia, or odynophagia. He reported use of two to three 59.15 mL beers daily for the last 20 years. There was no recent travel or sick contact exposure. He did not report any TB exposure, IV drug use, or recent sexual encounters.

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

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.

Case Report on Mycobacterium tuberculosis Presenting As Lemierre's Syndrome: A Reemerging Catastrophe

Lemierre's syndrome is characterized by internal jugular vein thrombophlebitis and bacteremia, primarily from anaerobic organisms. The condition usually arises after a recent oropharyngeal infection. Young, healthy people with prolonged pharyngitis that progresses into septicemia, pneumonia, or lateral neck stiffness should be suspected of having Lemierre's syndrome. Identifying internal jugular vein thrombophlebitis and developing anaerobic bacterial growth on blood culture are frequently used to confirm the diagnosis. Treatment consists of long-term antibiotic treatment, sometimes in conjunction with anticoagulant medication. In this case report, we describe the unique case of a 29-year-old male with Mycobacterium tuberculosis with pulmonary tuberculosis, tubercular meningitis, tuberculosis-related acute ischemic stroke with septic thrombophlebitis. The patient presented with sudden onset altered sensorium for 4 hours. Magnetic resonance imaging of the brain was done, which suggested obstructive hydrocephalus with periventricular ooze. The patient was started on antibacillary treatment, antibiotics, anticoagulants, and systemic steroids. The patient was vitally stable when he was discharged. Therefore, it is crucial to consider the likelihood of such atypical tuberculosis presentations while providing a prompt and relevant diagnosis and recommending the right course of therapy.

Lemierre syndrome: a diagnostic dilemma of critical care in the post-COVID era

Lemierre syndrome (LS) is referred to as the 'forgotten Disease' owing to its rarity in the postantibiotic era with an estimated yearly incidence of 1/million population. The classic triad of LS includes internal jugular vein thrombosis, oropharyngeal infection and metastatic septic emboli. We present a case of typical LS with Fusobacterium and Prevotella infection, presenting with peritonsillar abscess and jugular vein thrombosis complicated by sepsis, acute hypoxic respiratory failure due to multiple pulmonary emboli and severe thrombocytopaenia in the absence of disseminated intravascular coagulation.

Lemierre syndrome causing empyema and pulmonary embolism: A reemerging disease from a bygone era?

Long considered a "forgotten disease" of a bygone era, the apparent reemergence of Lemierre syndrome highlights the need for awareness of this rare condition to ensure timely diagnosis and treatment. Lemierre syndrome should be suspected in young adults presenting with a chest or neck infection and requires prolonged antibiotic therapy, surgical drainage of collections, and often anticoagulation.

A man with culture sterile cavitating lung lesions: molecular techniques can provide the key to diagnosis

A 20-year-old male presented to the Emergency Department with pyrexia, dyspnoea, chest pain and haemoptysis. Cavitating lung lesions were noted on chest X-ray and the patient was admitted to the intensive care unit where he was intubated and ventilated. Routine investigations including serial cultures did not provide an aetiological diagnosis. As such, a CT-guided lung biopsy was carried out and 16S rDNA PCR was undertaken on the sample. This identified Fusobacterium necrophorum as the causative organism. The patient was treated for Lemierre's syndrome and successfully discharged from hospital. This case highlights how DNA tissue typing on a lung biopsy sample can be the key to successful diagnosis in an atypical pneumonia and raises the question as to whether this infrequently used approach should be added to forthcoming community acquired pneumonia guidelines.

Lemierre's Syndrome Caused by Klebsiella pneumoniae: A Case Report and Literature Review

Lemierre's syndrome is a rare condition that involves anaerobic sepsis following pharyngitis and is characterized by a high mortality rate. It often manifests as a septic embolism within the internal jugular vein due to oropharyngeal infections, leading to vein wall inflammation. Despite modern antibiotics, Lemierre's syndrome remains underdiagnosed and poses a significant threat. We report the case of a 43-year-old man who has alcoholic liver cirrhosis and diabetes mellitus. Symptoms included chest pain, back pain, and neck swelling, with Klebsiella pneumoniae leading to the diagnosis of K. pneumoniae-associated Lemierre's syndrome. Furthermore, K. pneumoniae-associated Lemierre's syndrome is linked to diabetes mellitus and the elderly population. Notably, it showed a tendency for distant metastases, particularly in the lungs and brain. Additionally, central nervous system and renal involvement were observed in a smaller subset of cases.

Lemierre's Syndrome in the 21st Century: A Literature Review

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 Due to Streptococcus anginosus: A Case Report and Review of the Literature

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 Associated With Papillary Thyroid Cancer and Cerebellar Stroke

A 53-year-old woman with no past medical history presented to the Emergency Department with right frontal headache and ipsilateral neck pain. She was found to have right internal jugular vein thrombosis, right cerebellar stroke, meningitis, septic pulmonary emboli, and fusobacterium bacteremia, all consistent with a severe presentation of Lemierre's syndrome (LS). While LS is often preceded by nasopharyngeal infection, no such history was elicited from our patient. Instead, concomitant papillary thyroid cancer with extension to her right internal jugular vein was implicated. Prompt recognition of these multiple related processes led to a timely initiation of appropriate therapy for infection, stroke, and malignancy.

Lemierre's Syndrome (LS) Complicated by Cranial Nerve XII Palsy

Lemierre's syndrome (LS) is a rare medical condition that involves an acute oropharyngeal infection leading to septic thrombophlebitis of the internal jugular vein with embolic spread to organs like the kidneys, lungs, and large joints. Only very little literature has reported central nervous system involvement with LS. This is a case of 34-year-old woman with right-sided neck pain, swallowing difficulties, and a sore throat of 3 days duration at the time of presentation. CT of the neck with contrast showed a ruptured right peritonsillar abscess and thrombus in the right internal jugular vein suspicious of thrombophlebitis. The patient was managed for LS with IV antibiotics and anticoagulation. However, her clinical course was complicated by cranial nerve XII palsy, which is an extremely rare manifestation of LS.

Severe atypical Lemierre syndrome caused by methicillin-sensitive Staphylococcus aureus: Two pediatric case reports

BACKGROUND

Lemierre syndrome is typically associated with ear, nose, and throat (ENT) infections caused by Fusobacterium necrophorum. Since 2002, cases of atypical Lemierre-like syndrome secondary to Staphylococcus aureus have been reported.

CASES

We report two pediatric cases of atypical Lemierre syndrome with a similar presentation: exophthalmia, absence of pharyngitis, metastatic lung infection, and intracranial venous sinus thrombosis. Both patients had a favorable outcome following treatment with antibiotics, anticoagulation, and corticosteroids.

CONCLUSION

Regular therapeutic monitoring of antibiotic levels helped to optimize antimicrobial treatment in both cases.

Monkeypox presenting as supraglottitis in an immunocompromised patient

We describe a young man with AIDS who presented to the ear, nose and throat team with a severe sore throat mimicking supraglottitis. He had a 3-day history of sore throat, hoarse voice, fevers and myalgia. On examination, he had cervical lymphadenopathy and profuse pus overlying his right tonsil. On flexible nasoendoscopy, this pus was seen to track down to the supraglottis, with associated mucosal ulceration. The patient was treated for supraglottitis and he improved. 24 hours postadmission, a pustule suspicious for monkeypox developed on the patient's hand. The diagnosis was confirmed by PCR testing. The patient was isolated and treated supportively and recovered fully. This case highlights that monkeypox may present with a severe sore throat without cutaneous lesions. Monkeypox is a growing public health concern . Its early symptoms are non-specific and healthcare professionals should be alert to it.

Forget-me-not: Lemierre's syndrome, a case report

Background: Familiarity breeds complacency. One case of sore throat can start to sound like another. However, even common viral and bacterial infections can lead to serious sequelae. Clinicians cannot make a diagnosis if they do not consider it in their differential.Case: The presentation - and subsequent hospitalization - of a septic 19 year-old male college student is described. Despite brief interval improvement, he became hypoxic one week after developing a sore throat and was ultimately diagnosed with Lemierre's syndrome (septic thrombophlebitis of the internal jugular vein) via blood cultures and advanced imaging.Conclusions: Though rare, Lemierre's syndrome carries a high mortality rate. It should be considered an emergent complication of head and neck infections, particularly in young adults.

Lemierre's Syndrome in the External Jugular Vein Precipitated by COVID-19 Infection

Lemierre's syndrome is a condition when an oropharyngeal infection, typically from Fusobacterium necrophorum, causes thrombophlebitis of the internal jugular vein. There have been few case reports of Lemierre's syndrome affecting the external jugular vein, but to our knowledge, this is the first case report where COVID-19 infection is the prime suspect for causing this syndrome. SARS-CoV-2 infection, known to cause hypercoagulability and immunosuppression, increases the risk of deep venous thrombosis and secondary infections. We report a case of a young male with no known risk factors who developed Lemierre's syndrome as a complication of COVID infection.

Comparative Genomic Analysis of Fusobacterium necrophorum Provides Insights into Conserved Virulence Genes

Fusobacterium necrophorum is a Gram-negative, filamentous anaerobe prevalent in the mucosal flora of animals and humans. It causes necrotic infections in cattle, resulting in a substantial economic impact on the cattle industry. Although infection severity and management differ within F. necrophorum species, little is known about F. necrophorum speciation and the genetic virulence determinants between strains. To characterize the clinical isolates, we performed whole-genome sequencing of four bovine isolates (8L1, 212, B17, and SM1216) and one human isolate (MK12). To determine the phylogenetic relationship and evolution pattern and investigate the presence of antimicrobial resistance genes (ARGs) and potential virulence genes of F. necrophorum, we also performed comparative genomics with publicly available Fusobacterium genomes. Using up-to-date bacterial core gene (UBCG) set analysis, we uncovered distinct Fusobacterium species and F. necrophorum subspecies clades. Pangenome analyses revealed a high level of diversity among Fusobacterium strains down to species levels. The output also identified 14 and 26 genes specific to F. necrophorum subsp. necrophorum and F. necrophorum subsp. funduliforme, respectively, which could be essential for bacterial survival under different environmental conditions. ClonalFrameML-based recombination analysis suggested that extensive recombination among accessory genes led to species divergence. Furthermore, the only strain of F. necrophorum with ARGs was F. necrophorum subsp. funduliforme B35, with acquired macrolide and tetracycline resistance genes. Our custom search revealed common virulence genes, including toxins, adhesion proteins, outer membrane proteins, cell envelope, type IV secretion system, ABC (ATP-binding cassette) transporters, and transporter proteins. A focused study on these genes could help identify major virulence genes and inform effective vaccination strategies against fusobacterial infections. IMPORTANCE Fusobacterium necrophorum is an anaerobic bacterium that causes liver abscesses in cattle with an annual incidence rate of 10% to 20%, resulting in a substantial economic impact on the cattle industry. The lack of definite biochemical tests makes it difficult to distinguish F. necrophorum subspecies phenotypically, where genomic characterization plays a significant role. However, due to the lack of a good reference genome for comparison, F. necrophorum subspecies-level identification represents a significant challenge. To overcome this challenge, we used comparative genomics to validate clinical test strains for subspecies-level identification. The findings of our study help predict specific clades of previously uncharacterized strains of F. necrophorum. Our study identifies both general and subspecies-specific virulence genes through a custom search-based analysis. The virulence genes identified in this study can be the focus of future studies aimed at evaluating their potential as vaccine targets to prevent fusobacterial infections in cattle.

Lemierre's Syndrome: A Lethal Complication of Acute Tonsillitis

Tonsillitis is a condition involving the infection of the lymphoid tissue of the tonsils. This pathology of the tonsils is frequently reported as a childhood illness in children of school-going age. The leading causative agent which is associated with tonsillitis is Group A and B Haemolytic Streptococcus and Staphylococcus and Haemophilus influenzae. With rapid and correct treatment and management with antibiotics and analgesics, it can be resolved, and the patient can be free of the symptoms such as sore throat, dysphagia, pain over the throat, and fever. Though in the minority of cases the diseases can progress and can result in multiple complications which sometimes can be lethal and extremely serious. These can be rheumatic fever, acute glomerulonephritis, or tonsillar cyst. One of the sporadic but equally important and grave syndromes is Lemierre's syndrome, which unfortunately has been labelled as a forgotten disease due to the development of antibiotic therapy and management of the disease. The mortality of the disease was extremely high in the pre-antibiotic era. This disease presents the following findings, such as thrombophlebitis of the internal jugular vein, which usually occurs after the presentation of pharyngeal infection. Which in later stages also gives rise to thrombi that advance and extend throughout the body, in the form of septic emboli. The important microorganism which is isolated and associated with the Lemierre's is Fusobacterium necrophorum, a strict gram-negative anaerobe. This article emphasizes and discusses the pathophysiology, and microbiology of Lemierre's syndrome. It also focuses on the clinical symptoms that include the appropriate and timely diagnosis and treatment of this deadly and fatal syndrome, together with the complications that arise with Lemierre's syndrome as the presenting problem.

Lemierre's syndrome with cranial epidural abscess complication: A case report

Introduction

Lemierre's syndrome is a rare disease typically manifested by thrombophlebitis of the jugular vein and septic embolism following a history of oropharyngeal infection. Fusobacterium necrophorum is the causative agent of Lemierre syndrome, commonly known as post-anginal sepsis.

Case presentation

We reported a 24-year-old male who came to the emergency department complaining of a history of a sore throat, fever, malaise, fever, and neck swelling with a normal consciousness level. A laboratory examination showed leukocytosis and high C-reactive protein serum. Radiological diagnosis reveals an anterior neck abscess with left jugular vein thrombosis and left epidural abscess. The blood culture was positive for Fusobacterium necrophorum. The patient underwent surgical drainage and, at the same time, was treated with antibiotics and anticoagulant drugs. After 45 days, the patient improved clinically and was discharged. There were no other symptoms after a one-month follow-up clinically and neck ultrasonography.

Clinical discussion

Lemierre's syndrome has historically had a high mortality rate, approximately up to 90% before antibiotics. The disease's incidence has declined gradually, leading it to become recognized as the “forgotten disease.” Nevertheless, the incidence of Lemierre syndrome has been increasing over the last twenty to thirty years. Primary oropharyngeal infection, bacteremia, radiographic or clinical evidence of internal jugular vein thrombosis, and septic metastatic foci are the main clinical hallmarks of Lemierre's syndrome. Surgical debridement, antibiotics, and anticoagulants are the treatments of choice.

Conclusion

Lemierre's syndrome with cranial epidural abscess is very rare. It is a forgotten disease. Nowadays, the prevalence is increasing. Awareness of clinical and radiological features will aid the prompt management of patients.

•

Lemierre's syndrome with cranial epidural abscess is a rare disease that mostly affects young adults and is commonly caused by Fusobacterium necrophorum.

•

A clinical manifestation characterized by jugular vein thrombosis and septic embolism following a history of oropharyngeal infection.

•

It is a forgotten disease. Nowadays, the prevalence is increasing. Awareness of clinical and radiological features will aid the prompt management of patients.

Atypical presentation of Lemierre syndrome in a young healthy man with acute jaundice

This report presents a case of Lemierre syndrome caused by Fusobacterium necrophorum in a healthy young adult who presented atypically with shortness of breath and jaundice but no clinical or diagnostic evidence of thrombophlebitis. Due to this unusual presentation with jaundice, diagnosis was challenging and delayed. However, the patient was successfully initiated on a prolonged course of intravenous antibiotics; he required a period in the intensive care unit and was discharged without significant complications. This report aims to raise awareness of the diagnosis and treatment of this rare condition and to highlight both common and unusual presentations of the syndrome.

Lemierre’s Syndrome as a Sexually Transmitted Disease Due to Porphyromonas asaccharolytica Suspected to Be Caused by Pharyngitis Due to Mycoplasma pneumoniae and Epstein-Barr Virus

Porphyromonas asaccharolytica rarely causes Lemierre's syndrome (LS), which is characterised by sepsis and thrombophlebitis of the internal jugular vein.

An 18-year-old man presented with fever and a sore throat after sexual contact containing oral sex, and his blood sample was positive for atypical lymphocytes. Infectious mononucleosis was suspected initially. However, laboratory data showed elevated D-dimer and procalcitonin levels, and a computed tomography scan showed a thrombus in the internal jugular vein leading to the diagnosis of LS. The Mycoplasma pneumoniae (MP) IgM titre was 1:640 (normal, ≦1:40), and the Epstein-Barr nuclear antigen titre (taken 59 days after admission) was 1:10 (normal, <1:10). It was assumed that LS developed after infection with Epstein-Barr virus (EBV) and MP.

LS should be suspected in young patients with fever and sore throat with a history of recent sexual contact. As pharyngitis was considered the cause of LS, evaluation of the preceding infection such as MP or EBV leading to pharyngitis should also be considered.

A common complaint… a rare disease!

A 2-year-old previously well child presented to the emergency department with temperatures and lethargy. He was pale and looked unwell. He received a fluid bolus and was commenced on intravenous ceftriaxone. Pus was discharging from his left ear with postauricular swelling and erythema. Given clinical concerns, urgent neuroimaging was arranged.

Case report of Lemierre's Syndrome associated with Fusobacterium nucleatum infection without internal or external jugular venous thrombophlebitis

Fusobacterium nucleatum is an anaerobe that is commensal to the human oral cavity. It is usually a component of periodontal plaque that is emerging as a pathogen and quickly attracting attention of the medical and research communities. It has been even discovered in bronchoalveolar lavage of some patients with lung cancer. Lemierre's syndrome (LS) is characterized as septic thrombophlebitis of the internal jugular vein, which usually begins with oropharyngeal infection that worsens and leads to inflammation of the wall of the jugular vein. This is the hallmark of the disease. However, in this case, there was no thrombophlebitis of the internal jugular vein. There is one other case presentation where it was diagnosed without the internal jugular vein involvement. Most sequelae involve infected thrombus of the vein, soft tissue inflammation, persistent bacteremia, and septic emboli, often leading to metastatic infections. Interestingly enough, in the age of SARS-COV-2, LS has also been mistaken for multisystem inflammatory syndrome in children (MIS-C).

We present a previously healthy 20-year-old female college student who was transferred from her local hospital to Bristol-Myers Squibb Children's Hospital (BMSCH) at Robert Wood Johnson University Hospital for suspected LS with loculated pleural effusions and necrotizing pneumonia with lung abscess secondary to Fusobacterium nucleatum, systemic and emphysematous osteomyelitis possibly secondary to septic emboli, thrombocytopenia, and palatine tonsil and thyroid abscesses.

Pylephlebitis Caused by Fusobacterium nucleatum in a Septuagenarian Healthy Caucasian Male: Atypical Presentation of Lemierre’s Syndrome

Lemierre's syndrome (LS) is characterized by thrombophlebitis of the internal jugular vein caused primarily by Fusobacterium necrophorum. LS is usually suspected in fit young adults with prolonged or prior pharyngeal infection. Atypical Lemierre's syndrome is commonly defined as Fusobacterium-associated thrombophlebitis outside the head-neck veins and usually occurs in older patients than typical Lemierre's syndrome. Here we present a case of atypical LS in a septuagenarian healthy Caucasian male with no prior history of pharyngitis and in whom both computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated partial portal vein thrombosis associated with Fusobacterium nucleatum. This case report confirms previous reports of Fusobacterium nucleatum-associated LS variants presenting with abdominal vein thrombosis and illustrates clinical recovery after a combination of anticoagulation and antibiotic therapy.

Paralysis: A Rare Presentation of Lemierre's Syndrome: A Case Report

CASE

A patient presented with acute paralysis in the setting of undiagnosed Lemierre's syndrome. Streptococcus pyogenes was the causative organism leading to internal jugular vein thrombosis, sternocleidomastoid abscess, vertebral osteomyelitis, and epidural phlegmon. The patient was treated both surgically, with abscess evacuation, hemicorpectomy, and fusion, and medically, with antibiotics and anticoagulation. Postoperatively, the patient regained upper extremity strength and lower extremity sensation, but the paraplegia remained.

CONCLUSION

Lemierre's syndrome is a rare complication of oropharyngeal infection with a constellation of findings including jugular thrombophlebitis, metastatic abscesses, and frequent involvement of anaerobic pathogens that may present acutely with paralysis.

Early Diagnosis and Antibiotic Treatment Combined with Multicomponent Hemodynamic Support for Addressing a Severe Case of Lemierre's Syndrome

A 20-year-old man was admitted to the intensive care unit for septic shock due to Lemierre’s syndrome. It is a rare syndrome that manifests as an upper respiratory infection, although systemic involvement, severe coagulopathy, and multi-organ failure can dangerously complicate the clinical picture. In this syndrome, sepsis-related neuroendocrine dysregulation and microcirculation impairment can have a rapid deleterious progression. Consequently, proper diagnosis, early source control, and appropriate antibiotics administration are mandatory to improve the prognosis. The intensive treatment is aimed at limiting organ damage through hemodynamic optimization. Remarkably, in septic shock due to Lemierre’s syndrome, hemodynamic optimization can be achieved through the synergic effect of norepinephrine, argipressin, and hydrocortisone.

Lemierre's Syndrome: A Case Series

Lemierre’s syndrome (LS) is a potentially fatal complication of oropharyngeal infection, resulting in contiguous suppurative thrombosis of the internal jugular vein (IJV) and septic emboli. It is most commonly associated with Fusobacterium necrophorum (F. necrophorum), though other pathogens have also been implicated in its pathogenesis. The incidence of LS had so significantly decreased that it was referred to as "the forgotten disease." However, cases of LS have shown a resurgence, which may be partly attributed to an overreliance on a negative group A beta-hemolytic streptococcal rapid antigen detection test (RADT), commonly referred to as "rapid strep test." Clinicians must maintain a very high index of suspicion for LS in patients with persistent sequelae from tonsillopharyngitis who have a negative RADT.

A Case of Embolic Spread of Fusobacterium necrophorum From Presumed Pharyngitis

Fusobacterium necrophorum is the most common pathogen isolated in individuals diagnosed with the rare and life-threatening illness known as Lemierre's syndrome. Lemierre's syndrome commonly involves a triad of infection in the oropharyngeal region, thrombophlebitis of the internal jugular vein, and distant metastases of said infection. Our case involves an embolic spread of F. necrophorum to the lungs, which was presumed to have originated in the pharynx, in the absence of internal jugular vein thrombosis. The clinical course of the patient was further complicated by an initial diagnosis of community-acquired pneumonia, severe sepsis, and disseminated intravascular coagulation. After suitable input from the multi-disciplinary team and adequate antibiotic therapy, the patient demonstrated a positive outcome with complete recovery to her baseline.

Severe case of Lemierre syndrome with multiple neurological and ophthalmological sequelae

A 56-year-old man was admitted to intensive care with septic shock, multiple facial abscesses and thrombophlebitis of the right internal jugular vein with extensive intracranial extension. A diagnosis of Lemierre syndrome due to Streptococcus anginosus was made and treatment initiated with high-dose ceftriaxone and metronidazole, along with surgical debridement. His admission was complicated by raised intraocular pressures and visual loss requiring bilateral canthotomies. Despite therapeutic anticoagulation with enoxaparin, he also developed an ischaemic basal ganglia infarct. After a prolonged and complex hospital stay, the patient was later readmitted with an intracerebral abscess requiring surgical excision and a second course of antibiotics. This case highlights the value of early recognition of this rare but potentially life-threatening condition, considerations around anticoagulation and antibiotic decisions, and the importance of close multidisciplinary follow-up even after discharge from hospital.

Lemierre's syndrome associated with hypervirulent Klebsiella pneumoniae: A case report and genomic characterization of the isolate

We describe a case of Lemierre’s syndrome (LS) caused by a hypervirulent strain of Klebsiella pneumoniae in a 63-year-old female with hypertension, hyperlipidemia, and diabetes mellitus, who presented with right neck pain and fevers. Computerized tomography of the neck and chest revealed an occluded right internal jugular vein secondary to thrombosis and septic emboli in lungs. Blood cultures grew K. pneumoniae. The patient was treated with ampicillin-sulbactam and then transitioned to amoxicillin-clavulanate to complete a 6-week course of antibiotics, and a 3-month course of rivaroxaban. String test of the K. pneumoniae isolate was positive at 2 cm. Whole genome sequencing identified several genes associated with the hypervirulent strain, notably the genes encoding for aerobactin (iucA and iucB) and salmochelin (iroB) iron acquisition systems. LS can rarely be caused by K. pneumoniae. Clinicians should monitor for known complications, such as septic emboli in patients with LS.

Lemierre's syndrome

Lemierre's syndrome is a rare and potentially life-threatening condition that follows an oropharyngeal infection, typically from Fusobacterium necrophorum, and usually affects healthy adolescents or young adults. The characteristic features are septic thrombophlebitis of the internal jugular vein and septic embolism leading to multiorgan involvement, commonly the brain, lungs and bones. We report a man with presenting symptoms suggesting hemicrania continua, whose initial imaging showed no features of dural venous sinus or jugular thrombosis. Two weeks later, he had fever, sore throat, cervical lymphadenopathy and Actinomyces meyeri grew from peripheral blood cultures. Further imaging identified thrombosis of the internal jugular vein and cerebral venous sinuses, with multifocal cavitating lung lesions. Following antibiotics and anticoagulation, he recovered without residual deficits. Lemierre's syndrome when recognised and treated early has a good prognosis but delayed treatment may result in significant morbidity or mortality.

Lemierre's Syndrome: A Case Report

Lemierre’s syndrome is a condition in which an oropharyngeal infection progresses to sepsis and thrombophlebitis of the internal jugular vein. Although the incidence of this syndrome has fallen dramatically since the widespread use of antibiotic therapy to treat streptococcal pharyngitis, it should still be suspected in otherwise healthy young patients presenting with the triad of prolonged pharyngitis, lateral neck pain, and septic symptoms. In this report, we explore a unique case of Lemierre’s syndrome complicated by hypercoagulability and ineffective initial antibiotic therapy.

Lemierre's syndrome with cavernous sinus thrombosis caused by dental infection

Lemierre's syndrome is a rare multisystemic infection beginning in oropharynx commonly caused by oral anaerobic organisms and leading to internal jugular vein thrombosis with septic emboli. Here, we describe a 45-year-old woman with hypertension and unrecognised type 2 diabetes who presented to a community hospital with fever, double vision and septic shock. Examination showed neck pain aggravated by neck flexion, limited ocular movement of right lateral rectus, left medial rectus and left superior oblique and incomplete ptosis of the left eye. These symptoms were suggestive of bilateral cavernous sinus syndrome. CT of the brain showed bilateral proximal internal jugular vein and cavernous sinus thrombosis. CT angiography revealed septic emboli at both upper lungs. The patient had good improvement of neurological symptoms after dental extraction, intravenous antibiotic and anticoagulant.

Lemierre Syndrome: Unusual Presentation With Superior Ophthalmic Vein Thrombosis

ABSTRACT

Lemierre syndrome (LS) is a rare, but serious condition most commonly associated with oropharyngeal bacterial infection. Infection results in thrombophlebitis of the internal jugular vein and its tributaries. It usually affects previously healthy young adults. The authors report an unusual case of an elderly patient with penicillin allergy who developed Lemierre syndrome from an odontogenic infection (Streptococcus intermedius) resistant to clindamycin. She developed thrombosis of the internal jugular vein and superior ophthalmic vein resulting in visual changes. Treatment required incision and drainage, intravenous antibiotics and anticoagulation. Antibiotics were tailored to culture and sensitivities after testing response to a beta-lactam. With antibiotic resistance increasing, investigation of penicillin allergies is warranted for severe head and neck infections.

Infectious Brachial Plexopathy and Septic Arthritis of the Shoulder due to Lemierre's Syndrome: A Case Report and Literature Review

CASE

We present a 20-year-old female with Lemierre's syndrome and an associated infectious brachial plexopathy and missed septic shoulder arthritis. She subsequently presented with advanced post-infectious glenohumeral joint arthritis. At the final 12-month follow-up, substantial shoulder pain and dysfunction persisted.

CONCLUSIONS

When Lemierre's syndrome has been diagnosed, patients with upper extremity symptoms suggestive of metastatic infection require a thorough assessment to rule out musculoskeletal involvement and site-specific intervention to prevent long-term morbidity.

A teenager with fever, chest pain, and respiratory distress during the coronavirus disease 2019 pandemic: a lesson on anchoring bias

Symptoms of coronavirus disease 2019 overlap with other important illnesses affecting young adults. We report a case of a 17-year old male presenting to the emergency department in the midst of a pandemic with symptoms of coronavirus disease 2019. He had fever, dyspnea, chest pain, and myalgias, with bilateral infiltrates on chest radiograph, and developed septic shock secondary to infectious thromboembolic events. However, his blood cultures grew group G streptococcus secondary to his oropharyngeal infection, and he experienced an infectious thrombus in the internal jugular vein, consistent with the rare but well-described Lemierre's syndrome. This case report calls attention to the importance of maintaining differential diagnoses and thereby minimizing the biases and assumptions that come with clinical care during a pandemic.

Lemierre's syndrome: a forgotten life-threatening entity

Lemierre's syndrome is a very rare but potentially fatal condition. It mainly affects adolescents and young adult males, and usually arises as a serious complication of pharyngitis or peritonsillar abscess. It is characterised by the triad of internal jugular vein septic thrombophlebitis, septic emboli (mostly pulmonary) and the isolation of the agent 'Fusobacterium necrophorum' in sterile fluids. In this report, it is described a case in which the nonspecific and subtle clinic made the diagnosis difficult to reach. In fact, only the dissociation between flu-like symptoms and the presence of significant changes in the blood tests (suggestive of acute bacterial infection), led to the request for imaging tests, which proved to be essential for the final diagnosis and subsequent control of the disease. This case report aims to increase the awareness among Ear, Nose and Throat (ENT) residents, paediatricians and family doctors about the existence of this entity and its potential life-threatening nature.

Late presentation of 'Lemierre's syndrome': how a delay in seeking healthcare and reduced access to routine services resulted in widely disseminated Fusobacterium necrophorum infection during the global COVID-19 pandemic

The SARS-CoV-2 outbreak has disrupted the delivery of routine healthcare services on a global scale. With many regions suspending the provision of non-essential healthcare services, there is a risk that patients with common treatable illnesses do not receive prompt treatment, leading to more serious and complex presentations at a later date. Lemierre’s syndrome is a potentially life-threatening and under-recognised sequela of an oropharyngeal or dental infection. It is characterised by septic embolisation of the gram-negative bacillus Fusobacterium necrophorum to a variety of different organs, most commonly to the lungs. Thrombophlebitis of the internal jugular vein is frequently identified. We describe an atypical case of Lemierre’s syndrome involving the brain, liver and lungs following a dental infection in a young male who delayed seeking dental or medical attention due to a lack of routine services and concerns about the SARS-CoV-2 outbreak.

Lemierre's syndrome in the pediatric population: Trends in disease presentation and management in literature

OBJECTIVE

This study aims to examine literature on Lemierre's Syndrome (LS) in the pediatric population over time in order to describe patterns in disease progression, management, and prognosis. In addition, this study assesses specific rate of literature output and the location of research over the past 10 years.

METHODS

A literature review was conducted through two databases, PubMed.gov and PMC. A search was conducted using the keywords "Lemierre syndrome" and "postanginal sepsis." Literature was primarily reviewed for demographic, radiographic, and clinical data. Articles were included in the study if they were published in English and within the last 10 years. All types of research studies were recorded, however primary data collection came from case reports and series. Publications were grouped into two time periods: 2009-2013 and 2014-2019, allowing for comparison of various characteristics between these two groups.

RESULTS

A total of 124 research studies on LS met inclusion criteria and were reviewed. Of these, 98 case reports (79.0%) were examined. Disease Characteristics: Fusobacterium necrophorum was the most common precipitating pathogen isolated from cultures (66.2%). The main primary treatment modalities used were antimicrobials, surgery, anticoagulation, or a combination of these treatments. A total of 63.9% of the case reports indicated use of anticoagulation at some point during treatment. Publication Trends: The number of published studies has not significantly changed in the last decade, with a non-statistically significant decline of 5.6%, when comparing 2014-2019 to 2009-2013 (p = 0.21). Case reports/series were the most common study design (82.2% vs 69.5%) and level of evidence for published studies continued to be stable (level 4-5) through the years (86.9%). The number of publications within an international journal vs US based journal has also remained steady during both time periods (p = 0.698).

CONCLUSION

LS is an uncommon condition but one that is important for physicians to be aware of in the pediatric population. Treatment regimens including antibiotics and anticoagulation have remained stable through the past 10 years, however the efficacy of anticoagulation in treating LS continues to be debated. Though LS is considered a severe illness with potentially life threatening complications, publications on this topic, in pediatrics specifically, have decreased within the past five years.

A Systematic Review of Lemierre's Syndrome With a Focus on Ophthalmologic Complications

Lemierre's syndrome (LS), once known as "the forgotten disease," is a rare and potentially life-threatening condition that has had a gain in incidence over the last 30 years due to a variety of factors that could include changes in antibody prescription patterns, particularly in regard to the treatment of pharyngitis/tonsillitis. Due to its low incidence and broad spectrum of symptoms, LS does not have an obvious clinical diagnosis and can confuse the clinician managing the patient. Furthermore, it is equally difficult to treat patients suffering from LS as it requires a multidisciplinary approach from multiple subspecialties. Thus, communication between hospitalists, radiologists, otolaryngologists, neurologists, and ophthalmologists is critical towards quickly diagnosing the disease condition so that prompt antibiotics, anticoagulation, and surgical intervention can occur. Atypical presentations can also exist, making the diagnosis and management exponentially more challenging. Ophthalmologic symptoms are a particularly rare and atypical presentation of LS. These rare symptoms in LS can be terrifying for patients and providers alike; yet, there does not seem to be any modern medical literature that summarizes ophthalmologic complications for LS patients. To our knowledge, this is the first systematic review of LS with a focus on ophthalmologic complications that has been done. The main objective of this review paper is to provide an up-to-date literature review of LS epidemiology, pathophysiology, diagnosis, and treatment while also performing a novel systematic review of reported cases of LS with ophthalmological complications. We hope to bring more awareness towards LS and its atypical presentations so that physicians will be better able to rapidly diagnose and treat their patients in order to minimize long-term morbidity and mortality.

Lemierre's syndrome in an intravenous drug user

A 29-year-old Dominican man with a history of intravenous heroin use and hepatitis C presented with a 5-day history of fever, dyspnoea, haemoptysis, pleuritic chest pain, abdominal pain, haematochezia and haematemesis. Initial physical examination was significant for scleral icterus, generalised abdominal tenderness to palpation, melaena and blood-tinged sputum. Blood cultures grew Fusobacterium species. CT scan of the chest revealed multiple bilateral cavitary features in lung fields. At the same time, a neck ultrasound performed demonstrated thrombophlebitis in the right internal jugular vein, confirming the diagnosis of 'Lemierre's syndrome'. Treatment was with antibiotics and supportive care for 6 weeks.

[Cervicofacial cellulitis complicated by internal jugular vein thrombosis]

INTRODUCTION

Cervicofacial cellulitis (CFC) is one of the most common dermatological infectious emergencies, and related morbidity and mortality are non-negligible.

PATIENTS AND METHODS

We describe the case of a 31-year-old male with left parotitis complicated by CFC with worsening over the previous week despite treatment with clindamycin and non-steroidal anti-inflammatory drugs. A cervicofacial computed tomography (CT) scan showed left internal jugular vein thrombosis (IJVT). Chest imaging showed no pleuropulmonary lesion, and bacteriological samples were negative. The patient received broad-spectrum antibiotic therapy and anticoagulants for 6 weeks. The outcome was quickly favourable.

DISCUSSION

It is essential to perform a cervicofacial contrast-enhanced CT scan for any CFC to map the affected areas, detect the primary infection and screen for loco-regional complications such as IVJT. The occurrence of IJVT in an infectious setting should prompt screening for septic emboli, especially pulmonary emboli, as well as performance of a chest CT scan. The presence of septic emboli associated with a recent ENT infection and of IJVT or Fusobacteriumnecrophorum in blood cultures are indicative of Lemierre's syndrome.

CONCLUSION

IJVT is an uncommon complication of CFC that occurs either alone or as part of Lemierre's syndrome.

A 4-year-old boy with Lemierre's syndrome caused by methicillin-sensitive Staphylococcus aureus

A pre-school aged boy presented to the Pediatric Emergency Department with a high grade fever and neck pain and stiffness. Blood culture was positive for methicillin-sensitive Staphylococcus aureus (MSSA) and Doppler ultrasound of the neck revealed partial thrombosis of the left internal jugular vein. He was diagnosed with Lemierre's syndrome (LS) and treated with a prolonged course of antibiotics and anticoagulation. After discharge home, he was followed in the outpatient clinics and had a full recovery. This case report will highlight the presentation of LS and will briefly review the microbiology of this condition.

A Rare Case of Lemierre's Syndrome Caused by Streptococcus Intermedius, Presenting as an Epidural Abscess

Lemierre's syndrome is a rare but life-threatening condition characterized by an oropharyngeal infection typically secondary to Fusobacterium necrophorum resulting in septic thrombophlebitis of the internal jugular vein. Streptococcus intermedius is a particularly rare cause of Lemierre's syndrome with only a few cases reported in the literature. Here we describe a rare case of Lemierre's syndrome, caused by Streptococcus intermedius, likely secondary to an odontogenic infection, found to have a cervical epidural abscess with concomitant large retropharyngeal and prevertebral abscesses on presentation, in whom the clinical course was further complicated by an extensive cerebral venous sinus thrombosis. However, despite grave complications, early diagnosis and appropriate emergency management including intravenous antibiotics and surgical intervention led to a successful recovery, thus demonstrating that aggressive measures can potentially lead to a favorable outcome. 

The Forgotten Disease: A Case of Lemierre’s Syndrome with Distal Extremity Involvement

Once coined the “Forgotten Disease,” Lemierre's syndrome is a rare condition that results from oropharyngeal infection with the gram-negative, anaerobic Fusobacterium necrophorum. The typical progression of illness involves spread to adjacent structures such as the internal jugular vein with resulting thrombophlebitis. Septic emboli to distant sites are also a common sequela. Here, we present a case of Lemierre's syndrome in a 20-year-old, otherwise healthy, male. The patient presented with fever, sore throat, and dysphagia. Imaging revealed peritonsillar multiloculated fluid collections and necrotizing pneumonia with multiple pulmonary abscesses. The patient's hospital course was complicated by the development of necrotizing fasciitis in his right lower leg, which required incision and drainage with surgical washout. In addition to systemic intravenous antibiotics and anticoagulation, he underwent multiple thoracentesis procedures. The patient was ultimately transferred to a tertiary care center due to persistent fevers and lung abscesses. This case highlights the challenges of initial diagnosis, as well as the treatment choices faced by the attending physicians.

Lemierre's syndrome caused by Streptococcus pyogenes in an elderly woman

Lemierre's syndrome is characterized by septic thrombophlebitis of the internal jugular vein. It typically presents in healthy adolescents or young adults, usually preceded by an oropharyngeal infection, with the most common offending pathogen being Fusobacterium necrophorum. We present a case of Lemierre's syndrome in an elderly woman without antecedent oropharyngeal infection, caused by Streptococcus pyogenes. She was successfully treated with combined surgical and medical management.

Case of internal jugular vein thrombosis and fever: Lemierre's syndrome or Trousseau's syndrome?

Internal jugular vein thrombosis is a rare critical cardiovascular emergency, which has potential catastrophic clinical outcomes by resulting in stroke and pulmonary embolism. Several etiologies have been reported; however, there are limited data on Lemierre's and Trousseau's syndromes, which are both rare conditions with advanced disease progression and poor clinical outcomes. Lemierre's syndrome may present with typical progressively infectious symptoms and signs, including sore throat, neck mass, and fever, whereas Trousseau's syndrome may present with thrombophlebitis and painful edema. Without antibiotic agents controlling the infection, the condition of patients with Lemierre's syndrome may progress to sepsis or septic shock. The infection pattern plays an important role for differential diagnosis. Herein, we describe the case of a 46-year-old woman presenting with atypical symptoms of Trousseau's syndrome mimicking Lemierre's syndrome. Laboratory analysis including protein C, protein S, rheumatoid factor, and antinuclear antibody ruled out hypercoagulopathy and autoimmune vasculitis. Abdominal computed tomography and panendoscopy revealed ulcerative tumor at the antrum. Pathological examination confirmed the presence of signet-ring cell adenocarcinoma. We highlight the clinical features and etiologies of internal jugular vein thrombosis, especially in Lemierre's syndrome and Trousseau's syndrome, to aid physicians in making an early diagnosis and providing timely management.
