A Lemierre's like syndrome in a 50 days old infant with Enterobacter cloaca bacteremia: A case report.

Lemierre syndrome describes septic thrombophlebitis of the internal jugular vein (IJV) and metastatic spread of the infection following a recent oropharyngeal infection in a setting of bacteremia caused by Fusobacterium necrophorum. Lemierre-like syndrome describes similar clinical scenario with no preceding oropharyngeal infection and/or in the setting of non-Fusobacterium cause. We report a case of Lemierre-like syndrome in a setting of Enterobacter cloaca bacteremia without known preceding oropharyngeal infection. History and physical exam revealed an irritable infant with cough, tachypnea, low grade fever, bilateral lung crepitations and features of infantile seborrheic dermatitis on the scalp. Imaging revealed thrombosis of right internal jugular vein and superior vena cava, bilateral pulmonary cavitary lesions and collections consistent with septic pulmonary emboli. Multiple rim enhancing hypo-dense liver lesions and chest wall collections consistent with abscesses were also seen. He was managed with parental antibiotics, drainage of the chest wall abscesses and discharged with clinical and radiologic improvement.

Lemierre's syndrome associated-diabetic ketoacidosis in an elderly female: a case report.

BACKGROUND: The co-occurrence of Lemierre's syndrome, primarily triggered by Fusobacterium necrophorum following oropharyngeal infection, with diabetic ketoacidosis (DKA) in diabetes mellitus (DM) patients, underscores a rare but life-threatening clinical scenario. Lemierre's syndrome induced DKA is extremely rare, with only one case report in adult and no case yet reported in elderly. CASE PRESENTATION: We reported a case of a 69-year-old female who presented with DKA triggered by deep neck space infection (DNSI), leading to rapid clinical deterioration within 6 h that necessitated high flow nasal cannula (HFNC) and antibiotic administration. Laboratory findings included leukocytosis, elevated serum C-reactive protein, hyperglycemia, ketonemia, and severe metabolic acidosis. Culture of the fluid from a neck mass puncture drainage and blood were positive for Klebsiella pneumoniae. The patient was further complicated by thrombosis of the left internal jugular vein with extension to the sigmoid and a neck abscess surrounding the carotid artery sheath, consistent with Lemierre's syndrome. This condition was managed aggressively with fluid resuscitation, insulin therapy, surgical drainage, antibiotics, and anticoagulation led to a significant improvement in her condition. Following a 13-day hospitalization, there was significant clinical improvement, culminating in the patient's discharge. CONCLUSIONS: The case highlights the need for greater awareness and understanding of the interrelated and mutually promoting conditions of DKA and Lemierre's syndrome among clinicians. Early recognition and treatment are crucial to prevent mortality in such complex cases.

Lemierre Syndrome in the Setting of Bacteremia and Atypical Pneumonia: A Case Report.

Lemierre syndrome is an uncommon condition that typically presents with oropharyngeal infection and subsequent thrombophlebitis of the internal jugular veins. The syndrome is associated with septic emboli, frequently of the lungs, as well as Fusobacterium necrophorum bacteremia. Here, we report a case of Lemierre syndrome in the setting of an atypical pulmonary pathology. During the patient's clinical course, a peritonsillar abscess was identified, as well as associated septic emboli and superimposed Mycoplasma pneumoniae in the setting of F. necrophorum bacteremia. Prompt imaging and antibiotic treatment, in addition to an incision and drainage of the peritonsillar abscess, allowed for the patient to be medically optimized for discharge home with intravenous and oral antibiotics. Early recognition of this rare syndrome can help guide treatment and promote positive outcomes for patients affected by Lemierre syndrome.

There is no well-being without oral health: a case report of Lemierre's syndrome due to neglected odontogenic infection.

Lemierre's syndrome is marked by presence of septic thrombophlebitis in the internal jugular vein. This case report describes a 57-year-old woman who presented with a progressively swelling neck with onset 1 day prior to admission. She had a history of untreated dental infection. Physical examination revealed slightly increased blood pressure, at 140/80 mmHg, and a painful, erythematous, warm swelling in the mid area of the neck. Ultrasound of the neck revealed occlusive intraluminal thrombus in the right internal jugular vein, a computed tomography (CT) scan with contrast showed that there was a blockage in the right jugular vein. The mainstay treatment for Lemierre's syndrome is antibiotics, while administration of anticoagulants remains controversial. The patient was treated conservatively, with administration of antibiotics and anticoagulant. Several days later the patient's condition had improved significantly, with less pain and reduced swelling.

A síndrome de Lemierre é caracterizada pela presença de tromboflebite séptica da veia jugular interna. Este relato de caso descreve uma mulher de 57 anos que apresentou edema progressivo no pescoço 1 dia antes da internação. Ela tinha histórico de infecção dentária não tratada. O exame físico revelou pressão arterial levemente aumentada (140/80 mmHg), além de protuberância dolorosa, eritematosa e com aumento da temperatura na região média do pescoço. A ultrassonografia do pescoço revelou trombo intraluminal na veia jugular interna direita, e a tomografia computadorizada com contraste mostrou que havia trombose na veia jugular direita. O tratamento principal da síndrome de Lemierre é a antibioticoterapia, enquanto a administração de anticoagulantes permanece controversa. A paciente foi tratada de forma conservadora com administração de antibióticos e anticoagulantes. Vários dias depois, a condição da paciente melhorou significativamente, com diminuição do nível de dor e do tamanho da protuberância.

Infectious Thrombophlebitis of the Left Internal Jugular Vein With Tissierella praeacuta Isolation in a 71-Year-Old Female: A Case Report.

Tissierella praeacuta, a rare pathogen, was found in a 71-year-old female's internal jugular vein thrombus stemming from sphenoid sinusitis. She presented with lower-extremity weakness, and imaging revealed the thrombus. Subsequent intraoperative cultures identified T. praeacuta. Treatment encompassed intravenous antibiotics and anticoagulation. This case underscores the need to consider unusual pathogens in sinusitis-related thrombosis. To the authors' knowledge, this report is the first documented case of T. praeacuta isolated in sinusitis leading to infectious thrombophlebitis, and it adds to the scarce literature on T. praeacuta infections, emphasizing a multidisciplinary approach for such complex cases.

Facial vein thrombophlebitis post facial skin infection: a case report and review of the literature.

This case report presents a rare instance of facial vein thrombophlebitis, a potentially serious complication, following a facial skin infection. A 33-year-old man known to have cerebral palsy, epilepsy on ventriculoparietal shunt, and kyphoscoliosis presented to the emergency department complaining of small facial wound and swelling for 1 week. The wound failed topical management and fever started to develop. His medications included quetiapine and levetiracetam. Investigations, including computed tomography, were carried out to rule out an extension to deep tissue. Management in the emergency department involved initial resuscitation with 500 mL of 0.9% normal saline and 1 L of lactated ringers, antibiotic coverage with piperacillin/tazobactam and vancomycin was given, and analgesia for pain control. This case highlights the potential for facial vein thrombophlebitis as a complication of facial skin infections. Early diagnosis and prompt initiation of appropriate management are crucial to prevent potentially fatal consequences.

[Sore throat with septic complications]. / Halsschmerzen mit septischen Komplikationen.

A young man presented with exertional dyspnea and thoracic pain following pharyngitis. The findings included pulmonary melting, left-sided pleural empyema and spondylitis. Cultures for detection of the pathogen were negative and sequencing for bacterial DNA was additionally carried out resulting in detection of Fusobacterium necrophorum that is typical for oropharyngeal infections. Furthermore, environmental diagnostics revealed two infected molars as a possible source of the infection and a jugular vein thrombosis. The results were compatible with Lemierre syndrome. This case highlights the potential of molecular diagnostics of pathogens.

Case Report: An Unusual Case of Lemierre's Syndrome Presenting as Influenza B-Induced Myositis Complicated by Streptococcus intermedius Infection.

Lemierre's syndrome (LS) is a rare and severe complication primarily associated with the bacteria Fusobacterium necrophorum and characterized by an oropharyngeal infection leading to bacteremia and septic thrombophlebitis. We present a case of an 89-year-old patient with a history of hypertension who initially presented with type B influenza infection and neck pain. She subsequently developed a neck abscess with thrombosis of the internal jugular vein. We believe this to be the first reported case in the literature of LS secondary to Streptococcus intermedius presenting after infection with type B influenza. As more atypical LS cases emerge, it is becoming increasingly clear that this condition can manifest in a number of ways. This unique case highlights the importance of considering LS as a differential diagnosis for patients of all ages presenting with neck pain and Streptococcus intermedius infection.

Lemierre's syndrome presenting with arterial and Central nervous system involvement.

A 17-year-old male presented with acute onset right-sided facial swelling, trismus, pharyngitis, and sepsis. An initial CT abdomen and pelvis revealed multifocal bilateral nodular cavitary lung lesions. CT soft tissue neck with contrast demonstrated a parapharyngeal abscess and thrombophlebitis of the right internal jugular vein. The patient was subsequently diagnosed with Lemierre's syndrome. On the following day, the patient's neurological status markedly declined. Brain MRI/MRA/MRV showed right internal carotid artery narrowing, multiple areas of acute and subacute infarctions secondary to vasculitis, meningitis, venous sinus thrombosis, and intracerebral abscesses. Workup for primary causes of intracranial vasculitis was negative. Although commonly presented as venous disease, this case highlights a rare presentation of Lemierre's syndrome with arterial involvement and significant intracranial complications. Clinicians should consider vasculitis and central nervous system involvement as potential complications of Lemierre's syndrome rather than searching for separate aetiologies.

Collateral pathways arising from internal jugular venous occlusion in Lemierre's syndrome.

The use of anticoagulants in Lemierre's syndrome is not well-defined, lacking clear evidence for their efficacy. This report describes a patient with complete occlusion of the internal jugular vein by a thrombus who did not develop expected complications due to the formation of collateral venous channels.

Endogenous endophthalmitis secondary to Lemierre's Syndrome originating from pharyngotonsillitis.

PURPOSE: The purpose of this article is to report a case of Lemierre's Syndrome producing unilateral endogenous endophthalmitis in a healthy, young woman with a history of tonsillitis. CASE REPORT/OBSERVATIONS: A 17-year-old healthy woman developed fever after a few days of sore throat. She later developed pneumonia with septic signs, leading to admission to the Intensive Care Unit. Lemierre Syndrome was diagnosed due to multiple septic pulmonary emboli and signs of sepsis following a recent episode of tonsillitis. During hospitalization, the patient complained of decreased visual acuity and floaters in her left eye. Ophthalmological examination revealed papillary edema, vitritis, foci of chorioretinitis in the macula and Roth's spots, confirming the diagnosis of endogenous endophthalmitis. Subsequently, she underwent appropriate treatment, progressing satisfactorily. CONCLUSION AND IMPORTANCE: Although ophthalmological manifestations are rare, due to the pathophysiological characteristics of Lemierre's Syndrome, all patients should underwent standard ophthalmologic assessment, even in the absence of ophthalmic symptoms or visible findings, as part of a multidisciplinary management approach.

Lemierre's Syndrome: A Case Report of Thrombophlebitis of the Internal Jugular Vein Induced by Laryngeal Cancer.

Lemierre's syndrome, a rare complication of oropharyngeal infections, is characterized by septic thrombophlebitis primarily affecting the internal jugular vein, which can lead to septicemia, thrombotic obstruction, and potential dissemination to distant sites. We present the case of a 54-year-old male with a history of chronic smoking and newly diagnosed laryngeal carcinoma, complicated by Lemierre's syndrome. Initial symptoms included odynophagia, dyspnea, and cervical swelling, with subsequent diagnosis confirming thrombosis of the internal jugular vein via ultrasound, CT, and MRI. Treatment included broad-spectrum antibiotics and anticoagulation, followed by oncological management for the carcinoma. This case underscores the diagnostic challenge posed by concurrent malignancy and highlights the critical role of early recognition and comprehensive treatment involving antibiotics, anticoagulation, and oncological therapy. Multidisciplinary collaboration is crucial for optimizing outcomes in complex cases like this, emphasizing the need for heightened clinical suspicion and prompt intervention involving proper imaging diagnosis, appropriate antibiotic coverage, and timely microbiological recognition for adjustment of antimicrobial therapy.

Association of pathogenic determinants of Fusobacterium necrophorum with bacteremia, and Lemierre's syndrome.

Fusobacterium necrophorum is a Gram-negative anaerobic bacterium responsible for localized infections of the oropharynx that can evolve into bacteremia and/or septic thrombophlebitis of the jugular vein or peritonsillar vein, called Lemierre's syndrome. To identify microbial genetic determinants associated with the severity of this life-threatening disease, 70 F. necrophorum strains were collected and grouped into two categories according to the clinical presentation: (i) localized infection, (ii) bacteremia with/without Lemierre's syndrome. Comparative genomic analyses revealed two clades with distinct genetic content, one clade being significantly enriched with isolates from subjects with bacteremia. To identify genetic determinants contributing to F. necrophorum pathogenicity, genomic islands and virulence factor orthogroups (OVFs) were predicted. The presence/absence profiles of OVFs did not group isolates according to their clinical category, but rather according to their phylogeny. However, a variant of lktA, a key virulence factor, with a frameshift deletion that results in two open reading frames, was associated with bacteremia. Moreover, a genome-wide association study identified three orthogroups associated with bacteremic strains: (i) cas8a1, (ii) a sodium/solute symporter, and (iii) a POP1 domain-containing protein. Further studies must be performed to assess the functional impact of lktA mutation and of these orthogroups on the physiopathological mechanisms of F. necrophorum infections.

Case report: The use of metagenomic next-generation sequencing to diagnose Lemierre's syndrome caused by lost root canal fillings in a 33-year-old patient with metabolic syndrome.

Background: Lemierre's syndrome is a rare and serious complication of pharyngitis with an estimated annual incidence of 1 in 100,000 people worldwide. It is characterized by septic thrombophlebitis of the internal jugular vein with metastatic infection, usually after oropharyngeal infection. Rare cases of Lemierre's syndrome have been reported to be caused by odontogenic infection. Case report: A 33-year-old male visited our hospital with symptoms of fever and sore throat for 16 days. The other symptoms included pain in his left neck and shoulder. In addition, metabolic syndrome was diagnosed based on waist circumference, diabetes, and hyperlipidemia. Fusobacterium necrophorum bacteria was detected using the metagenomic next-generation sequencing (mNGS) technique. The enhanced computerized tomography (CT) scan showed thrombosis of the left proximal jugular vein and brachiocephalic vein. Based on these observations, Lemierre's syndrome was diagnosed. The etiology was that the fillings in the root canal tooth were lost with no blood or pain about 2 weeks before the onset. The patient recovered after treatment with antibiotics and blood purification. Conclusion: Lemierre's syndrome should be evaluated for patients with fever, sore throat, and neck pain. If the loss of fillings from root canal therapy occurs, especially for those with metabolic syndrome, we should be aware of the possibility of this disease. Furthermore, the mNGS test can be used as a crucial supplementary diagnostic tool for patients with undetermined fever.

A rare case of MRSA associated Lemierre's syndrome.

Lemierre's syndrome, or postanginal sepsis, is an uncommon but potentially fatal infection of the internal jugular vein. The combination of bacteremia, internal jugular vein thrombophlebitis, and metastatic septic emboli secondary to acute pharyngeal infections is characteristic of Lemierre's syndrome. Isolated pathogens are typically oral anaerobic bacteria, most commonly Fusobacterium necrophorum. While the incidence of Lemierre's syndrome has declined over the years, the proportion of cases caused by uncommonly implicated bacteria have been increasingly cited in the literature (1). In this case report, we introduce a novel presentation of Lemierre's syndrome in a patient who presented to the emergency department with neck swelling and shortness of breath and was found to have infectious myositis and bacteremia with methicillin-resistant Staphylococcus aureus. Clinicians should be vigilant of underlying thrombus in patients with neck swelling and infectious myositis as our patient's internal jugular vein thrombus was missed on initial computed tomography read.

Epstein-Barr virus as promoter of Lemierre syndrome: systematic literature review.

PURPOSE: To investigate a possible link between acute Epstein-Barr virus infection and Lemierre syndrome, a rare yet life-threatening infection. METHODS: A systematic review was conducted adhering to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Diagnosis criteria for Lemierre syndrome were established, and data extraction encompassed demographic data, clinical, and laboratory information. RESULTS: Out of 985 initially identified papers, 132 articles were selected for the final analysis. They reported on 151 cases of Lemierre syndrome (76 female and 75 male patients with a median of 18 years) alongside interpretable results for Epstein-Barr virus serology. Among these, 38 cases (25%) tested positive for acute Epstein-Barr virus serology. There were no differences in terms of age, sex, or Fusobacterium presence between the serologically positive and negative groups. Conversely, instances of cervical thrombophlebitis and pulmonary complications were significantly higher (P = 0.0001) among those testing negative. The disease course was lethal in one case for each of the two groups. CONCLUSIONS: This analysis provides evidence of an association between acute Epstein-Barr virus infection and Lemierre syndrome. Raising awareness of this link within the medical community is desirable.

A Rare and Dangerous Combination of COVID-19, Lemierre Syndrome, and Carotid Pseudoaneurysm: A Case Report.

Lemierre syndrome is a rare complication of oropharyngeal infection that causes septic thrombophlebitis in the internal jugular vein. Since the onset of the COVID-19 pandemic, this condition has been dangerously overlooked and poses an even greater threat when complicated by vascular pathologies. A case is presented where the patient required emergency endovascular exclusion of a right internal carotid artery pseudoaneurysm due to Lemierre syndrome. The treatment included stent graft placement and drainage of a neck abscess, along with appropriate antibiotic treatment during hospitalization. Recognizing this diagnosis requires a high index of suspicion, particularly during the COVID-19 pandemic. The complexity of the disease necessitates extensive multidisciplinary collaboration for effective treatment.

Lemierre's Syndrome with a Palmar Lesion.

Lemierre's syndrome can be fatal if diagnosed late or not treated appropriately. We herein report a 40-year-old woman with a fever and pain with tenderness in her palms after the administration of antibiotics for pharyngotonsillitis. She was diagnosed with Lemierre's syndrome, and her symptoms improved after the administration of intravenous ampicillin-sulbactam. In this case, the palmar lesions indicated septic emboli and were an important finding in recognizing Lemierre's syndrome. Lemierre's syndrome should be considered in the differential diagnosis of patients with a persistent fever following oropharyngeal infection, even if they have received antimicrobial therapy, resolved pharyngeal symptoms, and negative culture results.

Lemierre's syndrome complicating multiple organ failure caused by Fusobacterium necrophorum subsp. funduliforme F1260: Case report and review.

We described a case of a 24-year-old man with multiple organ failure caused by Fusobacterium necrophorum subsp. funduliforme F1260. This is the first described case of Lemierre's syndrome with multiple organ failure due to F. necrophorum subsp. funduliforme F1260 in an adult in China. Our study highlights that there may be a risk of misdiagnosis based solely on typical manifestations of internal jugular vein thrombophlebitis, metastatic lesions, and F. necrophorum isolated from blood cultures or normally sterile sites. Clinicians should be cognizant of the potential utility of metagenomic next-generation sequencing in facilitating early pathogen detection in severe infections, thus enabling timely and appropriate administration of antibiotics to reduce mortality rates and improve prognosis.
