Surgical intervention of Lemierre's syndrome: a case report and review of the literature.

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. CASE PRESENTATION: 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. CONCLUSION: 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.

Atypical presentation of Lemierre's syndrome caused by penicillin-susceptible Staphylococcus aureus in a patient with chronic stomatitis and COVID-19.

A healthy man in his late 20s was admitted to the emergency department due to a flare-up in his severe chronic stomatitis, along with flu-like symptoms. CXR showed multiple bilateral consolidations and subsequent CT revealed thrombosis of the left facial and internal jugular vein, together with septic embolism in both lungs. Blood cultures showed penicillin-susceptible Staphylococcus aureus The patient was diagnosed with Lemierre's syndrome, despite atypical bacteria and clinical presentation. During hospitalisation, he developed pulmonary empyema as a complication and was admitted for 4 weeks. During hospitalisation and after discharge, the patient was examined for multiple rheumatic, immunological and dermatological diseases, but no underlying cause for Lemierre's syndrome has been found. We present this case due to the rarity of its nature, with atypical clinical presentation and pathogen for Lemierre's syndrome, but with classic radiological findings.

Delayed diagnosis of Lemierre's syndrome in a patient with severe coronavirus disease 2019: importance of comprehensive oral and neck examination - a case report.

BACKGROUND: Given the widespread prevalence of the coronavirus disease 2019 (COVID-19), oral and neck examinations tend to be avoided in patients with suspected or confirmed COVID-19. This might delay the diagnosis of conditions such as Lemierre's syndrome, which involves symptoms resembling COVID-19-related throat manifestations. CASE PRESENTATION: A 24-year-old man without any underlying conditions was diagnosed with COVID-19 7 days before presentation. He was admitted to another hospital 1 day before presentation with severe COVID-19 and suspected bacterial pneumonia; accordingly, he was started on treatment with remdesivir and meropenem. Owing to bacteremic complications, the patient was transferred to our hospital for intensive care. On the sixth day, the patient experienced hemoptysis; further, a computed tomography (CT) scan revealed new pulmonary artery pseudoaneurysms. Successful embolization was performed to achieve hemostasis. In blood cultures conducted at the previous hospital, Fusobacterium nucleatum was isolated, suggesting a cervical origin of the infection. A neck CT scan confirmed a peritonsillar abscess and left internal jugular vein thrombus; accordingly, he was diagnosed with Lemierre's syndrome. The treatment was switched to ampicillin/sulbactam, based on the drug susceptibility results. After 6 weeks of treatment, the patient completely recovered without complications. CONCLUSION: This case highlights the significance of thorough oral and neck examinations in patients with suspected or diagnosed COVID-19 for the detection of throat and neck symptoms caused by other conditions.

Septic thrombophlebitis of portal and splenic vein secondary to Fusobacterium nucleatum: A case report of an abdominal variant of lemierre syndrome.

RATIONALE: Septic thrombophlebitis of the internal jugular vein also known as Lemierre syndrome occurs secondary to an oropharyngeal infection often leading to septic embolisms to distant sites. Anaerobic gram-negative bacillus, Fusobacterium nucleatum and Fusobacterium necrophorum are commonly isolated organisms. Fusobacterium species has also been reported to complicate an intra-abdominal infection leading to septic thrombophlebitis of portal vein also known as pylephlebitis or abdominal variant of lemierre syndrome. PATIENT CONCERNS: The patient was a middle-aged female patient with chief complaints of abdominal discomfort, intermittent fever and vomiting for one month. DIAGNOSES: The final diagnosis was septic thrombophlebitis of portal and splenic vein secondary to Fusobacterium nucleatum. INTERVENTIONS: Patient was managed with broad spectrum intravenous antibiotics with coverage against gram-negative bacilli, anaerobes, and aerobic streptococcus species with therapeutic anticoagulation. OUTCOMES: Patient gradually improved and was discharged on oral apixaban. She was instructed to follow up with gastrointestinal specialist upon discharge in anticipation of the need for liver transplant in future. LESSONS: Due to its high mortality and associated long term disease morbidity, clinicians should always strive towards early diagnosis and treatment of the condition with involvement of multidisciplinary teams.

A case of Lemierre's syndrome causing panhypopituitarism, cavernous sinus thrombosis, ischaemic stroke and pulmonary embolism.

Infection is a rare cause of panhypopituitarism and has not been reported in the context of Lemierre's syndrome. We present the case of a previously well 19-year-old man, who presented acutely unwell with meningitis and sepsis. Fusobacterium necrophorum was isolated from peripheral blood cultures and identified on cerebrospinal fluid with 16S rDNA Polymerase Chain Reaction (PCR). Imaging demonstrated internal jugular vein thrombosis with subsequent cavernous venous sinus thrombosis. Pituitary function tests were suggestive of panhypopituitarism. The patient was diagnosed with Lemierre's syndrome complicated by meningitis, cavernous sinus thrombosis, base of skull osteomyelitis, ischaemic stroke and panhypopituitarism. He was treated with 13 weeks of intravenous antibiotics followed by 3 weeks of oral amoxicillin, and anticoagulated with dalteparin then apixaban. His panhypopituitarism was managed with hydrocortisone, levothyroxine and desmopressin.

Lemierre's syndrome-A diagnostic challenge.

In this case report, we present a young man with Lemierre's syndrome, which is a potentially fatal condition most commonly caused by the bacterium Fusobacterium necrophorum. When Lemierre's syndrome is suspected, it is important to consider X-ray, ultrasound, and CT scan, as they can bring tremendous diagnostic value.

[Anticoagulation in a patient with Lemierre syndrome and pulmonary septic embolisms]. / Anticoagulación en paciente con síndrome de Lemierre y embolias sépticas pulmonares.

Lemierre's syndrome, also called septic thrombophlebitis of the internal jugular vein, necrobacillosis or postanginal sepsis, is an infection that begins in the oropharyngeal space, is complicated by septic thrombophlebitis of the internal jugular vein and infectious metastases. The rapid progression to serious clinical conditions that compromise the patient's life and its low frequency justify the disclosure of clinical cases. We present the case of a 27-year-old woman who developed facial edema and trismus 48 hours after completing treatment with phenoxymethylpenicillin for an odontogenic infection. An angio-CT of the craniofacial massif revealed an extensive thrombus in the internal jugular vein and a computed tomography of the chest showed septic pulmonary emboli. Treatment consisted of broad-spectrum intravenous antibiotics and early anticoagulation.

El síndrome de Lemierre, también denominado tromboflebitis séptica de la vena yugular interna, necrobacilosis o sepsis postanginal es una infección que inicia en el espacio orofaríngeo, se complica con tromboflebitis séptica de la vena yugular interna y metástasis infecciosas. La rápida progresión a cuadros clínicos graves que comprometen la vida del paciente y su baja frecuencia justifican la divulgación de casos clínicos. Se presenta el caso de una mujer de 27 años de edad, que a las 48 horas de completar el tratamiento con fenoximetilpenicilina por una infección odontógena evolucionó con edema facial y trismus. En la angio-TC de macizo craneofacial se evidenció extenso trombo en la vena yugular interna y en la tomografía computarizada de tórax, embolias sépticas pulmonares. El tratamiento consistió en antibióticos endovenosos de amplio espectro y anticoagulación de manera precoz.

Complex Lemierre syndrome with multisystemic abscesses.

We present here the challenging case of severe Lemierre syndrome in a healthy woman in her late twenties, whose clinical presentation was characterised by lung abscesses and disseminated systemic abscesses in the brain, the abdomen and the soft-tissues, as a likely consequence of a patent foramen ovale. Blood cultures were positive for Fusobacterium necrophorum and a right lingual vein thrombosis was detected at a late stage when the patient developed a septic shock. Initial antimicrobial therapy with metronidazole and ceftriaxone was modified to meropenem due to progressive worsening. The patient underwent laparoscopy and neurosurgical drainage of a cerebral abscess. She spent many days in the intensive care unit and recovered fully after 6 weeks on meropenem therapy. Although considered rare, the incidence of Lemierre syndrome, a potentially life-threatening condition, is increasing. The clinician should promptly recognise and treat it while being aware of its potential atypical presentations.

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.

Elderly onset atypical Lemierre's syndrome concurrent with a rheumatoid vasculitis sacral ulcer infection: a case report.

BACKGROUND: Typical Lemierre's syndrome is usually secondary to an oropharyngeal infection. Recently, several cases following a primary infection site other than the oropharynx have been reported as atypical Lemierre's syndrome; although, these primary lesions are limited to the head and neck. This is the first case potentially sequential to infectious foci outside the head and neck. CASE PRESENTATION: We describe an atypical Lemierre's syndrome in a 72-year-old woman with rheumatoid arthritis, which occurred during the treatment of Streptococcus anginosus bacteremia acquired from a sacral ulcer infection related to rheumatoid vasculitis. At first, the symptoms resolved after the initial administration of vancomycin for the bacteremia caused by methicillin-resistant Staphylococcus aureus and Streptococcus anginosus that entered via a sacral ulcer. On the 8th day, the patient developed a fever of 40 °C and unexpectedly required 10 L of oxygen due to rapid deterioration of oxygenation temporarily. Immediately contrast-enhanced computed tomography was performed to investigate systemic thrombosis including pulmonary embolism. Afterward, the newly formed thrombi at the right external jugular vein, bilateral internal jugular veins, and the right small saphenous vein were detected, and apixaban was started. On the 9th day, the patient again had an intermittent fever of 39.7 °C, and continuous Streptococcus anginosus bacteremia was revealed; subsequently, clindamycin was administered. On the 10th day, she developed a left hemothorax; consequently, apixaban was discontinued, and a thoracic drain was inserted. She repeatedly had an intermittent fever of 40.3 °C, and contrast-enhanced computed tomography detected an abscess formation at the left parotid gland, pterygoid muscle group, and masseter muscle. After Lemierre's syndrome was diagnosed in combination with the abovementioned jugular vein thrombus, clindamycin was replaced with meropenem, and vancomycin was increased. Swelling of the lower part of the left ear became prominent with delay and peaked at approximately the 16th day. The subsequent treatment course was favorable, and she was discharged on the 41st day. CONCLUSION: Clinicians should consider Lemierre's syndrome as the differential diagnosis of internal jugular vein thrombosis occurring during sepsis, even though an antibiotic is administered or a primary infection site is anything besides the oropharynx.

Atypical involvement of the thyro-linguo-facial vein in Lemierre syndrome.

Fusobacterium necrophorum is a Gram-negative anaerobic bacterium that can lead to severe infection in young patients even without immunodeficiency. Due to the length of time for isolation and speciation of this Gram-negative bacillus (typically 5-8 days), and its potential mortality, broad-spectrum antibiotic therapy should be started without delay. With a cervical thrombosis, even on an unusual site and with a standard condition such as tonsillitis, Lemierre syndrome should be considered. We report a case of Lemierre syndrome in a previously healthy young woman.

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.

Fusobacterium necrophorum oral infections - A need for guidance.

F. necrophorum, a gram-negative obligate anaerobe, causes pharyngotonsillitis, peritonsillar abscess and the Lemierre Syndrome as well as other significant infections. Clinical information on this bacterium has increased dramatically over the past 20 years, yet no standard guidance exists for treating these infections. While data support F. necrophorum as a cause of pharyngotonsillitis, no consensus exists on the clinical importance of these findings especially in the 15-30 age group. Similarly, recent data find this bacterium the most frequent and most likely to recur in peritonsillar abscess for that age group. Should this impact how we treat these patients? Finally, we have no studies of either antibiotics or anticoagulation for the Lemierre Syndrome. Thus, each physician making the diagnosis of the Lemierre Syndrome chooses antibiotics (and their duration) and whether or not to anticoagulate without guidance. Infectious disease specialists and hospitalists would benefit from consensus expert opinions based on reviewing data on these infections.

Fusobacterium necrophorum-induced orbital cellulitis with intracranial involvement: a case report and review of the literature.

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.
