We present a case of invasive Fusobacterium infection that meets all criteria for Lemierre syndrome except lacking internal jugular thrombosis. [ncbi.nlm.nih.gov]

• Infectious Mononucleosis

  History The patient was first evaluated at his school clinic where a presumptive diagnosis of infectious mononucleosis (IM) was made and he was treated with oral steroids and NSAIDs. [consultant360.com]

• Streptococcal Pharyngitis

  Recent evidence (3, 4) suggests that Fusobacterium necrophorum pharyngitis occurs as often as streptococcal pharyngitis in patients aged 15 to 30 years. [annals.org]

  With the introduction of antibiotics in the 1940s and their widespread use for streptococcal pharyngitis, the incidence of Lemierre’s syndrome fell dramatically. [link.springer.com]

• Fatigue

  A common 1- to 2-week history of fever, sore throat, neck pain, and fatigue was observed in all patients. Patient 1 developed right facial swelling, neck tenderness, trismus, and tonsillar exudate. [ncbi.nlm.nih.gov]

  Unlike many who suffer from the disease, Iniguez was diagnosed with Lemierre's Syndrome, a rare and deadly disease that often goes overlooked by physicians because it presents with such basic symptoms, such as fever, shortness of breath and fatigue. [petaluma360.com]

  This case report describes a 37-year-old female patient who presented with edema and pain in the right hemiface with onset 3 days previously and progressive fatigue and dyspnea since the previous day. [jvascbras.org]

• Cerebral Palsy

  In the other side, and despite an aggressive therapy, an 18-month-old infant developed cerebral palsy. [ncbi.nlm.nih.gov]

• Nausea

  Gastrointestinal complaints such as abdominal pain, nausea, and vomiting were common (49.5% of cases). An elevated white blood cell count occurred in 75.2% of cases. [ncbi.nlm.nih.gov]

  Often there is abdominal pain, diarrhea, nausea and vomiting during this phase. These signs and symptoms usually occur several days to 2 weeks after the initial symptoms. [en.wikipedia.org]

  Abdominal pain with nausea, vomiting, and diarrhea can be seen. End-organ damage can also be detected, including decreased urine output, as well as spleen and liver enlargement. Occasionally, meningitis will also occur. [emdocs.net]

• Visual Impairment

  An 86-year-old patient was hospitalized for fever and left acute orbital syndrome (red eye with moderate visual impairment, chemosis, ophthalmoplegia without proptosis, or any fundus involvement). [ncbi.nlm.nih.gov]

• Insect Bite

  Physical Examination At the time of admission the patient denied cough, chest pain, shortness of breath, history of insect bites to the neck, any recent travel, sick contacts, or recent surgeries. [consultant360.com]

• Myalgia

  Am Fam Physician. 2007 Apr 1;75(7):979-980. to the editor : A 24-year-old man presented with intermittent fevers and generalized myalgias preceded by sore throat, neck pain, and rhinorrhea several weeks earlier. [aafp.org]

• Oligoarthritis

  Postma, A 25-year-old male with oligoarthritis as the first sign of Lemierre’s syndrome, Infection, 10.1007/s15010-010-0071-7, 39, 1, (87-89), (2011). [doi.org]

• Neck Swelling

  Finally, pediatricians, internists, family physicians, and emergency department physicians should know the red flags for adolescent and young adult pharyngitis: worsening symptoms or neck swelling (especially unilateral neck swelling). [ncbi.nlm.nih.gov]

  Neck swelling may be evident. Bacteremia and distal infective thromboembolism is common (lungs most commonly affected, however almost any organ may be involved 4 ). [radiopaedia.org]

  The 2 major red flags in adolescent and young adult pharyngitis are worsening symptoms or neck swelling. If the patient has bacteremic symptoms, treat either with a combination of penicillin and metronidazole or with clindamycin alone. [annals.org]

• Kidney Failure

  After infection starts to set in, symptoms worsen and include: High fever Rigors (chills and shivering) Swollen lymph nodes in the neck Joint pain Complications can lead to: Lung abscess Brain abscess Kidney failure Septic shock Acute respiratory distress [clicks.co.za]

  failure Liver failure Abscesses in the spleen Pockets of infection in the muscle and skin Meningitis Brain abscesses Diagnosis Lemierre's syndrome is diagnosed through blood tests that identify the bacteria causing the observed symptoms. [everydayhealth.com]

• Headache

  A 76-year-old Japanese male presenting with high fever, headache, and disturbance of consciousness was hospitalized. [ncbi.nlm.nih.gov]

  The latter usually appears with nonspecific symptoms, the most common being frontal headache. 4 The culture was positive for S. viridans. Thrombosis/occlusion of the internal carotid artery is a very rare complication. [elsevier.es]

  We report a case of a 6-year-old boy, who presented with fever and headache with a history of sore throat. [hindawi.com]

  Some cases will also present with meningitis, which will typically manifest as neck stiffness, headache and sensitivity of the eyes to light. [en.wikipedia.org]

  His headache was terrible, almost as bad as it had been in the hospital, where it had brought the man to tears — something his wife had never seen before. [well.blogs.nytimes.com]

• Generalized Tonic-Clonic Seizure

  Her hospital course was complicated by a middle cerebral artery distribution infarction and subsequent hemorrhagic conversion with generalized tonic clonic seizures managed by levetiracetam. [ncbi.nlm.nih.gov]

A high index of suspicion is needed to consider this diagnosis in the workup of pharyngitis and should be aggressively treated once identified. [ncbi.nlm.nih.gov]

Further imaging workup was then arranged to identify any potential source of the septic emboli but echocardiogram did not reveal any heart valve vegetation. Figure 2. [hkmj.org]

After initial workup and physical examination, the ED discharged him with same diagnosis of IM. [consultant360.com]

Workup for the presence of a hypercoagulable state was negative, and the patient was anticoagulated with enoxaparin. He was discharged home to complete a 6-week course of antibiotics and anticoagulation. [link.springer.com]

Treatment with broad-spectrum antibiotics is the primary choice of treatment of Lemierre syndrome. Surgery is indicated in case of abscess formation. [ncbi.nlm.nih.gov]

Anticoagulation treatment with a vitamin K antagonist was prolonged for 6 months. [signavitae.com]

Even without internal jugular thrombosis, the same mechanism of disease exists, and therefore, the same morbidity, prognosis, and treatments are applicable, hence the suitable term incomplete Lemierre syndrome. [ncbi.nlm.nih.gov]

If unrecognised and untreated, systemic dissemination can occur with a dismal prognosis; studies from the modern era still report mortality rates as high as 18% 8. [radiopaedia.org]

In 81% of the cases, the Fusobacterium necrophorum is the most frequent etiologic agent. Fever is the most common symptom, but it can depending on the primary infection, tonsillitis, mastoiditis or odontogenic infection. [ncbi.nlm.nih.gov]

Fusobacterium necrophorum is the usual etiologic agent. The disease progresses in several steps. The first stage is the primary infection, which is usually a pharyngitis (87.1% of cases). [doi.org]

Etiology: This syndrome is caused by extension of infection into the carotid space. source of infection could be any of the deep neck space infections. Clinical features: 1. [sites.google.com]

Further epidemiologic research is needed on both F. necrophorum pharyngitis (especially clinical presentation) and the Lemierre syndrome. Clinicians need reliable diagnostic techniques for F. necrophorum pharyngitis. [ncbi.nlm.nih.gov]

Finally we had an epidemiologic study which defined the extent of this disease. I have extrapolated the Danish data to the United States. [medrants.com]
