Lemierre’s syndrome (LS) is a rare life-threatening infective condition typically starting with an oropharyngeal infection causing thrombophlebitis and metastatic abscesses. The most common aetiology of LS is Fusobacterium necrophorum; however, it can also occur after infection with other organisms. LS mainly affects young healthy adults. The initial infection site can be in the head and neck or in the abdomen. The morbidity rate of this disease is high despite aggressive treatments. In this article, we report a 63-year-old male patient with uncontrolled diabetes mellitus, presenting with Klebsiella pneumoniae infection-induced necrotizing fasciitis on the right side of the neck, leading to LS.

Lemierre syndrome is caused by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein and frequent metastatic infections. The usual etiologic agent is Fusobacterium necrophorum. Lemierre syndrome was a common disease with a high mortality rate in the pre-antibiotic era. Since the advent of antibiotics and their widespread use for the treatment of pharyngeal infections, there has been a substantial decrease in the incidence of this malady and it has become a "forgotten disease". Prompt diagnosis and antibiotic therapy for Lemierre syndrome is essential to avoid morbidity and mortality. We describe here a case of Lemierre syndrome with multiple septic pulmonary emboli.

Lemierre syndrome is caused by an infection in the oropharyngeal region with subsequent thrombophlebitis in the internal jugular vein. The thrombus from the thrombophlebitis can invade other vital organs, such as liver, lungs, or joints, resulting in secondary infection, which further exacerbates the fatal prognosis of this syndrome. Lemierre syndrome, also called postanginal sepsis or necrobacillosis, was first reported by Dr. Lemierre in 1936. In his report, Lemierre mentioned that out of 20 patients who suffered from this syndrome, only two survived. He also stated that all of the 20 patients complained of infections in the palatine tonsils and developed sepsis and thrombophlebitis in the internal jugular vein. Once called a "forgotten disease," this syndrome showed a very high mortality rate until usage of antibiotics became prevalent. In this case report, the authors present a 71-year-old female patient who suffered from Lemierre syndrome with thrombosis extended to the right sigmoid sinus.

Lemierre's syndrome is characterized by anaerobic bacterial infection in the head and neck, causing thrombophlebitis of the jugular vein. This disease is usually associated with a history of pharyngitis. The most common pathogens are Fusobacterium species, particularly Fusobacterium necrophorum. Lemierre's syndrome is seen most commonly in teenagers and young adults. We present a case report of a 67-year-old man with an atypical clinical manifestation of an uncommon pathogen in Lemierre's syndrome with epilepsia partialis continua.

Lemierre syndrome is characterized by anaerobic bacterial infection in the head and neck and clinical or radiological evidence of internal jugular vein thrombophlebitis. The most common pathogens are Fusobacterium species, particularly Fusobacterium necrophorum. Septic emboli resulting from infected thrombophlebitis of the internal jugular vein leads to metastatic infections involving lung, liver, kidney, bone and central nervous system. The accurate diagnosis and treatment is important because it may be associated with a high mortality rate if untreated. We present a case of 28-year-old man with an atypical history for the diagnosis of Lemierre syndrome, which showed no definite evidence of internal jugular thrombophlebitis.

Lemierre syndrome is a rare, but potentially life-threatening complication of oropharyngeal infection. This syndrome is characterized by oropharyngeal infection leading to internal jugular vein thrombosis and multiple pulmonary septic emboli. It is commonly caused by an anaerobic pathogen such as Fusobacterium necrophorum. Early diagnosis and appropriate antibiotic treatment make a world of difference in preventing fatal outcomes. Here we present the case of a 25-year-old man with acute tonsillitis that was complicated with Lemierre syndrome. Emergency physicians should consider the possibility of Lemierre syndrome in young patients with initial oropharyngeal infection with neck swelling and pulmonary symptoms.
