Necrotizing Lip Infection Causing Septic Thrombophlebitis of the Neck: A Rare Variant of Lemierre Syndrome

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.

Lemierre syndrome: case report

Lemierre syndrome is characterized by septic thrombophlebitis of the internal jugular vein, after an oropharyngeal infection, with septic embolization to the lungs or other organs. 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. She had had tooth 48 extracted 3 days previously. Physical examination at admission found tachypnea, with 60% saturation (in room air), edema at the angle of the right mandible, diffuse reduction of vesicular murmur, and calves free from clubbing. Angiotomography of the chest and laboratory tests were compatible with septic emboli, and cervical computed tomography confirmed a diagnosis of septic thrombophlebitis of the internal jugular vein. She was managed with antibiotics and given treatment for her symptoms. Lemierre syndrome most often occurs in young men and there is embolization to the lungs in up to 97% of cases. Rarely, the etiology of this syndrome may be tooth extraction. Computed tomography is the imaging method most often used for diagnosis and treatment is basically antibiotic. Surgery is thus rarely necessary.

Lemierre’s Syndrome Due to Methicillin-Resistant Staphylococcus aureus

Lemierre’s syndrome is an uncommon and potentially fatal complication of oropharyngeal and facial infections. It involves an associated septic thrombophlebitis, bacteremia, and septic emboli. Traditionally, compromise of the internal jugular vein has been described in conjunction with an infection caused by anaerobes, especially, Fusobacterium necrophorum. In recent years, however, variant forms have been appearing, including other vessel compromise and other etiologic agents. We present the case of Lemierre’s syndrome in a 31-year-old male with facial vein thrombosis, septic emboli to the lungs, and bacteremia caused by methicillin-resistant Staphylococcus aureus. We hope that this case will raise awareness about variant presentations and promote a timely diagnosis and appropriate treatment of this potentially fatal infection.

Facial vein thrombophlebitis: A case report and literature review

Septic thrombophlebitis of the facial vein (STFN) commonly presents with facial erythema, tenderness, and swelling above the involved vessel. Due to its rarity, diagnosis and treatment remain a challenge. Lemierre syndrome (LS), which consists of a triad of internal jugular vein thrombophlebitis, septicemia, and distant septic emboli, is a more common entity of which physicians are more familiar. Whether tonsillitis-related STFN is actually LS in a different anatomical area and shares the same characteristics is still left to be answered. We present a case of STFN with a review of all cases reported in the literature.

Senile Lemierre syndrome complicated with descending necrotizing mediastinitis: A case report

RATIONALE

Senile patients with LS complicated with DNM are rarely seen in clinical practice, and extensive cervical incision and drainage plus administration of effective antibiotics are the basis for treatment. Currently, the treatment controversy mainly has focused on whether mediastinal incision and drainage is necessary for patients with type I DNM, and whether anticoagulation therapy is required for jugular venous emboli and distant metastatic emboli induced by LS.

PATIENT CONCERNS

A female, 76 years old, developed pain of tonsil on right side 5 days ago, and felt that the pain aggravated complicated with dysphagia and swelling pain of neck on both sides since then.

DIAGNOSES

She was diagnosed with LS complicated with type I DNM.

INTERVENTIONS

Tazobactam and Piperacillin 4.5 q8h and Ornidazole 100 ml q6h ivgtt were administered empirically,and secondary extensive cervical incision and drainage was performed under general anesthesia, after which low molecular weight heparin 4250 U q12h SC was administered. G test was performed 3 days later, which showed (1,3)-β-D-glucan >1000 pg/ml. Bridging anticoagulation therapy, low molecular weight heparin 4250 U q12h SC, and Warfarin 2.5 mg qd po were given one week later. Low molecular weight heparin SC was discontinued and only Warfarin po was administered after treatment of bridging therapy for 3 days.

OUTCOMES

CT of head and neck was reexamined on post-admission d24 and revealed that neck infection was improved on both sides, jugular vein distension on right side was restored to normal, abscess and pneumatosis of superior mediastinum were improved, distension of pulmonary artery on both sides was normalized, WBC was 9.94×109/L, neutrophil count was 4.43×109/L, CRP level was 9.8mg/L, D-D level was 0.81mg/L, PCT level was 0.800ng/mL and G test suggested (1,3)-β-D-glucan pf 27.1 pg/mL.

LESSONS

Concomitant use of anticoagulants on the basis of repeated cervical incision and drainage + administration of effective antibiotics can obtain excellent therapeutic efficacy in the treatment of patient with LS complicated with type I DNM.
