Ophthalmic complications of Lemierre syndrome

Case of Lemierre's Syndrome Presenting With Neuro-Ophthalmologic Complications That Worsened After Stopping Corticosteroids

Lemierre's syndrome (LS) is a rare disorder that manifests as septic internal jugular thrombophlebitis following a recent oropharyngeal infection. This article details a unique case of LS, where the patient presented to the emergency room with complaints of vomiting, headache, diplopia, and left eye pain. Due to a history of sore throat, headache, neck pain, fever, and nausea five days prior to admission, the patient was initially treated with amoxicillin/clavulanate for suspected tonsillitis. A positive meningeal sign and elevated temperature were observed during the clinical examination. Lumbar puncture (LP) was deferred based on imaging indicating potential increased intracranial pressure (ICP). Nevertheless, the patient received vancomycin, ceftriaxone, and dexamethasone as an initial course of treatment for presumed bacterial meningitis. Significant improvement was observed within the first four days of admission, with no subsequent episodes of fever, nausea, or headache. However, upon discontinuation of corticosteroid therapy, the patient experienced severe headaches and frequent vomiting. An urgent brain CT scan confirmed the extension of the left internal jugular vein (IJV) thrombosis to the ipsilateral sigmoid sinuses. Metronidazole and anticoagulant medication were initiated upon LS diagnosis. There is a paucity of discussions on corticosteroid use in LS, with no definitive statistics in the current literature. This case underscores the importance of recognizing and effectively managing interconnected clinical manifestations.

Cardiac and Cerebral Arterial Complications of Lemierre Syndrome: Results from a Systematic Review and Individual Patient Data Meta-analysis

Background  Lemierre syndrome is a potentially life-threatening disease, which affects otherwise healthy young adults and adolescents. It is characterized by acute neck vein thrombosis and septic embolism, usually complicating a bacterial infection. Data on the syndrome are sparse, particularly concerning arterial complications.

Methods  We evaluated the frequency and patterns of cerebral arterial and cardiac involvement (“arterial complications”) in an individual patient level cohort of 712 patients, representing all cases described over the past 20 years in the medical literature who fulfilled the criteria: (1) bacterial infection in the neck/head site and (2) objectively confirmed thrombotic complication or septic embolism. The study outcomes were defined as all-cause in-hospital deaths and the occurrence of clinical sequelae at discharge or in the postdischarge period.

Results  A total of 55 (7.7%) patients had an arterial complication. The most frequent arterial complications were carotid involvement (52.7%), stroke (38.2%), and pericardial complications (20%). Patients with an arterial involvement were more likely to be treated with a greater number of antibiotics (23 vs. 10%) and to receive anticoagulation. In addition, patients with arterial complications had a greater risk of all-cause death ( n  = 20/600, 3.3% vs. n  = 6/52, 12%; odds ratio [OR]: 3.8; 95% confidence interval [CI]: 1.5–9.9) and late clinical sequelae ( n  = 49/580, 9.0% vs. n  = 15/46, 35%; OR: 5.2; 95% CI: 2.65–10.37).

Conclusions  While Lemierre syndrome is known to be primarily characterized by venous thromboembolic events, our results suggest that local or distant arterial complications may occur in approximately one-tenth of patients and may be associated with a greater risk of long-term sequelae and death.

Severe case of Lemierre syndrome with multiple neurological and ophthalmological sequelae

A 56-year-old man was admitted to intensive care with septic shock, multiple facial abscesses and thrombophlebitis of the right internal jugular vein with extensive intracranial extension. A diagnosis of Lemierre syndrome due to Streptococcus anginosus was made and treatment initiated with high-dose ceftriaxone and metronidazole, along with surgical debridement. His admission was complicated by raised intraocular pressures and visual loss requiring bilateral canthotomies. Despite therapeutic anticoagulation with enoxaparin, he also developed an ischaemic basal ganglia infarct. After a prolonged and complex hospital stay, the patient was later readmitted with an intracerebral abscess requiring surgical excision and a second course of antibiotics. This case highlights the value of early recognition of this rare but potentially life-threatening condition, considerations around anticoagulation and antibiotic decisions, and the importance of close multidisciplinary follow-up even after discharge from hospital.
