Septic thrombosis of cavernous sinus extended to the ipsilateral internal jugular vein and transversal sinus with favorable outcome: Clinical and radiological features of a Lemierre syndrome

High risk and low prevalence diseases: Cavernous sinus thrombosis

INTRODUCTION

Cavernous sinus thrombosis (CST) is a serious condition that carries with it a high rate of morbidity and mortality.

OBJECTIVE

This review highlights the pearls and pitfalls of CST, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence.

DISCUSSION

CST is a potentially deadly thrombophlebitic disease involving the cavernous sinuses. The most common underlying etiology is sinusitis or other facial infection several days prior to development of CST, though other causes include maxillofacial trauma or surgery, thrombophilia, dehydration, or medications. Staphylococcus aureus, streptococcal species, oral anaerobic species, and gram-negative bacilli are the most frequent bacterial etiologies. The most prevalent presenting signs and symptoms are fever, headache, and ocular manifestations (chemosis, periorbital edema, ptosis, ophthalmoplegia, vision changes). Cranial nerve (CN) VI is the most commonly affected CN, resulting in lateral rectus palsy. Other CNs that may be affected include III, IV, and V. The disease may also affect the pulmonary and central nervous systems. Laboratory testing typically reveals elevated inflammatory markers, and blood cultures are positive in up to 70% of cases. Computed tomography of the head and orbits with intravenous contrast delayed phase imaging is recommended in the ED setting, though magnetic resonance venography demonstrates the highest sensitivity. Management includes resuscitation, antibiotics, and anticoagulation with specialist consultation.

CONCLUSION

An understanding of CST can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Endogenous endophthalmitis secondary to Lemierre's Syndrome originating from pharyngotonsillitis

PURPOSE

The purpose of this article is to report a case of Lemierre's Syndrome producing unilateral endogenous endophthalmitis in a healthy, young woman with a history of tonsillitis.

CASE REPORT/OBSERVATIONS

A 17-year-old healthy woman developed fever after a few days of sore throat. She later developed pneumonia with septic signs, leading to admission to the Intensive Care Unit. Lemierre Syndrome was diagnosed due to multiple septic pulmonary emboli and signs of sepsis following a recent episode of tonsillitis. During hospitalization, the patient complained of decreased visual acuity and floaters in her left eye. Ophthalmological examination revealed papillary edema, vitritis, foci of chorioretinitis in the macula and Roth's spots, confirming the diagnosis of endogenous endophthalmitis. Subsequently, she underwent appropriate treatment, progressing satisfactorily.

CONCLUSION AND IMPORTANCE

Although ophthalmological manifestations are rare, due to the pathophysiological characteristics of Lemierre's Syndrome, all patients should underwent standard ophthalmologic assessment, even in the absence of ophthalmic symptoms or visible findings, as part of a multidisciplinary management approach.

Lemierre's Syndrome Caused by Streptococcus milleri Group

A 64-year-old woman was transported to the emergency room with a headache and fever. She presented with a right ocular protrusion, hyperemia, and tenderness in the neck. Contrast-enhanced MRI of the head showed a high DWI signal in the bilateral sphenoid sinuses and contrast defects along the bilateral internal jugular and superior ophthalmic veins. Blood and CSF cultures revealed Streptococcus milleri group. Surgery was performed for Lemierre's syndrome secondary to sphenoid sinusitis. The patient was treated with antibiotics and anticoagulant therapy, but a duodenal ulcer and brain abscess thereafter developed. However, multidisciplinary endoscopic and surgical treatment saved her life.

Lemierre's syndrome with isolated external jugular vein thrombosis caused by Streptococcus intermedius

An 85-year-old woman with a history of rheumatoid arthritis fell due to unsteadiness and visited our emergency room due to head injury. The patient had minor head trauma and lip and oral cavity injuries, and she presented with fever. Laboratory tests showed high inflammatory marker levels. Moreover, there were indicative of urinary tract infection. Thus, the patient was admitted to our hospital. Blood cultures performed upon admission revealed the presence of Streptococcus intermedius, and contrast-enhanced computed tomography scan showed solitary right external jugular vein thrombosis and multiple abscesses in both lungs. Hence, the patient was diagnosed with Lemierre’s syndrome, and antimicrobial agents and anticoagulants were administered. The patient developed left pleurisy due to inflammation caused by lung abscesses, which improved with thoracic drainage. Her condition improved satisfactorily, and she was then discharged. There are only few studies about Lemierre’s syndrome caused by S. intermedius and even lesser cases involving external jugular vein thrombosis. Herein, we report a relatively rare case of Lemierre’s syndrome with isolated external jugular vein thrombosis.

Septic cavernous sinus thrombosis: A review

Septic cavernous sinus thrombosis (SCST) is a rare, yet severe, process typically arising from infections of the paranasal sinuses (predominately ethmoid and/or sphenoid sinusitis) and less commonly, otogenic, odontogenic, and pharyngeal sources. Clinical symptoms of SCST arise from obstruction of venous drainage from the orbit and compression of the cranial nerves within the cavernous sinus. In the preantibiotic era SCST was considered universally fatal (80-100%); however, with the introduction of antibiotics the overall incidence, morbidity, and mortality of SCST have greatly declined. In spite of dramatic improvements, morbidity and mortality remain high, with the majority of patients experiencing neurological sequalae, highlighting the severity of the disease and the need for prompt recognition, diagnosis, and treatment. Here we review of the literature on SCST with a focus on the current recommendations and recent evidence for diagnostic and medical management of this condition.

Cavernous sinus thrombosis: a late complication of head and neck surgery

Cavernous sinus thrombosis is a rare but fatal condition arising due to various infectious and noninfectious causes. Although its incidence is very low in the setting of head and neck surgery, including radical neck dissection, a high index of suspicion with prompt treatment is the key to a successful outcome. We report a case of a 50-year-old woman with a chondrosarcoma of left lower alveolobuccal complex who underwent en bloc tumour resection with infratemporal fossa clearance and left modified radical neck dissection. Subsequently, she developed cavernous sinus thrombosis, which was successfully managed with a multidisciplinary approach. This case highlights the importance of high clinical suspicion in the postoperative setting to diagnose this potentially lethal complication.

Lemierre's syndrome involving milleri group streptococci: further insight into age and aetiology

Lemierre's syndrome (LS) is a suppurative thrombophlebitis of the internal jugular vein secondary to otorhinolaryngologic infection. It is classically associated with the Gram-negative anaerobe Fusobacterium necrophorum (FN) and is thought to be a disease of young people. Here, we describe the case of a 56-year-old woman with LS involving milleri group streptococci (MGS), which has been reported only 13 times since it was first observed in 2003. Subgroup analysis of all published cases of LS involving MGS demonstrated these patients were significantly older than those involving FN (median age 49 years versus 18 years, p = 0.007, IQR 36-58 years), although this finding is limited by publication bias. This report clarifies a 2014 hypothesis regarding the relationship between age and aetiology in this rare disease. While FN remains the most common cause of LS overall, empiric antibiotic therapy should also cover oral streptococci such as MGS, even in younger adults.

A Systematic Review of Lemierre's Syndrome With a Focus on Ophthalmologic Complications

Lemierre's syndrome (LS), once known as "the forgotten disease," is a rare and potentially life-threatening condition that has had a gain in incidence over the last 30 years due to a variety of factors that could include changes in antibody prescription patterns, particularly in regard to the treatment of pharyngitis/tonsillitis. Due to its low incidence and broad spectrum of symptoms, LS does not have an obvious clinical diagnosis and can confuse the clinician managing the patient. Furthermore, it is equally difficult to treat patients suffering from LS as it requires a multidisciplinary approach from multiple subspecialties. Thus, communication between hospitalists, radiologists, otolaryngologists, neurologists, and ophthalmologists is critical towards quickly diagnosing the disease condition so that prompt antibiotics, anticoagulation, and surgical intervention can occur. Atypical presentations can also exist, making the diagnosis and management exponentially more challenging. Ophthalmologic symptoms are a particularly rare and atypical presentation of LS. These rare symptoms in LS can be terrifying for patients and providers alike; yet, there does not seem to be any modern medical literature that summarizes ophthalmologic complications for LS patients. To our knowledge, this is the first systematic review of LS with a focus on ophthalmologic complications that has been done. The main objective of this review paper is to provide an up-to-date literature review of LS epidemiology, pathophysiology, diagnosis, and treatment while also performing a novel systematic review of reported cases of LS with ophthalmological complications. We hope to bring more awareness towards LS and its atypical presentations so that physicians will be better able to rapidly diagnose and treat their patients in order to minimize long-term morbidity and mortality.

A Rare Case of Lemierre's Syndrome Caused by Streptococcus Intermedius, Presenting as an Epidural Abscess

Lemierre's syndrome is a rare but life-threatening condition characterized by an oropharyngeal infection typically secondary to Fusobacterium necrophorum resulting in septic thrombophlebitis of the internal jugular vein. Streptococcus intermedius is a particularly rare cause of Lemierre's syndrome with only a few cases reported in the literature. Here we describe a rare case of Lemierre's syndrome, caused by Streptococcus intermedius, likely secondary to an odontogenic infection, found to have a cervical epidural abscess with concomitant large retropharyngeal and prevertebral abscesses on presentation, in whom the clinical course was further complicated by an extensive cerebral venous sinus thrombosis. However, despite grave complications, early diagnosis and appropriate emergency management including intravenous antibiotics and surgical intervention led to a successful recovery, thus demonstrating that aggressive measures can potentially lead to a favorable outcome. 

Cavernous sinus thrombosis caused by Streptococcus constellatus-associated Lemierre syndrome presenting as an isolated abducens nerve palsy

Purpose

To describe a patient with Streptococcus constellatus-associated Lemierre syndrome complicated by eventual cavernous sinus thrombosis (CST) that manifested as an isolated abducens nerve palsy.

Observations

A patient with a history of heavy alcohol use presented with Lemierre syndrome caused by an odontogenic infection due to Streptococcus constellatus. Despite initiation of intravenous antibiotics and eventual eradication of her bacteremia, she developed an isolated abducens nerve palsy on hospital day 7 due to associated CST.

Conclusions and Importance

CST is a rare complication of odontogenic infection and Lemierre syndrome. This case demonstrates the potential for primary odontogenic infections to progress to life- and sight-threatening diseases. This case also illustrates the importance of considering uncommon pathogens as the etiology of CST based on the suspected source of primary infection.

Bilateral abducens nerve palsy due to septic thrombophlebitis

Purpose

To report a case of septic thrombophlebitis producing bilateral abducens nerve palsy.

Observation

A 65 year-old woman with recent sinus surgery experienced the onset of horizontal diplopia during treatment for bacteremia. Computer tomography of head and a neck ultrasonography showed right internal jugular vein occlusion. Ophthalmology examination was consistent with bilateral abducens nerve palsy. She was treated with systemic antibiotics and antiplatelet therapy with resolution of the internal jugular vein occlusion. The diplopia improved over a six-months.

Conclusion and importance

Our patient had Lemierre syndrome with an unusual presentation. The patient was treated for septic thrombophlebitis with a resolution of her ocular symptoms.
