A Rare Intersection of Septic Cavernous Sinus Thrombosis and Subarachnoid Hemorrhage: Insights from the Case of a 70-Year-Old Patient.

We describe a rare and complex case of septic cavernous sinus thrombosis (SCST) in a 70-year-old patient who initially presented with ocular symptoms that rapidly progressed to severe intracranial vascular complications, including subarachnoid hemorrhage (SAH). Despite the use of broad-spectrum antibiotics and anticoagulants, the patient's condition deteriorated. SCST, often caused by sinus infections, presents a significant diagnostic and therapeutic dilemma, with mortality rates exceeding 20%. This report underscores the diversity of clinical presentations, ranging from mild headaches to severe cranial nerve deficits, that complicate diagnosis and treatment. The inability to detect any aneurysms in our patient using magnetic resonance imaging (MRI) and computed tomography angiography (CTA) may indicate an alternative pathogenesis. This could involve venous hypertension and endothelial hyperpermeability. This case illustrates the need for personalized treatment approaches, as recommended by the European Federation of Neurological Societies, and the importance of a multidisciplinary perspective when managing such intricate neurological conditions. Our findings contribute to the understanding of SCST coexisting with SAH.

Cavernous Sinus Thrombosis and Blindness After Simple Tooth Extraction in Patient Who Recovered From Coronavirus 2019: A Case Report.

The pandemic Coronavirus 2019 is a disease transmitted either by droplets from a person's sneeze or cough or direct spread; also known as severe acute respiratory syndrome coronavirus-2. Although the morbidity of the disease is mainly related to respiratory distress, the associated inflammatory response can induce various coagulopathies despite an anticoagulant therapy. The authors are documenting a case of a diabetic patient who recovered from Coronavirus 2019 and is on prophylactic anticoagulant therapy after routine extraction of a maxillary second molar that progressed to unilateral cavernous sinus thrombosis and loss of vision.

When the Problem Became the Solution.

We present a unique case where a young man developed subtle cavernous sinus thrombosis (CST) due to underlying hypercoagulable state. He also had coexisting frontal lobe brain dural arteriovenous fistula (bdAVF). After CST developed, venous drainage from the optic nerve was redirected into the frontal lobe which was already under high venous pressure because of preexisting bdAVF. This caused backflow of venous blood into the optic nerve causing massive persistent optic nerve head swelling. Presumed acute venous hypertension event within bdAVF caused frontal mass effect presenting as seizure leading to thrombosis of bdAVF.

Comment faire d'un problème une solution. Nous voulons présenter ici le cas unique d'un jeune homme chez qui une thrombose du sinus caverneux s'est développée en raison d'une condition sous-jacente d'hypercoagulabilité. Ajoutons également que le lobe frontal de son cerveau donnait à voir des fistules artério-veineuses durales. Une fois développé ce type de thrombose, on a procédé à un drainage veineux à partir du nerf optique, drainage ensuite redirigé dans le lobe frontal, lequel faisait déjà face à des conditions de pression veineuse élevée à cause de ces fistules. Cela a entraîné le refoulement de sang veineux dans le nerf optique, ce qui a provoqué en retour une grave et persistante enflure de la tête du nerf optique. À cet égard, on peut présumer qu'une manifestation aigüe d'hypertension veineuse dans ces fistules a causé l'apparition de cet effet de masse du lobe frontal se manifestant par des crises convulsives, ce qui a fini par engendrer la thrombose des fistules artério-veineuses durales.

Impact of superior ophthalmic vein thrombosis: a case series and literature review.

Purpose: To present nine new cases of superior ophthalmic vein thrombosis (SOVT) and compare these with the literature, and to assess the impact of SOVT for the clinician. Methods: Using the data bases of the Department of Ophthalmology of the AMC, we searched for patients with radiologically evidenced SOVT between January 2006 and December 2014. In addition, a PubMed search, using the mesh term 'superior ophthalmic vein thrombosis', was done. Results: We found nine patients with SOVT. In three patients, SOVT was related to dural arteriovenous fistulae. In one patient, it was caused by the acute reversal of warfarin by vitamin K. In two patients, an infectious cause was found. In three patients, the cause of SOVT was not found despite screening for coagulation and other disorders. All patients presented with eyelid swelling, proptosis, and/or motility impairment. We found complete recovery in four patients. Three patients had mild sequelae and two patients had severe visual impairment. In the literature, we found 60 cases reporting on SOVT with various aetiologies. Clinical presentation, treatment modalities, and outcomes were comparable to our findings. Conclusion: Our case series and literature review show that SOVT can occur simultaneously with cavernous sinus thrombosis (CST) but can also be a separate entity. Clinical presentation can mimic orbital cellulitis (OC) or CST and when no signs of OC can be found, an alternative cause for SOVT should be sought. When timely and adequate treatment is conducted, the prognosis is predominantly favourable.

Cavernous Sinus Thrombosis in Children: Imaging Characteristics and Clinical Outcomes.

BACKGROUND AND PURPOSE: Cavernous sinus thrombosis (CST) is a rare life-threatening cerebrovascular disease known to cause carotid artery narrowing (CAN) and arterial ischemic stroke. The imaging features of CST and related complications have been reported in adults, but rarely in children. METHODS: We performed a retrospective review of children with imaging confirmed CST from 2003 to 2014, describing presenting symptoms, imaging findings, and treatment. RESULTS: Ten patients with CST were identified. All had CAN and 6 of 10 developed infarcts. Of 8 patients treated with anticoagulation therapy, 3 developed new infarcts. None required discontinuation of anticoagulation therapy because of bleeding. Visual impairment secondary to infectious neuritis was common. Imaging characteristics include cavernous sinus expansion, filling defects, restricted diffusion, arterial wall enhancement, empyema, superior ophthalmic vein enlargement and thrombosis, orbital cellulitis, and pituitary inflammation. CAN resolved in 60% of cases. Outcomes were mostly good, with a modified Rankin Scale score of ≤1 for 7 of 10 patients at discharge and 1 death. CONCLUSIONS: CAN and infarcts were common in this modest cohort of children with CST. Despite the high incidence of CAN and infarction, outcomes were often favorable. Although this is the largest cohort of childhood CST reported to date, large multicenter cohorts are needed to confirm our findings and determine the preferred therapeutic strategies for childhood CST.

Optic nerve sheath fenestration for the treatment of papilledema secondary to cerebral venous thrombosis.

A 16-year-old adolescent girl with multiple risk factors for thrombosis presented with acute onset of headache, decreased vision, and papilledema. Evaluation demonstrated cerebral venous thrombosis (CVT) involving the left transverse and sigmoid sinuses and left internal jugular vein. Following bilateral optic nerve sheath fenestration (ONSF), she experienced improvement in vision and resolution of papilledema. In selected cases, ONSF is an effective surgical option for the treatment of papilledema due to CVT after medical treatment has failed.

Lemierre syndrome secondary to community-acquired methicillin-resistant Staphylococcus aureus infection associated with cavernous sinus thromboses.

BACKGROUND: Lemierre Syndrome (LS) is a highly aggressive rare disease process with a predilection for young, healthy adolescents. Often beginning with a primary cervicofacial infection, LS rapidly progresses to thrombophlebitis of the cerebral vasculature, metastatic infection, and septicemia. Untreated LS can be rapidly fatal. Thrombus within the cerebral vasculature can have devastating neurological effects. Advances in antibacterial therapy have resulted in a global decline in the incidence of LS, and clinicians may not consider LS early in the disease process. Although the mortality of LS has declined, the morbidity associated with the disease has increased, particularly the neurological sequelae. OBJECTIVES: This report will provide readers with a better understanding of the etiology, clinical presentation, evaluation methods, and appropriate treatment of LS. CASE REPORT: We present an atypical case of LS secondary to community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infection progressing to bilateral cavernous sinus and ophthalmic vein thromboses with resultant binocular vision loss secondary to optic nerve and retinal ischemia. CONCLUSION: This case highlights the importance of early recognition of LS in the setting of a community-acquired MRSA infection as the unifying condition in a young patient with multiple acute neurologic impairments.

Septic cavernous sinus thrombosis with diffuse spread leading to cerebral ischemia.

INTRODUCTION: Septic cavernous sinus thrombosis (CST) is a rare disease with many etiologies and a diffuse array of initial presentation leading to high mortality. CASE: A 25-year-old male with a history of a nasal furuncle presents with an acute onset of fixed and dilated pupils, bilateral exophthalmos, hemorrhagic chemosis, elevated intraocular pressures, restricted extraocular motility, and unresponsiveness. A retinal septic emboli in the left eye is present on dilated fundoscopic exam while an exudative retinal detachment is present in the right eye. MRI/MRV revealed extensive thrombosis of cavernous sinuses, distal sigmoid dural sinuses, and proximal internal jugular veins with associated cerebral edema and multifocal areas of venous infarction. Blood cultures grew Methicillin-resistant Staphylococcus aureus and the patient suffered multi-system organ failure. Despite treatment with full dose systemic anticoagulation and broad spectrum antibiotics the patient suffered a cardiopulmonary arrest and expired. COMMENT: The acuity of onset coupled with the multiple risk factors for septic cavernous sinus thrombosis in this patient led to a fulminant presentation of this disease and ultimate poor outcome.

A case of Lemierre's syndrome causing panhypopituitarism, cavernous sinus thrombosis, ischaemic stroke and pulmonary embolism.

Infection is a rare cause of panhypopituitarism and has not been reported in the context of Lemierre's syndrome. We present the case of a previously well 19-year-old man, who presented acutely unwell with meningitis and sepsis. Fusobacterium necrophorum was isolated from peripheral blood cultures and identified on cerebrospinal fluid with 16S rDNA Polymerase Chain Reaction (PCR). Imaging demonstrated internal jugular vein thrombosis with subsequent cavernous venous sinus thrombosis. Pituitary function tests were suggestive of panhypopituitarism. The patient was diagnosed with Lemierre's syndrome complicated by meningitis, cavernous sinus thrombosis, base of skull osteomyelitis, ischaemic stroke and panhypopituitarism. He was treated with 13 weeks of intravenous antibiotics followed by 3 weeks of oral amoxicillin, and anticoagulated with dalteparin then apixaban. His panhypopituitarism was managed with hydrocortisone, levothyroxine and desmopressin.

Cavernous sinus and jugular thromboses, base of skull osteomyelitis and cranial nerve palsies: catastrophic complications of sphenoid sinusitis.

Sphenoid sinusitis is a clinically important entity as it may be associated with catastrophic complications including cavernous sinus thrombosis (CST), cerebral abscess or infarction, meningitis, base of skull osteomyelitis and cranial nerve palsies. We report a case of occult sphenoid sinusitis presenting as Streptococcus intermedius bacteraemia, bilateral jugular vein and CST, cranial nerve palsy and base of skull osteomyelitis.

Septic cavernous sinus thrombosis presenting as acute cerebral infarction and aneurysmal subarachnoid hemorrhage: Case report.

RATIONALE: Septic cavernous sinus thrombosis (SCST) is a rare infectious thrombophlebitic disease. The infection often arises from the tissues surrounding the cavernous sinus as well as the cavernous sinus drainage. Early symptoms of SCST include fever, headache, proptosis, ptosis, bulbar conjunctival edema, and limited eye movement. The complications include venous sinus thrombosis, intracerebral abscess, and subdural empyema. Aneurysmal subarachnoid hemorrhage combined with acute cerebral infarction has not been reported. PATIENT CONCERNS: A 46-year-old man presented with visual impairment in his right eye and intermittent headache for 2 months. Ten days later, the patient developed a sudden loss of consciousness, coma, cardiac arrest, and respiratory arrest. The patient eventually died. DIAGNOSES: SCST, acute cerebral infarction, aneurysmal subarachnoid hemorrhage, anterior cerebral artery aneurysm. INTERVENTIONS: Antiplatelet and lipid-lowering therapy, antibiotic treatment, emergency aneurysm clipping, and decompressive craniectomy. OUTCOMES: The patient underwent emergency aneurysm clipping and decompressive craniectomy, and postoperative head computed tomography showed a massive cerebral infarction in the right cerebral hemisphere. The patient eventually died. LESSONS: We report a case of SCST mainly presenting as acute cerebral infarction and aneurysmal subarachnoid hemorrhage, with an acute onset and ultimately a poor prognosis. This complication is extremely rare and have not yet reported according existing literatures but can be life-threatening if not recognized and treated promptly. Early antibiotic administration and early sinus drainage may alter the patient's prognosis. By describing this unusual the case we hope to raise awareness of the need of early illness detection and treatment in order to avoid catastrophic consequences. It also exemplifies the mechanism of acute inflammatory disorders and aneurysm development.

Different causes and diverse outcomes of extremely rare septic cavernous sinus thrombosis complicated with internal carotid artery stenosis.

BACKGROUND: Cases of acute sphenoid sinusitis complicated by septic cavernous sinus (CS) thrombosis and internal carotid artery (ICA) stenosis are rarely reported. Different causative pathogens have been reported for this condition. We present two extremely rare and special cases with diverse clinical presentations and outcomes. Case 1 involved a female patient with less extensive sinusitis, but critical ICA occlusion. Case 2 involved a male patient with extensive pansinusitis, meningitis, cerebritis, and vasculitis due to fungal infection, but less stenosis of the ICA lumen. Both patients underwent surgical debridement and received broad-spectrum antibiotics. Additional anti-fungal medication was also administered in Case 2. However, outcomes differed considerably between cases. DISCUSSION: Case 1 recovered with minimal neurological deficits and had Glasgow Outcome Scale (GOS) and modified Rankin Scale (mRS) scores of 5 and 2, respectively; however, the Case 2 had GOS and mRS scores of 3 and 4, respectively. Although rare, septic CS thrombosis with ICA stenosis can lead to unexpected and severe neurological sequelae. Fungal infection can result in catastrophic complications and poorer prognosis. CONCLUSION: In addition to early detection, aggressive surgical debridement and adequate antimicrobial treatment are crucial to satisfactory outcomes in patients with septic CS thrombosis complicated with ICA stenosis.

Septic cavernous sinus thrombosis-Case series and review of the literature.

BACKGROUND AND PURPOSE: Septic cavernous sinus thrombosis (CST) is a rare, life-threatening disease with infectious thrombosis causing associated complications resulting in high morbidity and mortality. We report a series of CST patients with assessment of arterial and intracranial complications. METHODS: We used the radiology database from a large, academic tertiary care center to collect all patients treated with CST between 2002 and 2019. Patient demographics, source of infection, treatment course and outcomes were evaluated. A review of the recent literature was also performed for similar reported complications from CST. RESULTS: 14 patients with CST treated during this time period were assessed. Of the 14 patients, 1 patient died. 7 patients had unilateral narrowing of ICA while 3 patients had bilateral narrowing. The ICA narrowing was reversible in 10/12 patients and improvement but persistent narrowing in one patient. One patient had an infectious pseudo aneurysm that was treated by coiling. Extension of thrombosis to the transverse- sigmoid sinuses and internal jugular vein were seen in 3 patients. Three patients had subdural empyema which was treated surgically. CONCLUSION: The prognosis of CST has improved with advancement in treatment, but complications are not infrequent.

Diagnostic difficulties in a patient with multiple sclerosis who presents with cranial nerve palsies: an unusual complication of dental work.

A woman in her 60s with multiple sclerosis (MS) presented with right-sided ptosis, right sixth nerve palsy, right facial paraesthesia and signs of sepsis. She had a recent diagnosis of a dental abscess. Investigations revealed a right submasseter abscess leading to bacterial meningitis (Streptococcus intermedius) and a cavernous sinus thrombosis. She was managed in intensive care and underwent surgical drainage of the abscess. Anticoagulation for 6 months was planned. Cavernous sinus thrombosis is a very rare complication of a dental abscess, and even less frequently associated with submasseter abscesses. The case was complicated by a history of MS, to which the patient's symptoms and signs were initially attributed to. This case highlights the diagnostic pitfalls, and aims to enhance learning around similar cases. To the best of our knowledge, this is the first case report of a masseter/submasseter abscess leading to cavernous sinus thrombosis.

Coil embolization of cavernous sinus in patients with direct and dural arteriovenous fistula.

To determine technical success and acute complication rates after endovascular coil packing of the cavernous sinus. Nineteen patients presented with either direct (13) or dural (6) arteriovenous fistula (AVF) and were treated by means of coil embolization of the cavernous sinus. The aim of treatment was complete obliteration of the fistula. In a retrospective study, the degree of obliteration, regression of symptoms as well as complication rates were evaluated. Initial complete obliteration was achieved in 12 patients, subtotal occlusion of the sinus in 6 and incomplete packing with major residual fistula in 1 of the patients. Retreatment was successfully performed in two patients with early recurrence of AVF. Follow-up showed complete occlusion rates in 16 and subtotal obliteration in 3 patients. Chemosis and exophthalmus regressed rapidly in all affected patients. Persistence of cranial nerve deficits was observed in 11 cases. Postinterventional thrombosis of the ophthalmic vein was the only major acute complication (n = 2). Coil embolization of the cavernous sinus in cases with AVF is a complex procedure that is technically feasible and safe in the majority of cases. Adequate anticoagulation is recommended to avoid thrombembolic complications. Long-term outcome has to be determined by further studies.

Subcortical intracerebral hemorrhage caused by mucormycosis in a patient with a history of bone-marrow transplantation.

We report on a rare case of a patient with rhinocerebral mucormycosis that presented as intracerebral hemorrhage (ICH). A 54-year-old man who was immunosuppressed had ophthalmoplegia. Four days later, ICH developed in his left frontal lobe. The ICH was surgically removed totally. Pathology specimen surgically obtained from brain surface adjacent to hematoma cavity showed blood vessels filled with Mucor mycelium. Combined with surgical findings, venous occlusion by Mucor mycelium might be the cause of ICH in the patient.

Lethal sphenoid fungal sinusitis in an immunocompromised elderly patient.

Sphenoid fungal balls are rare and typically indolent lesions, unless superinfected by bacteria or invasive to adjacent neurovascular structures. If the identification or treatment of underlying complications is delayed in an immunocompromised patient, a catastrophic outcome may result. We report the case of an elderly female patient with poorly controlled diabetes mellitus suffering from sphenoid fungal sinusitis that is complicated by cavernous sinus thrombophlebitis and carotid artery stenosis. In spite of reasonable diagnosis and therapy, the patient's general condition deteriorated and she eventually died. The clinical presentation, diagnosis, and treatment strategy are discussed.
