Concomitant rapidly growing aneurysm of intracavernous carotid artery and cavernous sinus thrombosis: Case report and review of the literature.

RATIONALE: Intracavernous infectious aneurysm (ICIA), represents a rare entity that is always described in the form of case reports in the literature. The coexistence of ICIA and cavernous sinus thrombosis (CST) is extremely rare and poorly understood. PATIENT CONCERNS: A 53-year-old female patient presented to our hospital with headache, nausea and fatigue for 3 weeks. She complained of blurry vision and drooping eyelids before admission. Neurological examination revealed bilateral decreased visual acuity, limitation of extraocular movements and decreased sensation of forehead. Brain magnetic resonance imaging (MRI) showed mixed signal intensities in both cavernous sinuses and expansion of right superior ophthalmic vein, suggesting the formation of CST. One month later, computed tomography angiography (CTA) confirmed a large aneurysm was attached to the left intracavernous carotid artery (ICCA). DIAGNOESE: This patient was diagnosed with ICIA and CST. INTERVENTIONS: She was administered with intravenous meropenem and vancomycin and subcutaneous injection of low molecular heparin for 4 weeks. OUTCOMES: One month later, her extraocular movement had significantly improved, without ptosis and conjunctival congestion. At 1-year follow-up, her ophthalmoplegia fully recovered. Fortunately, such large aneurysm did not rupture in spite of slight broadening. LESSONS: The coexistence of ICIA and CST is extremely rare. Contiguous infection from adjacent tissues is the foremost cause of ICIA. A repeated angiographic examination is recommended under enough anti-infective treatment due to the characteristics of rapid emergence and fast growth of infectious aneurysms.

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.

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.

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.

Cavernous sinus thrombosis with bilateral orbital vein involvement and diffuse ischemic retinopathy / Trombose do seio cavernoso com envolvimento bilateral das veias orbitais e retinopatia isquêmica difusa

ABSTRACT A 53-year-old man with a 3-day history of periorbital swelling and vision loss in the left eye was found to have septic cavernous sinus thrombosis with bilateral orbital vein involvement causing congestive orbitopathy. He was treated with an emergent canthotomy and cantholysis, intraocular pressure-lowering drops, antibiotics, anticoagulation, and serial examinations. Optical coherence tomography ultimately revealed diffuse ischemic destruction of both layers of the retina, which suggested occlusion of the ophthalmic artery or the short posterior ciliary arteries and central retinal artery without intracavernous internal carotid artery involvement. The patient remained without light perception in the left eye after treatment.

RESUMO Um homem de 53 anos, com história de 3 dias de edema periorbital e perda de visão no olho esquerdo, apresentou trombose séptica do seio cavernoso com envolvimento bilateral das veias orbitais, causando uma orbitopatia congestiva. O paciente foi tratado com uma cantotomia e cantólise de emergência, colírios para redução da pressão intraocular, antibióticos, anticoagulantes e exames seriados. A tomografia de coerência óptica finalmente demonstrou destruição isquêmica difusa de ambas as camadas da retina, sugerindo uma oclusão da artéria oftálmica ou das artérias ciliares posteriores curtas e da artéria retiniana central, com ausência de envolvimento do segmento intracavernoso da artéria carótida interna. O paciente permaneceu sem percepção luminosa no olho esquerdo.

Orbital cellulitis and cavernous sinus thrombosis with contralateral sinus disease in a COVID-19 positive adolescent patient.

Patients with COVID-19 have been reported to have elevated coagulation factors, which is a well-documented cause of venous thromboembolism events such as deep vein thrombosis and pulmonary embolism. Other venous thrombotic events, however, such as cavernous sinus thrombosis (CST) have been less commonly observed, specifically in combination with primary orbital cellulitis. Due to its unique anatomic location, the cavernous sinus is susceptible to thrombophlebitis processes including septic thrombosis and thrombosis most commonly from sinusitis. Many studies have shown that in the antibiotic era thromboembolic events of the cavernous sinus are less common due to infection spread from the orbit or facial region. This case report describes a 17-year-old COVID-19 positive male who presented with a left-sided primary orbital cellulitis with CST without radiographic evidence of ipsilateral sinus disease.

Superior ophthalmic vein and cavernous sinus thrombosis associated with COVID-19: a case report / Trombose de veia oftálmica superior e seio cavernoso associada à COVID-19: relato de caso

ABSTRACT Cavernous sinus and superior ophthalmic vein thrombosis is a rare clinical condition, and little described in the literature. The clinical presentation is nonspecific and highly variable, and symptoms may include red eye, ophthalmoplegia, coma, and death. The main etiology results from infection of the paranasal sinuses. The final diagnosis must be made through imaging tests such as magnetic resonance imaging. We describe a case of cavernous sinus and superior ophthalmic vein thrombosis after COVID-19 infection in a 64-year-old patient with persistent ocular hyperemia and pain on eye movement. Ophthalmological examination showed preserved visual acuity, conjunctival hyperemia, dilation of episcleral vessels and retinal vascular tortuosity in the right eye. Magnetic resonance imaging confirmed the diagnosis. The association with the COVID-19 was raised, excluding other infectious causes. Enoxaparin and Warfarin were started with significant improvement in the ocular clinical presentation and maintenance of initial visual acuity after 12 months of follow-up.

RESUMO A trombose de seio cavernoso e veia oftálmica superior é uma condição clínica rara e pouco descrita na literatura. A apresentação clínica é inespecífica e altamente variável. Os sintomas podem incluir olho vermelho, oftalmoplegia, coma e morte. A etiologia principal resulta da infecção dos seios paranasais. O diagnóstico final deve ser efetuado por meio de exames de imagem, como ressonância magnética. Descrevemos um caso de trombose de seio cavernoso e veia oftálmica superior após COVID-19 em paciente de 64 anos e com quadro de hiperemia ocular persistente e dor à movimentação ocular. Ao exame oftalmológico, observou-se acuidade visual preservada, hiperemia conjuntival, dilatação de vasos episclerais e tortuosidade vascular retiniana em olho direito. A ressonância confirmou o diagnóstico. A associação com a COVID-19 foi levantada, excluindo-se demais causas infecciosas. Prescrevemos enoxaparina e varfarina, com melhora do quadro clínico ocular e manutenção da acuidade visual inicial após 12 meses de acompanhamento.

Septic cavernous sinus thrombosis after minor head trauma: A case report.

RATIONALE: Septic cavernous sinus thrombosis (SCST) is a rare but life-threatening condition that commonly arises from infections, including paranasal sinusitis, otitis media, and skin infection. Meanwhile, head trauma as a predisposing factor of SCST has been scarcely reported. We report a case of SCST complicated by meningitis after minor head trauma, even in the absence of identifiable fractures. PATIENT CONCERNS AND DIAGNOSIS: A 77-year-old female presented with diplopia combined with ocular pain and headache lasting a week. She had a recent blunt head trauma 2 weeks before the diplopia onset. The trauma was not accompanied by identifiable skull fractures, bleeding, or loss of consciousness. Neurological examination revealed incomplete ptosis, eyelid swelling, and medial and vertical gaze limitations of both eyes. Gadolinium-enhanced brain magnetic resonance imaging demonstrated multifocal thrombotic filling defects, including those of the cavernous sinus, sinusitis involving the sphenoid and ethmoid sinuses, and otomastoiditis. The cerebrospinal fluid assay result was compatible with bacterial meningitis. A tentative diagnosis of SCST complicated by bacterial meningitis and multifocal cerebral venous thrombosis was made based on clinical, laboratory, and neuroradiologic findings. INTERVENTION: Intravenous triple antibiotic therapy (vancomycin, ceftriaxone, and ampicillin) for 2 weeks combined with methylprednisolone (1 g/d for 5 days) was administered. Despite the initial treatment, carotid-cavernous fistula was newly developed during hospitalization. Therefore, coil embolization was performed successfully for the treatment of carotid-cavernous fistula. OUTCOMES: The symptoms of the patient including diplopia gradually improved during the 8-month follow-up period. LESSONS: Minor head trauma is a rare but possible cause of SCST. Early recognition and prompt treatment are essential for improving outcomes. Moreover, close observation is warranted, even if apparent serious complications were absent during initial evaluations in minor head trauma.

Methamphetamine Injection Into Face Causing Fatal Cavernous Sinus Thrombosis.

ABSTRACT: Cavernous sinus thrombosis is a rare and often fatal condition, usually associated with infections in the head and neck region. Clinical presentation includes fever, headache, and periorbital swelling. Mortality can be high; however, prompt treatment can reduce the probability of death. We present a case of a cavernous sinus thrombosis associated with methamphetamine injection into the face.

Clinical Profile and Long-Term Outcomes in Pediatric Cavernous Sinus Thrombosis.

BACKGROUND: Pediatric cavernous sinus thrombosis (CST) is a rare condition with limited data regarding its clinical characteristics and long-term outcomes. The objective of this study was to describe the clinical and radiologic features, diagnostic evaluation, management, and long-term prognosis and to identify clinical variables associated with long-term outcomes in pediatric CST. METHODS: A retrospective chart review of patients younger than 18 years diagnosed with a CST between 2004 and 2018 at a single center was conducted. RESULTS: We identified 16 (M:F = 10:6) children with CST with a mean age of 7.6 years (10 days to 15 years) and average follow-up duration of 29 months (3 weeks to 144 months). The most common symptom and examination finding at presentation was eyelid swelling (n = 8). Six patients had bilateral CST. The most common etiologies were sinusitis (n = 5) and orbital cellulitis (n = 5). Treatments included antibiotics (n = 14), anticoagulation (n = 11), and surgery (n = 5). Only one patient died due to intracranial complications. Twelve patients had a normal examination at follow-up. None of the clinical variables including age (P = 0.14), gender (P = 0.09), use of antibiotics (P = 1.00) or anticoagulation (P = 1.00), surgery (P = 0.28), parenchymal abnormalities (P = 0.30), additional cerebral venous thrombosis (P = 0.28), and early versus late commencing of anticoagulation (P = 1.00) were significant when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging. CONCLUSIONS: Our study is one of the largest cohorts with the longest follow-up data for the pediatric CST. Most of our patients had favorable outcomes at follow-up. We found no statistical difference between clinical variables when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging.

Cavernous sinus thrombosis followed by brain ischaemia in a type-1 diabetic patient: a persistent endodontic infection report.

Central nervous system infections and cavernous sinus thrombosis are associated with high mortality rates and may be a consequence of oral infection propagation. A 24-year-old woman has attended a private dental office with a pain complaint in the upper right central incisor and had the endodontic treatment completed. However, the patient returned to the dental office reporting pain in the same tooth and the presence of swelling. Then, the root canal was retreated. After one week, the patient presented to a Basic Health Unit with a history of vomiting and convulsion crisis followed by loss of consciousness. A computed tomography exam showed cavernous sinus thrombosis and brain ischaemic areas. The present report describes a rare case of cavernous sinus thrombosis followed by brain ischaemia in a type-1 diabetic patient, associated with persistent endodontic infection, with subsequent patient's death.

Imaging features of rhinocerebral mucormycosis: from onset to vascular complications.

Rhinocerebral mucormycosis (RCM) may result in severe intracranial ischemic and hemorrhagic lesions. Both computed tomography (CT) and magnetic resonance imaging (MRI) play an essential role in the diagnosis of RCM, but whereas CT is better for assessing bone erosion, MRI is superior in evaluating soft tissue, intraorbital extension, and in assessing intracranial and vascular invasion. Specific CT and MRI techniques, such as CT angiography or enhanced MR angiography, and more advanced MRI sequences such as gadolinium-3D Black Blood imaging, contribute to the assessment of the extension of vascular invasion.In this pictorial review, we describe specific CT and MRI signs of RCM, mainly focusing on its life-threatening complications due to vascular involvement.
