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.

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.

Bilateral cavernous sinus and left dural sigmoid sinus thrombosis associated with extreme exertion: a case report / Trombose bilateral do seio cavernoso e do seio sigmoide esquerdo associada a exercício extremo: relato de caso

ABSTRACT Septic cavernous sinus thrombosis is a rare but often debilitating and potentially fatal disease. We describe a case of bilateral orbital cellulitis with rapidly progressing cavernous sinus thrombosis and left sigmoidal sinus thrombosis in an immunocompetent 20-year-old military man who had undergone intensive physical training. The patient presented with rapid painful swollen left eye for 2 days. The examination results were gross proptosis with total ophthalmoplegia. He was treated with intravenous antibiotics and corticosteroid. At 1 week, visual acuity improved to 20/20 OU, with a normal intraocular pressure. There was a significant improvement in proptosis. The ocular motility of the right eye was fully restored, with slight residual ophthalmoplegia in the left eye. There was no residual illness or recurrence of illness at 3 months' follow-up.

RESUMO A trombose séptica do seio cavernoso é uma condição rara, mas frequentemente debilitante e potencialmente fatal. Descrevemos um caso de celulite orbital bilateral com progressão rápida para trombose do seio cavernoso e trombose do seio sigmoide esquerdo, em um militar imunocompetente de 20 anos de idade que havia sido submetido a treinamento físico intenso. O paciente apresentou um inchaço rápido e doloroso no olho esquerdo por 2 dias. Os resultados do exame foram proptose macroscópica com oftalmoplegia total. Ele foi tratado com antibióticos intravenosos e costicosteróide. Em 1 semana, a acuidade visual melhorou para 20/20, com pressão intraocular normal. Houve uma melhora significativa na proptose. A motilidade ocular do olho direito foi totalmente restaurada, com leve oftalmoplegia residual no olho esquerdo. Não houve doença residual ou recorrência da doença após três meses de acompanhamento.

Trombosis del seno cavernoso derecho secundaria a rinosinusitis esfenoidal: reporte de caso / Right cavernous sinus thrombosis secondary to sphenoidal rhinosinusitis: case report

RESUMEN La rinosinusitis bacteriana aguda es la infección de la mucosa nasal y de senos paranasales, que se manifiesta con congestión nasal, rinorrea purulenta y fiebre, de curso generalmente autolimitado. La trombosis del seno cavernoso (TSC) es una complicación poco frecuente, que se asocia a compromiso del seno esfenoidal y etmoidal, manifestándose clínicamente con cefalea, fiebre, alteración de pares craneanos y síntomas oculares. Ante su sospecha el estudio imagenológico es fundamental. En estos exámenes se debe buscar un defecto de llene en el seno cavernoso comprometido. El tratamiento debe iniciarse de forma precoz y contempla: antibioticoterapia, drenaje quirúrgico del seno afectado y anticoagulación. Se presenta a un paciente pediátrico masculino con TSC derecha posterior a una rinosinusitis esfenoidal no tratada, que respondió favorablemente al tratamiento. Se describe la clínica y manejo de esta patología, que presenta alta morbimortalidad, y que puede disminuirse considerablemente con un tratamiento precoz y agresivo.

ABSTRACT Acute bacterial rhinosinusitis is the infection of the nasal and paranasal mucous membrane, with symptoms such as nasal congestion, purulent rhinorrhea and fever, usually self-limiting. Cavernous sinus thrombosis (CST) is a rare complication, which is associated with sphenoid and ethmoid sinus involvement, clinically manifest with headache, fever, cranial nerve involvement and ocular symptoms. When suspected, imaging studies will confirm the clinical impression. They will show abnormal flow parameters in the compromised cavernous sinus. The treatment has to start as soon as possible and consists in broad spectrum intravenous antibiotics, surgical drainage of the site of the infection and anticoagulation. We present a patient with a right CST secondary to a non-treated sphenoidal sinusitis, that responded favorably to treatment. The clinical and management of this pathology is described, which presents a high morbidity and mortality that can be reduced considerably with an early and aggressive treatment.

A Case of Septal Abscess and Sphenoid Sinusitis after Dental Implant / 대한이비인후과학회지

A nasal septal abscess results from the collection of purulent fluid between the cartilage of bony septum and overlying mucoperichondrium or mucoperiosteum. Unless early diagnosis and surgical treatment are performed, serious complications such as cavernous sinus thrombophlebitis, sepsis, and saddle nose may occur. We report a case of septal abscess and sphenoid sinusitis that occurred after dental implant. A 74-year-old female with diabetes and liver cirrhosis was referred to the hospital for management of rapidly aggravated perinasal pain, nasal obstruction, and headache. The patient had undergone dental implant in the right upper incisor area 6 days ago. A CT revealed septal abscess and bilateral sphenoid sinusitis. The patient was operated upon to drain septal abscess, and both sphenoid sinuses were opened widely.

Compromiso de seno cavernoso como presentación de cáncer anaplásico de tiroides / Cavernous sinus involvement as presentation of anaplastic thyroid cancer

Anaplastic thyroid cancer is an uncommon malignant tumor, usually fatal, primarily affecting older adults and doesn't have effective systemic therapy. The median survival is less than 6 months from diagnosis. Brain metastases are low frequency and reach 18 percent. We present the case of a patient with papillary carcinoma of the thyroid who takes an aggressive form, becoming anaplastic carcinoma, with involvement of the central nervous system (CNS) manifested by paralysis of the cranial nerve IV, which is rare clinical condition.

Cavernous sinus thrombosis following dental extraction: a rare case report and forgotten entity

Prior to the advent of efficacious antimicrobial agents, the mortality rate from cavernous sinus thrombosis (CST) was effectively 100%. There have been very few reports of CST associated with tooth extraction. A 40-year-old female presented to the emergency room with swelling over the right side of the face and history of extraction in the upper right region by an unregistered dental practitioner. The patient presented with diplopia, periorbital ecchymosis, and chemosis of the right eye. A computed tomography scan revealed venous dilatation of the right superior ophthalmic vein. The patient was immediately treated with incision and drainage, intravenous antibiotics, and heparin (low molecular weight). Unfortunately, the patient died two days after surgery due to complications from the disease. CST is a rare disease with a high mortality rate. Therefore, dental health education in rural areas, legal action against unregistered dental practitioners, early diagnosis, and aggressive antibiotic treatment can prevent future mortality resulting from CST.

Neurological Manifestations of Acute Posterior Multifocal Placoid Pigment Epitheliopathy

BACKGROUND AND PURPOSE: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is an immune-mediated chorioretinal disease that causes acute visual symptoms with characteristic ophthalmoscopic findings. Neurological complications are rarely reported in the literature. Here we report two new cases of APMPPE that presented with neurological manifestations, one of which was associated with peripheral neuropathy, which has not been described before. METHODS: A retrospective database review of all patients with a diagnosis of APMPPE was performed. Clinical, ophthalmological, and neurological data were analyzed, and only cases of APMPPE with neurological complications were included. A literature review of several databases was also performed, and previous case reports were reviewed and analyzed in detail. RESULTS: In total, 56 cases of APMPPE-associated neurological complications were included in the analyses: 54 from the literature and 2 from our own practice. The most common complication was cerebral vasculitis, which affected 28 patients (50%), followed by headaches in 15 patients (26.8%). The other complications include sixth-cranial-nerve palsy, transient hearing loss, meningoencephalitis, cavernous sinus thrombosis, and viral meningitis. CONCLUSIONS: This report adds to the literature of a novel association of APMPPE with peripheral neuropathy, and comprehensively reviews the neurological manifestations of this disease. A high level of suspicion should be applied when dealing with a case of APMPPE. We recommend applying detailed clinical neurological examinations and magnetic resonance imaging to APMPPE patients, and then early steroid treatment if the examination is positive or even suspicious. Early treatment with steroids and long-term treatment with immunosuppressive azathioprine with interval neurological evaluations will contribute positively to the outcomes and avoid fatal complications, namely strokes.

Trombosis de seno cavernoso causada por zigomicosis invasiva fulminante: A propósito de un caso / Cavernous sinus Thrombosis caused by fulminant invasive zygomycosis: A case report

Zygomycosis is an opportunistic fungal infection caused by fungi of the Mucorales order. It’s potentially lethal infection which generally affects diabetic or inmunocomprised patients. Cavernous sinus thrombosis is uncommon complication. We report the case of a 67 year old woman with invasive zycomycosis who present cranial nerves dysfunction (III, IV, VI, V1 and V2 branches of the trigeminal nerve), proptosis and retroorbital pain as initial manifestation. Brain magnetic resonance imaging evidence early indirect signs. Biopsy of the cavernous sinus revealed Rhizopus as the offending agent. A high index of suspicion is needed to correctly diagnose this condition for its optimal management.

La zigomicosis es una infección oportunista y potencialmente letal producida por hongos del orden Mucorales. Afecta a pacientes diabéticos e inmunocomprometidos. La trombosis del seno cavernoso es una complicación poco frecuente. Presentamos el caso de una paciente mujer de 67 años diagnosticada de zigomicosis invasiva que debutó con compromiso de pares craneales (III, IV, VI además de las ramas V1 y V2 del nervio trigémino), proptosis y dolor retroorbitario derecho. La resonancia magnética craneal, en fase aguda, mostró signos indirectos característicos. La biopsia de seno cavernoso confirmó la presencia de Rhizopus. Se precisa un alto índice de sospecha clínica que favorezca una intervención terapéutica precoz y agresiva.

Cavernous sinus thrombosis progression from trismus

In the Department of Oral and Maxillofacial Surgery, patients with trismus can be easily identified. If the cause of trismus is infection of the masticatory space near the pterygoid plexus, the possibility of cavernous sinus thrombosis should be considered. We report the case of a patient who presented with limited mouth opening and progressed to cavernous sinus thrombosis, along with a review of the relevant literature.

Trombose parcial do seio cavernoso / Cavernous sinus thrombosis

A trombose do seio cavernoso (TSC) é uma situação clínica rara, resultando normalmente da complicação de um processo infeccioso dos seios paranasais. Outras causas incluem alterações pró-trombóticas, anemia e trauma. Os sinais e sintomas são extremamente variados e inespecíficos, sendo o seu diagnóstico efetuado através de ressonância magnética nuclear (RMN). Os autores apresentam um caso clínico de uma doente com 75 anos de idade, que recorre ao serviço de urgência devido à dor em olho direito vermelho associado à cefaléias frontais com quatro dias de evolução. Ao exame oftalmológico observou-se defeito pupilar aferente relativo no olho direito (OD); na biomicroscopia vasos episclerais dilatados, catarata nuclear e à fundoscopia um edema discreto da papila com apagamento do rebordo nasal, hemorragias punctiformes dispersas e tortuosidade vascular em OD. A realização de angio-RMN confirmou o diagnóstico tendo a doente sido tratada com enoxaparina. Apesar do tratamento da TSC ser um tratamento etiológico, foi demonstrado que a anticoagulação está associada à diminuição da taxa de mortalidade.

Cavernous sinus thrombosis (CST) is a rare condition, usually results from a late complication of an infection of the paranasal sinuses. Other causes include prothrombotic disorders, anemia and trauma. The signs and symptoms are extremely varied and nonspecific, being the diagnosis made through magnetic resonance imaging (MRI). The authors present a 75-year-old woman, admitted in the emergency room complaining of ocular pain in the right eye (RE), red eye and frontal headache. She presented on ophthalmic examination of the RE: dilated episcleral vessels, nuclear cataract and a relative afferent pupillary defect. Fundoscopy examination of the RE revealed disc edema with nasal disc margin blurred, small dot hemorrhages and vascular tortuosity. The MRI angiography confirmed the diagnosis and the patient was treated with low molecular weight heparin. Despite treatment of CST is directed to the causal situation, being shown that anticoagulation is associated with reduction in mortality.

Infecção orbitária: experiência no manejo de seis casos / Orbital infeccion: experience on the management of six cases

Infecções orbitárias são enfermidades, que requerem atenção e cuidados especiais. Os principais fatores etiológicos associados são sinusites paranasais e o trauma local. Essas infecções classificam-se em pré-septal e pós-septal e distinguem-se clinicamente, de acordo com a manutenção da acuidade visual e motilidade do globo ocular. O curso da infecção pode agravar com disfunção da motilidade ocular extrínseca, perda de visão e trombose do seio cavernoso. A tomografia computadorizada (TC) é o principal exame imaginológico para a classificação do abscesso, investigação etiológica, determinação da gravidade e a relação do processo com o sistema nervoso central. Este trabalho apresenta e discute o manejo de seis pacientes admitidos com infecção orbitária pelo serviço de Cirurgia e Traumatologia Bucomaxilofacial do Hospital Geral Roberto Santos e em Salvador, Bahia. A TC mostrou não haver disseminação do processo inflamatório para o sistema nervoso central em nenhum dos casos tendo esse achado sido fundamental para determinar que a conduta estivesse restrita à drenagem, sem necessidade de craniotomia. As intervenções cirúrgicas e a antibioticoterapia estavam indicadas devido à importante congestão tecidual e intensa sintomatologia dolorosa. Todos os pacientes apresentaram remissão da infecção e acuidade visual preservada... (AU)

Orbital infections are diseases that require special attention and care. The main risk factors are associated with paranasal sinusitis and local trauma. These infections are classified into pre-septal and post-septal and distinguished clinically according to the maintenance of visual acuity and eye motility. The course of the infection may worsen with extrinsic ocular motility dysfunction, loss of vision and cavernous sinus thrombosis. Computed tomography (CT) is the primary imaging examination for the classification of the abscess, etiologic investigation, determining the severity of the process and the relationship with the central nervous system. This paper presents and discusses the management of six patients admitted with orbital infection by service Oral and Maxillofacial Surgery General Hospital Roberto Santos in Salvador, Bahia. A CT scan showed no spread of the inflammatory process in the central nervous system and in any case this finding was important to determine that the drainage duct was confined without requiring craniotomy. Surgical interventions and antibiotics were given because of the important tissue congestion and intense painful symptoms. All patients had remission of infection and preserved visual acuity... (AU)

Cavernous sinus thrombosis caused by a dental infection: a case report

Cavernous sinus thrombosis not only presents with constitutional symptoms including fever, pain and swelling but also with specific findings such as proptosis, chemosis, periorbital swelling, and cranial nerve palsies. It is known to occur secondary to the spread of paranasal sinus infections in the nose, ethmoidal and sphenoidal sinuses. However, paranasal sinus infection of dental origin is rare. The following is a case of cavernous sinus thrombosis due to the spread of an abscess in the buccal and pterygomandibular spaces via buccal mucosal laceration.
