Isolated pupillary-sparing cranial nerve III palsy from a subgaleal abscess

@#Cranial nerve (CN) III palsy is rarely caused by intraorbital compression, let alone from a subgaleal abscess. We present a case of a hypertensive 55-year-old man with an acute isolated pupillary-sparing left CN III palsy from a left subgaleal abscess with associated pterional osteomyelitis and frontotemporal mass. This is the first reported such case and the third reported case of a chronic spontaneous subgaleal abscess. A seemingly routine case of an acute, pupillary-sparing, isolated CN III palsy from hypertension turned out to be a rare case in terms of etiology of the palsy and of the source of the abscess.

Síndrome de Tolosa-Hunt una extraña causa de oftalmoplejía dolorosa: reporte de caso / Tolosa-Hunt syndrome a strange cause of painful ophthalmoplegia: case report

RESUMEN INTRODUCCIÓN: El síndrome de Tolosa-Hunt (STH) se caracteriza por una oftalmoplejía dolorosa, de etiología desconocida. De acuerdo con los hallazgos histopatológicos, se ha descrito la formación de un tejido granulomatoso en los senos cavernosos. PRESENTACIÓN DEL CASO: Una mujer de 22 años con cuadro clínico de 3 semanas de evolución caracterizado por cefalea hemicránea derecha, dolor ocular derecho y diplopía. Su examen físico evidenció la existencia de una oftalmoplejía derecha; la resonancia magnética (RM) de silla turca demostró engrosamiento y realce en la región del seno cavernoso derecho. Se presenta el caso clínico de una causa inusual de oftalmoplejía dolorosa. DISCUSIÓN: La oftalmoplejía dolorosa tiene múltiples diagnósticos diferenciales que incluyen causas neoplá-sicas, vasculares, inflamatorias e infecciosas que pueden afectar el seno cavernoso o la fisura orbitaria superior. El STH, que es una causa rara de oftalmoplejía dolorosa, sigue siendo un diagnóstico de exclusión. Por otra parte, se caracteriza por tener una adecuada respuesta al tratamiento con glucocorticoides. CONCLUSIÓN: La negatividad en las investigaciones de las etiologías de oftalmoplejía, los hallazgos imagenológicos en la RM y la adecuada respuesta cínica con el uso de los corticoides permiten confirmar el diagnóstico. No debería ser necesaria la biopsia del seno cavernoso ante la sospecha de STH con adecuada respuesta al manejo corticoide.

ABSTRACT INTRODUCTION: Tolosa-Hunt syndrome (THS) is characterized by painful ophthalmoplegia of unknown etiology, the formation of a granulomatous tissue in the cavernous sinuses has been described in histopatho-logical findings. CASE PRESENTATION: A 22-year-old woman presenting with 3 weeks of right sided headache, right eye pain and diplopia. Physical examination revealed the existence of a right ophthalmoplegia; magnetic resonance imaging (MRI) of the sella turcica showed thickening and enhancement of the right cavernous sinus. A clinical case of an unusual cause of painful ophthalmoplegia is presented. DISCUSSION: Painful ophthalmoplegia has multiple differential diagnoses that include neoplastic, vascular, inflammatory and infectious causes that can affect the cavernous sinus or the superior orbital fissure. STH is a rare case of painful ophthalmoplegia that continues to be a diagnosis of exclusion characterized by an adequate response to treatment with glucocorticoids. CONCLUSION: The negativity of the investigations for the causes of ophthalmoplegia, the imaging findings in the MRI and the adequate response to corticosteroids allows the diagnosis to be made. Biopsy should not be necessary when THS is suspected and there is an adequate response to corticosteroid management.

Fibrosis congénita de los músculos extraoculares / Congenital Fibrosis of Extraocular Muscles

La fibrosis congénita de los músculos extraoculares se caracteriza por una oftalmoplejía externa congénita, no progresiva, generalmente bilateral, con ptosis y alteración de los movimientos oculares. Existen varios tipos en dependencia del gen afectado y puede estar acompañada de hallazgos adicionales tanto oculares como generales. Para el manejo de los casos se realiza cirugía de la ptosis, alineación ocular y corrección del torticolis, además de su corrección óptica y rehabilitación para maximizar el resultado visual. Con el objetivo de estar al día sobre esta enfermedad se realiza una revisión de las publicaciones de los últimos cinco años en este tema. Actualmente no hay tratamientos que puedan restaurar la funcionalidad completa y el rango de movimiento de los músculos extraoculares, pero mejorar su funcionalidad visual es primordial(AU)

Congenital fibrosis of the extraocular muscles is characterized by congenital external ophthalmoplegia, nonprogressive, usually bilateral, with ptosis and altered eye movements. There are several types depending on the affected gene and it may be accompanied by additional ocular or general findings. For the management of these cases, ptosis surgery, ocular alignment and torticollis correction are performed, as well as optical correction and rehabilitation to maximize visual outcome. In order to be updated about this disease, a review of the publications on this subject within the last five years is carried out. Currently, there are no treatments that can restore full functionality and range of motion of the extraocular muscles, but improving their visual functionality is paramount(AU)

YANG Jun's clinical experience of acupuncture for oculomotor paralysis / 中国针灸

Professor YANG Jun's clinical experience of acupuncture and moxibustion for oculomotor paralysis is summarized. Professor YANG Jun pays attention to disease differentiation and syndrome differentiation in the treatment of this disease. According to the characteristics of oculomotor paralysis, "early diagnosis and seeking treatment from the source" is advocated. According to the etiology and pathogenesis, professor YANG divides oculomotor paralysis into three types: the syndrome of wind-evil attacking collaterals, the syndrome of spleen-stomach weakness and the syndrome of qi-deficiency and blood-stasis. As such, the acupoints are selected according to syndrome differentiation, and several different acupuncture methods (pricking needling at eyelids, penetrating needling and lifting eyelids and contralateral- balance needling on the healthy side) are adopted to improve the symptoms of oculomotor paralysis. It is also suggested to use the combination of scalp acupuncture and electroacupuncture to achieve the best dose-effect state. Moreover, local stimulation around the eyes is important to achieve the effects of "qi reaching affected area".

Síndrome de Miller Fisher, un desafío diagnóstico de oftalmoplejía: reporte de un caso / Miller Fisher syndrome, a diagnostic challenge of ophthalmoplegia: a case report

El síndrome de Guillain-Barré (SGB), y sus derivados, entre ellos el síndrome de Miller Fisher (SMF); junto a otras patologías de origen neurológico como la Polineuropatía desmielinizante inflamatoria crónica (CIDP), las polineuropatías de causa metabólica, miastenia gravis, esclerosis lateral amiotrófica (ELA), síndrome de Lambert-Eaton, encefalopatía de Wernicke entre otras; presentan signos y síntomas neurológicos de presentación común. De este modo, la importancia del examen neurológico acabado; y los exámenes de apoyo diagnóstico como: laboratorio -destacando el líquido cefalorraquídeo (LCR)-, electromiografía, y toma de imágenes, son cruciales para esclarecer el diagnóstico. Así, es posible ofrecer un tratamiento de forma precoz, basado en la evidencia, y con el objetivo de disminuir la letalidad de la enfermedad. En el presente texto se plasma un subgrupo de patología de SGB, el SMF, el cual posee una incidencia significativamente baja, una clínica característica, y un pronóstico bastante ominoso sin un tratamiento adecuado. En el presente texto se plasma el reporte de un caso abordado en el Hospital San Pablo de Coquimbo, Chile.

Guillain-Barré syndrome (GBS) and its derivatives, including Miller Fisher syndrome (MFS), along others pathologies of neurological origin such as chronic inflammatory demyelinating polyneuropathy (CIDP), metabolic polyneuropathies, myasthenia gravis, amyotrophic lateral sclerosis (ALS), Lambert-Eaton syndrome, Wernicke's encephalopathy and well as others, have common neurological signs and symptoms. In this way, the importance of a thorough neurological examination, and supporting diagnostic tests such as: laboratory, -cerebrospinal fluid (CSF)-electromyography, and imaging, are crucial to clarify the diagnosis. Thus, it is possible to offer early, evidence-based treatment with an aim of reducing the disease's lethality. In the text below we present a subgroup of GBS pathology, MFS, which has a significantly low incidence, a characteristic clinical picture, and a rather ominous prognosis without adequate treatment. In the following text/paper is shown the report of a case approached in San Pablo Hospital, from Coquimbo, Chile.

Manifestações oftalmológicas em paciente com aneurisma gigante de carótida interna / Ophthalmological manifestation in patient with gigantic aneurysm of the internal carotid

RESUMO Os aneurismas intracranianos são dilatações em segmentos arteriais que irrigam o sistema nervoso central. Acometem 2% da população e as alterações oftalmológicas podem ser as primeiras manifestações do quadro. O objetivo deste relato foi descrever um caso de aneurisma de artéria carótida interna que cursou com restrição da movimentação ocular, alteração do reflexo fotomotor, ptose palpebral, dor facial e cervical. O diagnóstico foi confirmado pela identificação do aneurisma por meio do exame de angiografia cerebral. Foi realizado teste de oclusão por balão, cujo resultado positivo possibilitou a oclusão total da artéria carótida interna por meio de ligadura cirúrgica, procedimento este realizado com sucesso.

ABSTRACT Intracranial aneurysms are dilations in segments of the arteries that irrigate the central nervous system. They affect 2% of the population and the ophthalmologic disorders may be the first evidence in the clinical examination. The aim of the report is to describe a case of an internal carotid artery aneurysm that showed restrictions of ocular movements, change of pupillary light reflex, palpebral ptosis, facial, and cervical pain. This diagnosis was confirmed by the identification of the aneurysm through angiography. A balloon occlusion test was performed, and its positive result made a complete occlusion of the Internal Carotid Artery possible through surgery ligation, procedure that was successful.

Complex strabismus: a case report of hypoplasia of the third cranial nerve with an unusual clinical presentation / Estrabismo complexo: um caso relacionado à hipoplasia do terceiro nervo craniano com apresentação clínica incomum

ABSTRACT Congenital cranial dysinnervation disorders are a group of complex strabismus syndromes that present as congenital and non-progressive ophthalmoplegia. The genetic defects are associated with aberrant axonal targeting onto the motoneurons, development of motoneurons, and axonal targeting onto the extraocular muscles. We describe here the surgical management of a 16-year-old boy who presented with complex strabismus secondary to hypoplasia of the third cranial nerve and aberrant innervation of the upper ipsilateral eyelid.

RESUMO Os distúrbios de inervação craniana congênita en­globam um grupo de síndromes associadas a estrabismos complexos, que se apresentam como oftalmoplegia congênita e não progressiva e são frequentemente herdadas. Os defeitos dos genes estão associados a erros no desenvolvimento ou direcionamento axonal dos motoneurônios, e erros no direcionamento axonal para os músculos extraoculares. Este caso descreve o caso de um menino que apresenta estrabismo complexo secundário à hipoplasia do terceiro nervo craniano e inervação aberrante da pálpebra superior ipsilateral, bem como o resultado após a correção cirúrgica.

Total remission of Tolosa-Hunt Syndrome with single-dose of infliximab / Remissão total da Síndrome de Tolosa-Hunt com dose única de infliximabe

Abstract Tolosa-Hunt syndrome is a painful ophthalmoplegia caused by non-specific granulomatous inflammation, corticoid-sensitive, of the cavernous sinus. The etiology is unknown. Recurrences are common. The diagnosis is made by exclusion, and a variety of other diseases involving the orbital apex, superior orbital fissure and cavernous sinus should be ruled out. This study reports a case of a 29-year-old woman, diagnosed with Tolosa-Hunt Syndrome, who presented ophthalmoparesis and orbital pain. She had poor response to corticotherapy and developed colateral effects, so she was treated with single infliximab dose immunosuppression, evolving total remission of the disease.

Resumo A Síndrome de Tolosa-Hunt é uma oftalmoplegia dolorosa causada por uma inflamação granulomatosa não específica, sensível a corticoides, do seio cavernoso. A etiologia é desconhecida. Recorrências são comuns. O diagnóstico é feito por exclusão, devendo ser descartada uma variedade de outras doenças que envolvem o ápice orbitário, fissura orbitária superior e seio cavernoso. O presente estudo trata-se de um relato de caso de uma paciente de 29 anos, diagnosticada com Síndrome de Tolosa-Hunt, que apresentou paresia e dor em região orbital. Obteve resposta pouco efetiva a corticoterapia e desenvolveu efeitos colaterais, por isso foi tratada com dose única de infliximabe, evoluindo com remissão total da doença.

Etiology, localization of the lesion, and prognosis for patients firstly diagnosed in ophthalmology department with oculomotor nerve palsy / 中南大学学报(医学版)

OBJECTIVES@#Oculomotor nerve palsy is a kind of disease with many causes, showing eye movement disorders, abnormal eyelid position, and/or damage of the pupil. The etiology of oculomotor nerve palsy in different departments is different. The study discussed the etiology, localization of the lesion, and prognosis for oculomotor nerve palsy firstly diagnosed in department of ophthalmology.@*METHODS@#Clinical data of 137 hospitalized patients with oculomotor nerve palsy at the Department of Ophthalmology, the First Medical Center of PLA General Hospital from 2009 to 2018 were retrospectively collected. The etiology and its distribution characteristics in different age groups, the location of the lesion, and the prognosis of patients were analyzed.@*RESULTS@#In 137 patients, the top 3 causes for oculomotor nerve palsy were head trauma (38.69%), cavernous sinus lesions (12.40%), and orbital inflammation (9.49%). Other causes included intracranial aneurysm, the intracranial space-occupying lesion, cerebral vessel diseases, infection, orbital tumors, diabetes, the operation of nasal cavity. Traumatic oculomotor nerve palsy was more common in young adults aged 20-49 years and in the patients with cerebral vascular disease in elderly people aged 60-69 years, while diabetic oculomotor nerve palsy is common in middle-aged and elderly people aged 50-69 years. The age distribution of other etiological types was relatively balanced. Seventy-five cases of orbital apex lesions were due to trauma, inflammation, infection, and tumor; 40 cases of cavernous sinus lesions were due to inflammation, tumor, and thrombosis; 6 cases of subarachnoid lesions were due to aneurysms, tumors, and trauma; 5 cases were oculomotor nucleus lesions were due to infarction; 11 cases could not be allocated because of unknown etiology. After treatment, the corrected visual acuity of oculomotor nerve palsy side was not significantly improved. The patients with oculomotor nerve palsy caused by intracranial aneurysm, cerebrovascular disease, and diabetes mellitus had the highest proportion of partial or complete recovery from ptosis and ocular dyskinesia.@*CONCLUSIONS@#Oculomotor nerve palsy is a common cause of ophthalmoplegia and diplopia. Head trauma, cavernous sinus lesions, and orbital inflammation are the most common causes for oculomotor nerve palsy first diagnosed in ophthalmology department. Traumatic oculomotor nerve palsy is common in adolescents. Oculomotor nerve palsy caused by diabetes and cerebrovascular disease are common in the middle-aged and elderly people. Most of the lesions locate in the orbital apex and cavernous sinus. The prognosis of corrected visual acuity is poor. The prognosis of ptosis and ocular dyskinesia caused by intracranial aneurysm, cerebrovascular disease, and diabetes is good. Figuring out the cause timely and accurately is the basis and key to treat oculomotor nerve palsy.

Síndrome de Tolosa-Hunt, uma oftalmoplegia dolorosa / Tolosa Hunt Syndrome, a painful ophthalmoplegia

Resumo A síndrome de Tolosa-Hunt (STH) é uma doença rara caracterizada por oftalmoplegia dolorosa unilateral de início súbito causada por uma inflamação granulomatosa inespecífica no seio cavernoso ou fissura orbital superior (ou ambos). A oftalmoparesia ocorre quando os nervos cranianos III, IV e VI são acometidos pela inflamação. Disfunções pupilares podem estar presentes e está relacionado com acometimento das fibras simpáticas que passam pelo seio cavernoso na porção da artéria carótida interna ou fibras parassimpáticas ao redor do nervo oculomotor. O acometimento do primeiro ramo do trigêmeo pode provocar parestesia território correspondente à distribuição desde ramo (testa). Raramente, pode haver extensão da inflamação para além do seio cavernoso ou fissura orbital superior podendo acometer também o nervo óptico. Há uma boa resposta com o uso de corticoides e pode haver remissões espontâneas. Recidivas ocorrem em 40% dos casos. A doença é mais comum após a segunda década de vida. Afeta ambos os gêneros de forma igualitária. O presente estudo trata-se de um relato de caso de um paciente que se apresentou com oftalmoplegia dolorosa de início súbito à direita com 4 dias de evolução seguido de amaurose ipslateral após um dia do início da dor.

Abstract Tolosa-Hunt syndrome (STH) is a rare disease characterized by sudden onset unilateral painful ophthalmoplegia caused by non-specific granulomatous inflammation in the cavernous sinus or superior orbital fissure (or both). Ophthalmoparesis occurs when the cranial nerves III, IV and VI are affected by inflammation. Pupillary dysfunctions may be present and is related to involvement of the sympathetic fibers that pass through the cavernous sinus in the portion of the internal carotid artery or parasympathetic fibers around the oculomotor nerve. The involvement of the first branch of the trigeminal can cause paresthesia corresponding to the distribution from the first branch (forehead). Rarely, there may be extension of inflammation beyond the cavernous sinus or superior orbital fissure and may also affect the optic nerve. There is a good response with the use of corticosteroids and there may be spontaneous remissions. Relapses occur in 40% of cases. The disease is most common after the second decade of life. It affects both genders equally. The present study is a case report of a patient who presented with painful ophthalmoplegia of sudden onset on the right with 4 days of evolution followed by ipsilateral amaurosis after one day of onset of pain.

Síndrome da fissura orbital superior associada a traumatismos craniomaxilofaciais / Superior orbital fissure syndrome associated with craniomaxillofacial traumatism

Introdução: A Síndrome da Fissura Orbital Superior (SFOS) é uma condição de ocorrência rara, inicialmente descrita por Hirchfield em 1858. Caracterizada pela presença de oftalmoplegia, ptose da pálpebra superior e midríase, podendo ocorrer parestesia da pálpebra superior e da região frontal, associada à lesão dos pares de nervos cranianos: oculomotor, troclear, abducente (III, IV e VI) e, por vezes, o nervo trigêmeo (V). A identificação da SFOS é importante, visto que sua incidência é rara no trauma, e sua identificação pode ajudar a direcionar o tratamento de forma mais adequada. Relato de caso: O presente trabalho descreve dois casos da SFOS associados a traumas craniofaciais, cita as possíveis etiologias relacionadas a essa síndrome e descreve a situação de trauma agudo. Considerações Finais: A avaliação das condições sistêmicas do paciente e de exames complementares, como tomografias computadorizadas, auxilia o diagnóstico diferencial entre patologias que acometem a região orbital e a base de crânio, fraturas e traumas craniofaciais. A identificação da SFOS no trauma agudo orienta a abordagem imediata ou precoce quando indicada, como nos casos de hematomas retrobulbares ou em grandes deslocamentos ósseos maxilofaciais com necessidade de redução cirúrgica. Nos casos com indicação de abordagem tardia, as fraturas craniofaciais são tratadas de forma conservadora, e o paciente é encaminhado para atendimento especializado... (AU)

Introduction: The superior orbital fissure syndrome (SOFS) is a rare condition and initially described by Hirchfield in 1858. Characterized by the presence of ophthalmoplegia, upper eyelid ptosis and mydriasis, and there may be paresthesia of the upper eyelid and forehead associated by the injury of the cranial nerves like: oculomotor, trochlear, abducens (III, IV and VI) and sometimes the trigeminal nerve (V). The identification of SOFS is important, since its incidence is rare in trauma, and its identification may help to target the treatment more adequately. Case report: The present study describes two cases of SFOS associated with craniofacial trauma, cites the possible etiologies related to this syndrome and describes the situation of acute trauma. Final considerations: The evaluation of the patient's systemic conditions and complementary exams, such as computed tomography, help the differential diagnosis between pathologies that affect the orbital region and the skull base, and fractures and traumatic head injuries. The identification of SFOS in acute trauma guides the immediate or early approach when indicated, as in cases of retrobulbar hematomas or large maxillofacial bone dislocations requiring surgical reduction. In cases with indication for late approach, craniofacial fractures are treated conservatively and the patient is referred for specialized care... (AU)

Recurrent Painful Ophthalmoplegic Neuropathy: a Case Report

Upon review, it is noted that recurrent painful ophthalmoplegic neuropathy (RPON) is a rare neurological syndrome characterized by recurrent unilateral headaches and painful ophthalmoplegia of the ipsilateral oculomotor nerve. As seen on brain MRI, thickening and enhancement of the oculomotor cranial nerve can be observed in these cases. We experienced a case of RPON in an adult patient who showed thickening and enhancement of the oculomotor nerve on gadolinium-enhanced 3D-FLAIR image. The authors report a case of RPON with a review of the literature.

Pattern of Extraocular Muscle Involvements in Miller Fisher Syndrome

BACKGROUND AND PURPOSE: The most-common initial manifestation of Miller Fisher syndrome (MFS) is diplopia due to acute ophthalmoplegia. However, few studies have focused on ocular motility findings in MFS. This study aimed to determine the pattern of extraocular muscle (EOM) paresis in MFS patients. METHODS: We consecutively recruited MFS patients who presented with ophthalmoplegia between 2010 and 2015. The involved EOMs and the strabismus pattern in the primary position were analyzed. Antecedent infections, other involved cranial nerves, and laboratory findings were also reviewed. We compared the characteristics of the patients according to the severity of ophthalmoplegia between complete ophthalmoplegia (CO) and incomplete ophthalmoplegia (IO). RESULTS: Twenty-five patients (15 males and 10 females) with bilateral ophthalmoplegia were included in the study. The most-involved and last-to-recover EOM was the lateral rectus muscle. CO and IO were observed in 11 and 14 patients, respectively. The patients were aged 59.0±18.4 years (mean±SD) in the CO group and 24.9±7.4 years in the IO group (p<0.01), and comprised 63.6% and 21.4% females, respectively (p=0.049). Elevated cerebrospinal fluid protein was identified in 60.0% of patients with CO and 7.7% of patients with IO (p=0.019) for a mean follow-up time from the initial symptom onset of 3.7 days. CONCLUSIONS: The lateral rectus muscle is the most-involved and last-to-recover EOM in ophthalmoplegia. The CO patients were much older and were more likely to be female and have an elevation of cerebrospinal fluid protein than the IO patients.

Primary orbital tuberculosis on the lower eyelid with cold abscess

Orbital tuberculosis is a rare form of extrapulmonary tuberculosis, even in endemic areas. It may involve the soft tissue, lacrimal gland, periosteum, or bones of the orbital wall. We present a case of orbital tuberculosis on the lower eyelid. An 18-year-old woman with no underlying disease visited our clinic for evaluation of an oval nodule (1.5× 1.2 cm) on the right lower eyelid. Incision and drainage without biopsy was performed 2 months ago in ophthalmology department, but the periorbital mass had deteriorated, as the patient had erythematous swelling, tenderness, and cervical lymphadenopathy. Visual acuity was normal; there were no signs of proptosis, diplopia, or ophthalmoplegia. Computed tomography revealed a small abscess cavity without bony involvement. We performed an excision and biopsy through a percutaneous incision under local anesthesia. Histological examination revealed a granuloma and was diagnosed as orbital tuberculosis. The patient was additionally treated with anti-tuberculosis therapy for 6 months and recovered without complication or recurrence by 7 months. Orbital tuberculosis occurs in patients with or without associated pulmonary tuberculosis, and should be considered as a differential diagnosis in patients with inflammatory orbital disease and an orbital mass. If recurrence occurs despite adequate initial treatment, we recommend an additional examination and excisional biopsy.

Visual Loss with Ophthalmoplegia after Prone Position Spinal Surgery

PURPOSE: We report a case of acute visual loss with ophthalmoplegia after prone position spinal surgery who had blood supply dependence on collateral circulation due to occlusion of the Internal carotid artery. CASE SUMMARY: A 74-year-old man was referred to the department of ophthalmology for acute visual loss and ophthalmoplegia after lumbar spine surgery performed in prone position. On the initial visit, his right visual acuity was 0.8 and the left visual acuity was negative light perception. Intraocular pressure was normal. There was a relative afferent pupillary defect and ophthalmoplegia of all directions in the left eye. Because of the ptosis of the upper eyelid in the left eye, it was impossible to tune the eye voluntarily. The cherry red spot and pale retina were observed on the fundus examination. On brain magnetic resonance imaging angiography, we found complete obstruction of the left internal carotid artery. He had intravenous injection of 1 g methylprednisolone for 3 days, and discharged with per oral medicine. After 1 month of treatment, the ophthalmoplegia was slightly improved, but visual acuity was not recovered. CONCLUSIONS: In this case, unlike previous reports, acute visual loss and ophthalmoplegia occurred after spinal surgery the patient who had collateral circulation for ocular blood supply because of complete obstruction of the left internal carotid artery. This report highlights the importance of being aware of the anatomical variant in possible complications of external ocular compression after non-ocular surgery.

Tolosa-Hunt Syndrome / Síndrome de Tolosa-Hunt

Abstract We present a case study of Tolosa-Hunt syndrome, a rare idiopathic disease, that is characterized by painful ophthalmoplegia of strong intensity, generally affecting the third cranial nerve, and, less frequently, the fourth or the sixth cranial nerves. Usually, there is no visual impairment. The treatment is based on corticosteroids with satisfactory results in most cases although recurrences can occur at intervals from months to years. In our case, the patient presented sudden pain periorbital associated with cranial nerves involvement, which have an excellent outcome after treatment with corticosteroids, with no relapses until today.

Resumo Nós apresentamos um caso de Síndrome de Tolosa-Hunt, uma doença idiopática rara, caracterizada por oftalmoplegia dolorosa, de forte intensidade, geralmente afetando o terceiro par craniano, e, menos frequentemente, o quarto e/ou o sexto par. Geralmente, não há acometimento visual. O tratamento é feito com base em corticóides com resultados satisfatórios na maior parte dos casos, embora recorrências possam ocorrer após meses a anos. Relatamos caso de paciente masculino de 36 anos, com diagnóstico prévio de sífilis congênita e esquizofrenia, com dor periocular súbita associada com envolvimento de pares cranianos, que teve melhora total após vigência de corticoterapia, sem recorrências até a presente data.
