RESUMO
Idiopathic orbital inflammation (IOI) is a diagnosis of exclusion, but the exclusion of other inflammatory diseases of the orbit is broad and relies on clinician experience, response to corticosteroid, or biopsy. This study aimed to investigate the presence of granulomatosis with polyangiitis (GPA) in patients initially diagnosed as IOI and describe its clinicopathological features, ANCA status, treatment, and outcome. We performed a retrospective case series study of children diagnosed with limited GPA (L-GPA) in patients with IOI. A systematic review of the literature was performed in children with GPA and orbital mass. Eleven of 13 (85%) patients with IOI had L-GPA. Two additional patients with orbital mass and L-GPA were included in this analysis. The median age was 10 years, and 75% were female. Twelve cases were ANCA positive and 77% were MPO-pANCA positive. Most patients had a poor response to treatment and had a high relapse rate. Based on literature review, 28 cases were found. Most (78.6%) were female with a median age of 9 years. Three patients were misdiagnosed as IOI. Patients with L-GPA more frequently had MPO-pANCA positivity (35%) than children with systemic GPA (18%) and were less often PR3-cANCA positive than patients with systemic GPA (18% vs. 46%). L-GPA accounts for a high prevalence of children diagnosed as IOI. The high prevalence of MPO-pANCA observed in our study may be related to L-GPA rather than with the orbital mass. Long-term follow-up, orbital biopsy, and serial ANCA testing are necessary to exclude GPA in patients with IOI.
RESUMO
Introduction There are some inflammatory, infectious, and neoplastic diseases affecting the extrinsic orbital musculature (EOM) that present with pain, decreased visual acuity, and proptosis. Imaging is fundamental to the differential diagnoses of these diseases with similar clinical presentations. The present case series report has as main objective to illustrate and discuss the main pathologies that affect the orbit. Material and Methods The present series of cases discusses the main pathologies that can affect the extraocular musculature that can be characterized by computed tomography (CT) or magnetic resonance imaging (MRI) using cases from our institution. Results and Discussion The present study compiled several cases of ophthalmopathy from our institution to illustrate and address some of these pathologies, such as orbital lymphoma, Grave disease, metastases, periorbital cellulitis, and idiopathic orbital inflammatory syndrome. The diseases are discussed according to the presentation of clinical cases with emphasis on the main imaging findings of each pathology. Conclusion Computed tomography and MRI can help in the diagnosis and follow-up of the diseases that affect the EOM. We must be conversant with the main characteristics of the pathologies presented in the present case series report, since such findings together with clinical data can confirm the diagnosis of these diseases or at least help to narrow the differential diagnoses.

RESUMEN El pseudotumor orbitario es la tercera causa de oftalmoplejía dolorosa; constituye un desafío diagnóstico pues obliga a descartar enfermedades de etiología muy diversa que lo provocan. Se presenta el caso de una paciente femenina, de color de piel blanca, de procedencia urbana, ama de casa, fumadora, que no practica ejercicios ni lleva dieta, con antecedentes de hipertensión arterial y artritis reumatoidea, que acudió al Servicio de Oftalmología por presentar síntomas inflamatorios anexiales: edema palpebral, quemosis conjuntival, vasos conjuntivales dilatados, que se acompañaban de proptosis, oftalmoplejía dolorosa con diplopía y de una masa tumoral palpable a nivel de la porción supero-externa de la órbita. Se ingresó y se le realizaron estudios imagenológicos e histológicos, que solo aportaron signos inflamatorios y una pansinusitis. Se concluyó como un pseudotumor orbitario en su forma aguda de aparición, asociada a la artritis reumatoidea, cuyo diagnóstico se realizó por exclusión sobre la base de los resultados negativos de los estudios imagenológicos y de la biopsia. Llevó tratamiento con antibióticos parenterales y altas dosis de esteroides orales con regresión del cuadro y mejoría clínica. Se decidió la presentación del caso porque en la provincia no existen reportes sobre esta entidad, y por el énfasis en cómo llegar al diagnóstico y su correcto manejo, evitando con ello secuelas en el órgano visual.
ABSTRACT Orbital pseudotumor is the third cause of painful ophthalmoplegia; it constitutes a diagnostic challenge as it forces us to rule out diseases of very diverse etiology that cause it. A female patient, of white skin color, of urban origin, housewife, smoker, who does not practice exercises or is not on a diet, with a history of high blood pressure and rheumatoid arthritis, who attended the Ophthalmology service for presenting Adnexal inflammatory symptoms: eyelid edema, conjunctival chemosis, dilated conjunctival vessels, which were accompanied by proptosis, painful ophthalmoplegia with diplopia and a palpable tumor mass at the level of the superior-external portion of the orbit was presented. She was admitted and imaging and histological studies were performed, which only revealed inflammatory signs and pansinusitis. It was concluded as an orbital pseudotumor in its acute onset form, associated with rheumatoid arthritis, the diagnosis of which was made by exclusion on the basis of the negative results of imaging studies and biopsy. She was treated with parenteral antibiotics and high doses of oral steroids with regression of the symptoms and clinical improvement. The presentation of the case was decided because in the province there are no reports on this entity, and because of the emphasis on how to reach the diagnosis and its correct management, thereby avoiding effects in the visual organ.

RESUMEN El origen del pseudotumor orbitario no es del todo conocido. Se admite su naturaleza inflamatoria granulomatosa e inespecífica en diferentes localizaciones. El pseudotumor orbitario se define como una respuesta inflamatoria celular pleomórfica, que está usualmente confinado a estructuras de la órbita y tiene una evolución limitada. En este trabajo se presenta una paciente femenina de 16 años, con diagnóstico de pseudotumor orbitario corroborado por biopsia y tomografía axial computarizada, refractaria al tratamiento con esteroides sistémicos, por lo que se decide iniciar con la aplicación de hialuronidasa y triamcinolona en el espacio peribulbar. Los casos agudos casi siempre responden rápidamente al tratamiento con cortocoesteroides, como prednisona, pero debemos tener en cuenta que existen pacientes que son refractarios al tratamiento, por lo que es necesario buscar procedimientos alternativos. Una opción es el uso de hialuronidasa para destruir las uniones extracelulares, y difundir un esteroide de manera local, como la triamcinolona, más efectiva dentro del tejido inflamatorio para provocar un efecto localizado de este. A los tres meses del tratamiento hubo una regresión total del cuadro en esta paciente(AU)
ABSTRACT The exact etiology of orbital pseudotumor is unknown, but its granulomatous unspecific inflammatory nature at various locations has been recognized. Orbital pseudotumor is defined as a cellular pleomorphic inflammatory response of limited evolution often confined to orbital structures. A case is presented of a female 16-year-old patient diagnosed with orbital pseudotumor confirmed by biopsy and computerized axial tomography, refractory to treatment with systemic steroids, due to which it is decided to start treatment with hyaluronidase and triamcinolone in the peribulbar space. Acute cases often respond fast to treatment with corticosteroids such as prednisone. It should be borne in mind that there are patients who are refractory to treatment for whom alternative treatments should be sought. An option is the use of hyaluronidase to destroy extracellular junctions and locally spread a steroid such as triamcinolone, most effectively within the inflammatory tissue to ensure its localized effect. Total regression of the patient's status was observed at three months of treatment(AU)

A neurofibromatose tipo 1 é uma doença autossômica dominante rara, com manifestações clínicas diversas. Sua apresentação mais marcante é a presença de neurofibromas (tumores da bainha neural) cutâneos ou internos, que também podem ocorrer de forma esporádica, associados a outras manifestações sistêmicas, como manchas café com leite e lesões oculares. Por serem tumores da bainha de mielina, os neurofibromas podem acometer diversos nervos periféricos, incluindo nervos da face. Apresentamos o caso de um paciente de 1 ano, portador de neurofibromatose tipo 1, com neurofibroma em nervo infraorbital direito, com o acesso proposto para tratamento cirúrgico que fornecesse ampla visualização e acesso a lesão, sem comprometimento estético importante, permitindo preservação de partes moles e adequado crescimento facial.
Neurofibromatosis type 1 (NF1) is a rare autosomal dominant disease with multiple clinical manifestations. Its most significant presentation is cutaneous or subcutaneous neurofibromas (myelin sheath tumors), which may be associated with other systemic manifestations such as caféau- lait spots and eye involvement. Neurofibromas can affect several peripheral nerves, including the facial nerves. This report presents a case of a 1-year-old patient with NF1 with right infraorbital nerve neurofibroma in which the proposed access for surgical treatment allowed adequate visualization of the tumor with good aesthetic results, preservation of the soft tissues, and normal facial growth.

Introducción: La miositis orbitaria aguda es una afección inflamatoria de la musculatura extrínseca ocular muchas veces de causa desconocida. Forma parte de un grupo de afecciones inflamatorias orbitarias inespecíficas englobadas bajo el término de pseudo tumor orbitario. Afecta principalmente a las mujeres jóvenes. Objetivo: Describir el caso de una adolescente con miositis orbitaria aguda, afección inflamatoria poco frecuente en la edad pediátrica. Presentación del caso: Se trata de una adolescente de 14 años, mestiza, femenina, quien sufrió dengue por tres ocasiones poco tiempo antes de presentarse con dolor ocular del ojo izquierdo, fiebre elevada intermitente, protrusión ocular intermitente, vómitos, cefalea, decaimiento, pérdida de peso y de apetito. El ojo izquierdo presentaba edema del parpado superior y limitación a la abducción, musculatura ocular extrínseca: diplopía horizontal a mirada derecha a izquierda. El ultrasonido ocular informa presencia de imagen quística que no impresiona ser de contenido hemático. El resultado de la tomografía axial computarizada de órbita y cráneo simple fue compatible con diagnóstico de miositis orbitaria. Se indicó tratamiento inmediato con esteroides orales y se remitió al Instituto de Oftalmología Ramon Pando Ferrer para seguimiento. Conclusiones: La miositis orbitaria exige un alto índice de sospecha para un diagnóstico y tratamiento correcto. El dengue pudiera estar implicado en la etiología de la enfermedad(AU)
Introduction: Acute orbitary myositis is an inflammatory condition of the extrinsic ocular musculature, often of unknown cause. It is part of a group of non-specific orbital inflammatory conditions encompassed by the term of orbital pseudotumors. It mainly affects young women. Objective: To describe the case of a teenager with acute orbital myositis which an inflammatory condition not frequent in the pediatric ages. Case presentation: This is a 14-year-old, mixed-race, female patient, who suffered dengue three times before presenting ocular pain in the left eye, intermittent high fever, intermittent ocular protrusion, vomiting, headache, weakness, loss of weight and appetite. The left eye presents edema of the upper eyelid and limitation in abduction. The extrinsic ocular musculature presented: horizontal diplopia in right to left gaze. The ocular ultrasound informs: cystic image that does not impress to be of hematic content. A computerized axial tomography of the orbit and simple skull was performed, and the result was compatible with the diagnosis of orbital myositis. Immediate treatment with oral steroids was indicated and the patient was sent to the Ramon Pando Ferrer Ophthalmology Institute for follow-up. Conclusion: Orbital myositis requires a high index of suspicion for a correct diagnosis and treatment. Dengue seems to be involved in the etiology of the disease(AU)

Los infartos limítrofes son aquellos ubicados en regiones entre dos territorios vasculares contiguos y la enfermedad inflamatoria orbitaria idiopática es un proceso inflamatorio orbitario inespecífico. Presentamos el caso de un varón de 60 años con exoftalmos, ptosis palpebral, disminución de agudeza visual derecha y afección de los nervios oculomotores derechos. Los estudios de imágenes mostraron una masa retro ocular derecha con invasión de los senos cavernosos y esfenoidal. Durante la hospitalización, el paciente sufrió un infarto cerebral limítrofe por compresión de la arteria carótida interna derecha en su segmento intracavernoso. La exéresis y la anatomía patológica de la lesión orbitaria fueron compatibles con la enfermedad inflamatoria orbitaria idiopática. Nuestro caso muestra a la enfermedad inflamatoria orbitaria idiopática como una causa inhabitual de infarto cerebral limítrofe.
Watershed cerebral infarctions are those located in regions between two adjacent vascular territories and Idiopathic orbital inflammatory disease is a nonspecific inflammatory process of the orbit. We report the case of a 60-year-old man who presented suddenly in the right eye: exophthalmos, ptosis, reduced visual acuity and paresis of the extraocular muscles innervated by the III, IV and VI cranial nerves. Imaging studies showed a right retro-ocular mass with invasion of the ipsilateral cavernous and sphenoid sinus. During hospitalization, suddenly he presented a watershed infarction with narrowing of the right internal carotid artery in its intracavernous portion. Surgical excision of the lesion was performed and pathology showed a characteristic infiltration of idiopathic orbital inflammatory disease. Our case shows idiopathic orbital inflammatory disease as an uncommon cause of watershed cerebral infarction.
RESUMO
RESUMO O pseudotumor esclerosante de órbita é um subtipo raro de pseudotumor inflamatório idiopático de órbita. É mais comum em adultos e apresenta diagnóstico de exclusão. A primeira linha de tratamento são os esteroides. O subtipo esclerosante apresenta resposta moderada aos esteroides devido à predominância de fibrose e colágeno na histologia. Relatamos o caso de um paciente com diagnóstico histológico de pseudotumor esclerosante de órbita que teve boa resposta ao tratamento com corticoide associado à azatioprina.
ABSTRACT Sclerosing orbital pseudotumor is a rare subtype of idiopathic orbital inflammatory pseudotumor. It's more common in adults and presents diagnosis of exclusion. Steroids represent the first option of treatment. The sclerosing orbital pseudotumor subtype shows moderate response to steroids due to the predominance of fibrosis and collagen in its histology. We report on a case of a patient with histologic diagnosis of sclerosing orbital pseudotumor successfully treated with corticosteroid associated with azathioprine.
