ABSTRACT
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)

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.
