Coats disease associated with vasoproliferative tumor treated with cryotherapy and intravitreal injections of triamcinolone / Doença de Coats associada a tumor vasoproliferativo tratada com crioterapia e injeções intravítreas de triancinolona

Abstract Report of a case of Coats disease associated with retinal vasoproliferative tumor in a young female patient with two peripheral vascularized tumors and lipid exudation involving the macula and peripapillary region with serous retinal detachment areas and pre-papillary fibrous proliferation. The proposed and performed treatment was the intravitreal injection of triamcinolone acetonide to decrease the tumor exudation, followed by photocoagulation of the peripheral areas of telangiectasia without subretinal fluid and cryotherapy of the tumors. Despite that this is a rare and difficult to treat combination, in this case report, success was obtained in receding the tumor masses and reapplying the retina, leading to anatomic and visual stabilization.

Resumo Relato de um caso de Doença de Coats associada a tumor vasoproliferativo de retina em uma paciente jovem com duas tumorações vascularizadas periféricas e exsudação lipídica acometendo mácula e região peripapilar com áreas de descolamento de retina seroso e proliferação fibrosa pré-papilar. O tratamento proposto e realizado foi a injeção intra-vítrea de triancinolona para diminuir a exsudação do tumor, seguida de fotocoagulação periférica das áreas de telangiectasia sem fluido subretiniano e criocoagulação dos tumores. Apesar de se tratar de uma associação rara e de difícil tratamento, neste relato de caso, obteve-se êxito em regredir as massas tumorais e reaplicar a retina, levando à estabilização anatômica e visual.

Metástasis coroideas: clarinada hacia la nada: presentación de casos icónicos / Choroid metastasis: clarion call toward nothing: presentation of two iconic cases

La metástasis intraoculares de tumores sólidos o hematológicos, son un problema clínico para el oftalmólogo práctico y el oncólogo. La localización más frecuente es la coroides, constituyendo el tumor intraocular más frecuente. Suelen diagnósticarsé en pacientes en estadios tumorales muy avanzados, por lo que en el pasado la mayoría de las series publicadas eran descripciones de necropsias. Su diagnóstico generalmente puede hacerse mediante cuidadoso examen. Se estima que la frecuencia general en pacientes que fallecen por cáncer es de aproximadamente 12%, pero puede elevarse en 37% en aquellos con carcinoma mamario, muy superior a la de los tumores primarios, fundamentalmente los melanomas. No obstante, sin compresión ha aumentado en años recientes ofreciendose nuevas formas de tratamiento siendo todavía la radioterapia la que permite a los pacientes mantener una visión.

Intraocular metastases of solid and hematological tumors are clinical problem for the practicing ophthalmologist and oncologist. Its diagnosis can usually be made through careful examination. The most common intraocular tumor. They are often diagnosed in patients in very advanced tumor stages, which is why in the past most of the published series were descriptions of necropsies. The overall frequency of ocular metastases in patients dying of cancer is approximately 12%, but it can be as high as 37% in patients with breast cancer, highly superior to primary tumors, mainly melanomas. Hawever, our understanding of them has increased in recent years, offering new forms of treatment. Radiation therapy is still the cornerstone of treatment, allowing nost patients to maintain usefull vision. Clinical cases with photographic support of an iconic patient are presented to illustrate the problem.

Tumor vasoproliferativo associado à tuberculose ocular presumida: relato de caso / Vasoproliferative tumor associated with presumed ocular tuberculosis: case report

OBJETIVO: Descrever um caso de tumor vasoproliferativo associado à tuberculose ocular tratado com crioterapia e injeção de triancinolona intravítrea. DESENHO DO ESTUDO/PACIENTES E MÉTODOS: Relato de caso intervencional. Paciente do sexo feminino, 42 anos, referia inflamação do olho direito havia 1 ano, não diagnosticada, tratada com prednisona oral por 30 dias. Relatava baixa visão com o olho direito (OD) desde a infância. Negava antecedentes pessoais e familiares. Ao exame ocular, apresentava acuidade visual menor que 20/400 com o OD. Não apresentava alterações à biomicroscopia e a pressão intra-ocular era normal em ambos os olhos. A fundoscopia do OD mostrava lesão vascularizada, elevada, associada ao descolamento seroso e exsudatos duros, localizada na periferia inferior da retina. A lesão era cercada por extensa área de pontos de hiperplasia do epitélio pigmentar. A mácula apresentava diminuição do reflexo foveal. No exame de ultra-som ocular, a lesão apresentava altura igual a 2,25mm e consistência sugestiva de lesão vascularizada. Foram solicitados exames sorológicos, hemograma, RX tórax e PPD. Os exames foram normais, com exceção do PPD, considerado forte reator. A paciente foi encaminhada ao infectologista, que diagnosticou tuberculose após exame de pesquisa de BK no escarro. Em face do quadro clínico, foi feito o diagnóstico de tumor vasoproliferativo da retina associado à tuberculose ocular presumida. Iniciou-se o tratamento com esquema tríplice (rifampicina, isoniazida e piridoxina). Optou-se por tratar o tumor com crioterapia e injeção intravítrea de triancinolona (4 mg/ml). Após 30 dias, a paciente apresentava diminuição do descolamento seroso e áreas atróficas na lesão tumoral. O aspecto angiofluoresceinográfico mostrava algumas áreas de enchimento precoce da trama vascular com discreto extravasamento tardio do contraste, sem áreas de oclusão capilar. A maior parte da lesão apresentava hipofluorescência por bloqueio (proliferação...

PURPOSE: To describe a case of vasoproliferative tumor associated with presumed ocular tuberculosis treated with cryotherapy and intravitreal triamcinolone injection. STUDY DESIGN/PATIENT AND METHODS: Interventional case report. A 42-year-old female patient reported inflammation of the right eye 1 year ago, treated with oral prednisone for 30 days. She referred blurred vision in the right eye since childhood. Ophthalmologic examination showed 20/400 visual acuity in the right eye. Biomicroscopy and intraocular pressure were normal. Fundus examination showed vascularized elevated lesion, associated with serous retinal detachment and hard exudates at the inferior periphery. The lesion was surrounded by extensive area of hyperplastic retinal pigment epithelium. The macula showed attenuation of the foveal reflex. Ocular ultrasound showed a 2.25 mm height vascularized lesion. Serologic examination, hemogram and thorax RX were normal. PPD was considered strong reactor and tuberculosis was diagnosed after positive BK research. Considering the clinical aspects, the ocular diagnosis was vasoproliferative tumor associated with presumed ocular tuberculosis. Treatment with rifampicin, isoniazide and pyridoxine was started. We decided to treat the ocular tumor with cryotherapy and intravitreal triamcinolone injection (4 mg/ml). After 30 days, serous detachment was smaller and the tumor showed atrophic areas. Fluorescein angiography showed areas of vascular hyperfluorescence with slight extravasation and areas of blocked fluorescence due to RPE hyperplasia. Secondary vasoproliferative tumors are retinal glial proliferations and are associated with many ocular conditions that affect retina and choroid. Because of the great number of associated complications, with important visual loss, vasoproliferative tumors should be treated at the moment of diagnosis. Treatment of choice is cryotherapy. Intravitreal triamcinolone can be used as adjuvant treatment...
