Indocianina verde em tumores da coroide

Indocyanine green in choroidal tumors

RESUMO

Os autores relatam os achados da vídeo-angiografia digital pela indocianina verde no diagnóstico diferencial de tumores da coróide. Foram estudados 13 casos: 3 hemangiomas, 4 osteomas, 3 carcinomas metastáticos e 3 melanomas malignos. Foram reconhecidas características angiográficas próprias e constantes capazes de identificar hemangiomas, osteomas e carcinomas metastáticos diferenciando-os entre si e eles dos tumores pigmentados, principalmente o melanoma maligno. No entanto, tais características angiográficas pela indocianina verde isoladas, não mostram significado diagnóstico inequívoco em tumores pigmentados da coróide. Baseados nestas observações, concluiu-se que o uso da indocianina verde em tumores da coróide, reserva a esta nova técnica de exame, importância diagnostica complementar, com limitações, no contexto do diagnóstico diferencial dos tumores da coróide.

SUMMARY

The authors report the findings of digital indocyanine green videoangiography in the differential diagnosis of choroidal tumors. There were 13 cases: 3 hemangiomas, 4 osteomas, 3 metastatic carcinomas and 3 malignant melanomas. Proper and steady angiographic characteristics were recognised, allowing to identify and differentiate hemangioma, osteoma and metastatic carcinoma among them and from pigmented tumors, including malignant melanoma. However, such indocyanine green angiography findings alone, show no unequivocal diagnostic significance in pigmented choroidal tumors. Based on these observations, the authors conclude that the indocyanine green choroidal angiography in choroidal tumors, gives to this new examination technique, a limited diagnostic usefulness in the context of the differential diagnosis of choroidal tumors.
