Uveitis Masquerade Syndrome Presenting as a Diffuse Retinoblastoma Síndrome Mascarada Por Retinoblastoma Difuso
ثبت نشده
چکیده
Caso clínico: Paciente de tres años con sospecha de uveítis intermedia. La exploración oftalmológica, ecografía ocular, resonancia nuclear magnética y tomografía computerizada orbitaria no fueron concluyentes. La determinación de la tasa de lactato deshidrogenasa (LDH) en humor acuoso/suero fue la clave para llegar al diagnóstico de un retinoblastoma difuso. Discusión: El síndrome mascarada es la forma de debut en un 1-3% de los retinoblastomas. La punción de cámara anterior está contraindicada en pacientes con retinoblastoma pero podría ser la única forma de llegar a un diagnóstico correcto en estos casos difíciles y poco frecuentes. Las pruebas enzimáticas como la LDH nos ofrecen una buena sensibilidad y especificidad para el diagnóstico de estos pacientes.
