Um derrame quiloso (quilotórax) é definido pela presença de quilo no espaço pleural como resultado de obstrução ou ruptura do ducto torácico ou de um de seus principais tributários. Uma concentração de triglicérides >110 mg/dL é virtualmente diagnóstica, mas a presença de quilomícrons confirma este diagnóstico. No entanto, um quilotórax definido por estes critérios representa um grupo heterogêneo de entidades clínicas. A presença de quilomícrons ou níveis de triglicérides >110 mg/dL em um derrame pleural devem ser considerados como evidência de vazamento de quilo com significado clínico indeterminado. Muitos casos de derrame quiloso podem estar associados a outras causas de acúmulo de líquido pleural. | |||
