Resumo

Doente de 59 anos, assintomática, com achado de uma tumoração ovariana na sua avaliação ginecológica de rotina e que durante os exames pré-operatórios encontrou acidentalmente um tumor mediastínico isolado, sendo então encaminhada para avaliação diagnóstica da lesão, que posteriormente mostrou ser um linfangioma cístico isolado do mediastino. O higroma cístico do mediastino é uma neoplasia benigna e extremamente infrequente, representando apenas 0,7 a 4,5% do total dos tumores mediastínicos e, dentre estes, apenas 1% é de localização exclusivamente mediastínica, sendo o diagnóstico definitivo possível apenas pelo exame anatomopatológico, e o tratamento recomendado consiste na ressecção cirúrgica completa. Os casos descritos são de relatos isolados ou séries com poucos doentes, e a sua predisposição ou sincronicidade a outros tumores é desconhecida, e, até onde conhecemos, não antes relatada.

Abstract

A 59 years old female patient, asymptomatic, with the incidental finding of an ovarian tumor in her routine gynecological evaluation, and during the preoperative examinations it was incidentally found an isolated mediastinal tumor, and then routed to diagnostic evaluation of the lesion, which later proved to be a cystic lymphangioma. The cystic hygroma of the mediastinum is a benign tumor and very infrequent, representing only 0.7 to 4.5% of all mediastinal tumors, and of these, only 1% is exclusively mediastinal in location. The definitive diagnosis is only possible by pathological examination, and the recommended treatment consists of complete surgical resection. Cases are described in isolated reports or series with few patients, and their readiness or synchronicity with other tumors, unknown, and to the best of out knowledge, not reported yet.
