A 66 year old woman presented in extremis with symptoms and clinical and radiological signs of simultaneous obstruction of superior vena cava and middle lobe of right lung secondary to compression by a massive benign anterior mediastinal cyst. Excision of the cyst at median sternotomy resulted in complete resolution of all symptoms. This report is unusual on account of a) the concomitant presence of superior vena cava and middle lobe syndromes caused by a benign cyst because of its sheer size producing obstruction of these structures and b) the complete resolution of all symptoms and signs after removal of the cyst. Benign anterior mediastinal cysts are unknown to cause either of the two syndromes. To our knowledge, it is the first report of a benign anterior mediastinal cyst causing either superior vena cava syndrome or middle lobe syndrome or both simultaneously. Etiologies of both superior vena cava and middle lobe syndromes are discussed in detail.
一名66岁女性因极度危急情况就诊，其症状、临床及影像学表现提示上腔静脉和右肺中叶同时受压梗阻，病因是巨大良性前纵隔囊肿。经正中胸骨切开术切除囊肿后，所有症状完全缓解。本报告不同寻常之处在于：a）由一个良性囊肿同时导致上腔静脉综合征和中叶综合征，因其体积巨大压迫这些结构；b）囊肿切除后所有症状和体征完全缓解。良性前纵隔囊肿导致这两种综合征中的任何一种均不为人所知。据我们所知，这是首例良性前纵隔囊肿同时导致上腔静脉综合征或中叶综合征或两者的报告。文中详细讨论了上腔静脉综合征和中叶综合征的病因。
