Cysts of the thoracic duct are rare. We report a case of a cervical thoracic duct cyst and review 29 thoracic duct cysts reported previously (19 mediastinal, 9 cervical, and 1 abdominal). The mean age of the patients was 47.6 years (range 17 to 86 years). Fourteen (46.7%) of the patients were asymptomatic. When symptoms were present, they ranged from retrosternal pain, dysphagia, and dyspnea to respiratory insufficiency and superior vena cava compression. Diagnosis of the cyst can be made after computed tomography or ultrasonography. The cystic fluid contains T lymphocytes and triglycerides in excess. The symptoms in a patient with a thoracic duct cyst are related to compression of adjacent structures. The most profound symptoms are likely to be produced by mediastinal cysts above the aortic arch. Treatment consists of surgical removal of the cyst and ligation of all lymphatics connected to the cyst.
胸导管囊肿很罕见。我们报告一例颈胸导管囊肿病例，并回顾此前报道的29例胸导管囊肿（19例纵隔囊肿、9例颈囊肿和1例腹囊肿）。患者的平均年龄为47.6岁（范围17至86岁）。14例（46.7%）患者无症状。出现症状时，症状范围从胸骨后疼痛、吞咽困难、呼吸困难到呼吸功能不全和上腔静脉受压。囊肿经计算机断层扫描或超声检查后可确诊。囊液中含有过量的T淋巴细胞和甘油三酯。胸导管囊肿患者的症状与相邻结构受压有关。最严重的症状可能由主动脉弓上方的纵隔囊肿引起。治疗包括手术切除囊肿并结扎所有与囊肿相连的淋巴管。
