Eight of 15 patients with mediastinal cystic hygroma were found to have abnormal enlargement of neck or thoracic veins. Five of these children had aneurysmal dilatation of the superior vena cava (SVC). Three more had mild enlargement of the SVC, which was revealed only after comparison with 20 children with no evidence of mediastinal disease. Although the association of venous aneurysms and cystic hygromas has not been previously observed, their coexistence does not appear to be coincidental: None of the patients had other causes of dilatation of the SVC. Knowledge of aneurysmal veins may be helpful to the surgeon planning resection of a cystic hygroma.
15例纵隔囊状水瘤患者中有8例被发现颈部或胸段静脉异常增粗。其中5例患儿出现上腔静脉（SVC）瘤样扩张。另有3例SVC轻度增粗，这仅在与20例无纵隔疾病证据的儿童进行对比后才被发现。虽然此前未观察到静脉瘤与囊状水瘤之间的关联，但它们的共存似乎并非偶然：所有患者均无其他导致SVC扩张的原因。了解静脉瘤可能有助于计划切除囊状水瘤的外科医生。
