“…Direct vascular communication between the lesion and the vena cava system have rarely been reported [1,2]. CT images of the mediastinal lymphangiohemangioma are very rarely found in the English literature [1-4]. Moreover, neither a case with multiple masses and more than one vascular communication nor a case directly connected to the heart chamber through an anomalous vessel was found in the literature.…”

Lymphangiohemangiomas of the mediastinum are exceedingly rare and few cases have been published in the English literature. This report may be the only reported case in which lymphangiohemangiomas were found bilaterally. We report a case of a 7-year-old boy with an incidental finding of an abnormal mediastinal shadow on a chest X-ray. The chest CT showed a large mass in the left superior mediastinum and another in the right posterior mediastinum. The left mass had anomalous venous channels connected to the left innominate vein, and the right mass to the left atrium. We performed an excision of the mass in the left side first and then the right side one month later. Anomalous venous channels were dissected carefully and ligated. There were no complications and no signs of recurrence 30 months after the operation.

“…Ectasia of the SVC has been reported in adults with cystic hygromas of the chest cavity, in which the SVC was embedded in the mass but obviously not obstructed. 8 It has been postulated that perhaps ectasia of the SVC is part of the underlying malformation. Herniation from the mediastinum through the intercostal spaces, similar to that in case 1, has been reported in a neonate.…”

Objective. The purpose of this series was to evaluate the prenatal sonographic findings and postnatal outcomes in 2 fetuses with mediastinal lymphangiomas. Methods. The fetal images were compared with postnatal imaging and surgical findings. Results. The 2 fetuses had anechoic mediastinal masses at 25 and 22 weeks, which proved to be lymphangiomas. One, located in the anterior mediastinum, also enveloped the superior vena cava, brachial plexus, phrenic nerve, larynx, and lower parts of the neck vessels and extended into the subcutaneous tissues of the anterior chest wall through an intercostal space. In the second patient, the lymphangioma appeared to be a unilocular cyst, which involved the deep tissues of the neck as well as the posterior and lateral mediastinum. Both required 2 interventions after birth. Conclusions. Fetal mediastinal lymphangiomas appeared anechoic and sent extensions into the neck in the first case, around the superior vena cava, through the intercostal spaces to the skin, and around the brachial plexus in the second case, and deviated the trachea in both cases. In 1 case, there was also ectasia of the superior vena cava. This ability to entwine around vital structures can make it difficult to determine the extent of involvement on antenatal sonography and to remove lymphangiomas completely, and recurrence is common. Key words: fetal cystic hygroma; lymphangioma; mediastinum; neck; skin; superior vena cava.Received August 13, 2007, etal lymphangiomas of the chest are rare occurrences. The purpose of this series was to evaluate the prenatal sonographic findings and postnatal outcomes in 2 fetuses with mediastinal lymphangiomas. Case DescriptionsCase 1 A 22-year-old patient, gravida 3, para 2, was seen for sonographic examination at 25 weeks' gestation. A cystic mass measuring 3.3 × 0.7 cm with some small septations was located between the heart apex and left chest wall (Figure 1) and extended up around the base of the superior vena cava (SVC). The SVC appeared dilated and irregular, but no obstruction could be identified (Figure 2). No flow was seen within the cystic mass, and although there were multiple septations, there were no solid components. The differential diagnosis included a
