A 14-year-old
male patient was admitted for an abnormal
chest X-ray. A
chest computed tomogram showed a cystic mass in the anterior
mediastinum and
spleen, 14X14 cm and 2X2 cm in size respectively. Complete removal of the mediastinal lesion was achieved by a
median sternotomy. The final histologic
diagnosis of the lesion was
cystic lymphangioma. There was no evidence of
tumor recurrence until a
postoperative period of 14 months.
