Two cases of cystic hygroma arising as a primary lesion in the chest are presented. Because of calcifications discovered on CT and because of the anterior location of the mass in both cases, teratoma was the first diagnostic consideration. However, after surgical removal, histologic study determined that both lesions were cystic hygromas with areas of scattered calcification probably secondary to hemorrhage. These cases are presented because of the remarkable similarity of their imaging features to those of teratoma.
本文报告两例以胸部原发性病变出现的囊状水瘤。由于CT检查发现钙化，且两例肿块均位于前部，畸胎瘤是首要的诊断考虑。然而，手术切除后，组织学研究确定这两个病变均为囊状水瘤，伴有散在钙化区域，可能继发于出血。之所以报告这些病例，是因为它们的影像学特征与畸胎瘤极为相似。
