(Figure 3).
The tumor was found to be compressing the upper portion of the right
atrium. The tumor was removed without the use of cardiopulmonary bypass.
The teratoma seemed to have originated in the aorta because a 2 cm area
of aortic adventitia needed to be shaved off (Figure 4).
Pathology report confirmed the mass to be a mature teratoma with tissue
types from intestinal and respiratory epithelium, smooth muscle,
skeletal muscle, cartilage, and glial tissue. There were no malignant or
immature elements seen. The tissue from the aorta showed similar mature
teratoma and the pericardium showed focal adhesions with no tumor
infiltration (Figure 5 & 6).
The infant initially had problems feeding at her one and two month
follow up visits, but was doing well at her 4 month post-operative
follow up.
