Intrapericardial teratomas are unusual tumors that often cause respiratory
distress and might be lethal in the newborn. The purpose of this article is
to present the clinical and pathological findings in a 12-day-old male suc
cessfully treated for a big intrapericardial teratoma. Given that the diame
ter of this tumor is generally related to the age at the time of diagnosis,
the rarity of our case is the presence of a huge intrapericardial teratoma
in a newborn. The surgical resection was lifesaving.
