Ultrasound diagnosis of immature cervical teratoma: a case report.

We report a case of cervical teratoma in a term female infant born to a 20-year-old white woman. There are rare tumors in neonates, occurring in approximately 1 in 20,000 to 1 in 40,000 live births. These tumors are accurately defined by ultrasound. Although benign, cervical teratomas cause respiratory compromise. In this case the tumor was removed surgically with no recurrence at the 10-month follow-up.
