A pregnant woman in Arkansas surprised doctors twice over when she went in for a routine ultrasound this June.
Doctors successfully located Todd and Julia Grovenburg’s growing baby girl Jillian, but then discovered another smaller baby — what could be Jillian’s younger brother — growing beside her. The Grovenburgs may have conceived their son Hudson a full two-and-a-half weeks after Jillian, according to statements given to KFSM-TV in Ft. Smith-Fayetteville, Ark. Different from identical twins or fraternal twins, the Grovenburg babies would have separate due dates and are considered to be a rare medical occurrence.
"When the woman had her ultrasound initially, they saw one sack, one baby developing, and that baby had a certain gestational age; then they noticed a second heartbeat in a child that was much, much younger developmentally," Dr. Karen Boyle of the Greater Baltimore Medical Center, told ABC News’ "Good Morning America Health."
Boyle said it’s uncommon for fetuses to differ so widely in size and development early in pregnancy, even though babies may differ widely in size at birth.
"It does really sound like this is a true case of different conception times for these children," said Boyle.
Reports of superfetation, or conceiving while pregnant, are so rare that Boyle said, "There is no prevalence or incidence in the literature. I could only find about 10 reported cases."
Grovenburg’s obstetrician, Dr. Michel Muylaert, confirmed to KFSM-TV that the Grovenburgs may be dealing with the extraordinarily rare case of superfetation.
"Mrs. Julia Grovenburg is pregnant with twins and there appears to be a discordant growth pattern, possibly due to superfetation," Dr. Muylaert wrote in a letter to KFSM-TV. "This is an unusual and rare condition, but the possibility is real. It can only be confirmed after delivery by chromosomal and metabolic studies on the babies. She was evaluated at UAMS in Little Rock for this condition and they confirmed the suspicion of superfetation," he continued.
How interesting is this? What the heck is in the water down in Arkansas? I mean – we’ve got this woman who gets knocked up when she’s already knocked up and you’ve got Mrs. Duggar who is pregnant with number nineteen! Is there anything else to do down there than have lots and lots of sex? I mean; sex isn’t bad – don’t get me wrong. But maybe the ladies down there should take up say … knitting or shuffleboard?
I wonder if this article will turn out to be true. I mean – I wonder what will happen when Mama delivers. Three weeks separation isn’t bad – a baby should be fine even if it’s born three weeks early. I guess we’ll have to stay tuned! Mama is due around the middle of December 2009 / early 2010.
