BACKGROUND:

Prenatal misoprostol exposure can be associated with a spectrum of birth defects, ranging from central nervous system abnormalities, Moebius sequence, abdominal wall defects, as well as transverse limb defects, fetal abnormalities are more commonly seen with the use of the misoprostol-only regimen for induction of abortion, such that a thorough medical history is essential to detect a history of prenatal exposure after a failed abortion.

CLINICAL CASE:

A 21-year-old patient, with a 32-week pregnancy, who attended the institute with a diagnosis of a fetus with ventriculomegaly, the ultrasound evaluation highlighted severe symmetric triventricular ventriculomegaly and angulation of both lower extremities in varus, magnetic resonance imaging reported severe non-communicating ventriculomegaly Symmetric bilateral, due to probable stenosis of the aqueduct of Silvio, the karyotype reported 46, XY, as well as a negative TORCH profile, however, a cesarean section was performed for fetal indication at 35 weeks, the evaluation at birth showed bilateral facial paralysis, macrocephaly and foot Bilateral equinus varus, upon re-examination the patient referred the use of misoprostol in the first trimester of pregnancy for abortive purposes, so as there were no chromosomal or infectious alterations, a Moebius sequence was suggested.

CONCLUSIONS

: Prenatal exposure to misoprostol is related to the appearance of vascular disruption defects in some exposed fetuses, the precise spectrum and potential estimation of teratogenicity have not yet been determined, the clinical history is the mainstay for the association in these cases.
