SÍNDROME DE BODY STALK: RELATO DE CASO.

Background: Body Stalk Syndrome (BSS) is a rare condition with a reported frequency of one case in every 31,000 pregnancies, and is characterized by severe congenital malformations, mainly thoracoschisis, abdominoschisis, limb defects and exencephaly. Its exact etiology is unknown and no teratogenic factor has been described so far. Furthermore, reports of familial recurrence suggest the possibility of a genetic origin for the condition. Aim: To report a case of SBS seen in our Service. Case report: This was a 23-year-old patient, with no comorbidities and a primigravida, who was referred to high-risk prenatal care due to a 2.5 mm nuchal translucency, observed by a morphological ultrasound (USG) performed with a gestational age (GA) of 11 weeks and 4 days. Two subsequent USGs showed signs suggestive of increasing SBS. The patient spontaneously went into labor with a GA of 33 weeks and 6 days. The fetus didn't have any cardiac activity since it's cefalicus disattachtment. After birth, multiple malformations were found confirming SBS. The mother received puerperal care and was discharged the following day. Conclusion: SBS is a rare and lethal malformation, justifying case reports that contribute to continuing medical education in Gynecology and Obstetrics. As seen in the case reported here, USG is important in the hypothesis of early diagnosis of SBS, allowing the pregnant woman to choose whether or not to terminate her pregnancy. There is also evidence that fetal magnetic resonance imaging could provide bases for a prenatal diagnosis of the syndrome during the beginning of the second gestational semester, as well as the diagnostic capacity of USGs for fetuses with GA at 11 and 12 weeks.
