UMBILIKAL KORD KİSTİ: OLGU SUNUMU Umblical Cord Cyst: Case Report

Umbilikal kord kistinin birinci trimesterde prevalansı %0.4-%3.4 olarak bildirilmetedir. 2.ve 3. trimesterdenadir sonografik bulgu olduğundan prevelansı bilinmemektedir. Kord kistleri ve fetalanomaliler arasında ilişki bulunabilmektedir. 33 yaşında G2 P1 A0 Y1 olan , 20 hafta 3 günlük umbilicalkordun fetusa yakın kısmında 3x2 cm çapında kistik lezyon bulunan gebeyi prenatal tanıamacıyla inceledik. Başka patolojik bulgu saptanmayan gebeye istişare sonucunda amniyosentezyapıldı. Karyotipanalizi 46 XY, normal karyotip olarak geldi. İlave malformasyon bulunmadan dakromozom alanomali olabileceğinden fetal karyotip bu olgularda incelenmelidir. İlave anomalileribulunmayan ve karyotipi normal olan olgularda fetal prognozun iyi olacağı tahmin edilebilir.ABSTRACTFirst trimester umbilical cord cysts prevalence is between 0.4 % and 3.4 %. But, in second andthird trimesters, real prevalence of umbilical cord cysts is unknown as they are not common. Theremight be associations between fetal anomalies and cord cysts. We observed a thirty-threeyear-old (gravida 2, parity 1) pregnant woman who referred at 20 weeks gestation due to 3x2 cmumbilical cord cyst formation for prenatal diagnosis purposes. In second trimester sonography,there was no other pathological finding and amniocentesis was performed in consequence ofconsultation. Karyotype analysis revealed normal 46 XY. The fetal karyotype should be investigatedin these cases as there may be a chromosome anomaly without additional malformation. Goodfetal prognosis can be predicted in cases with no additional anomalies and with normal karyotype.
