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

Öz

Umbilikal kord kistinin birinci trimesterde prevalansı %0.4-%3.4 olarak bildirilmetedir. 2.ve 3. trimesterde

nadir sonografik bulgu olduğundan prevelansı bilinmemektedir. Kord kistleri ve fetal

anomaliler arasında ilişki bulunabilmektedir. 33 yaşında G2 P1 A0 Y1 olan , 20 hafta 3 günlük umbilical

kordun fetusa yakın kısmında 3x2 cm çapında kistik lezyon bulunan gebeyi prenatal tanı

amacıyla inceledik. Başka patolojik bulgu saptanmayan gebeye istişare sonucunda amniyosentez

yapıldı. Karyotipanalizi 46 XY, normal karyotip olarak geldi. İlave malformasyon bulunmadan da

kromozom alanomali olabileceğinden fetal karyotip bu olgularda incelenmelidir. İlave anomalileri

bulunmayan ve karyotipi normal olan olgularda fetal prognozun iyi olacağı tahmin edilebilir.

ABSTRACT

First trimester umbilical cord cysts prevalence is between 0.4 % and 3.4 %. But, in second and

third trimesters, real prevalence of umbilical cord cysts is unknown as they are not common. There

might 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 cm

umbilical cord cyst formation for prenatal diagnosis purposes. In second trimester sonography,

there was no other pathological finding and amniocentesis was performed in consequence of

consultation. Karyotype analysis revealed normal 46 XY. The fetal karyotype should be investigated

in these cases as there may be a chromosome anomaly without additional malformation. Good

fetal prognosis can be predicted in cases with no additional anomalies and with normal karyotype.
