We report on a newborn in whom an echogenic protrusion arising in the caudal region was detected at 12 weeks' gestation. Subsequent ultrasound examinations at weeks 15 and 22 failed to demonstrate this finding. After birth, the infant was found to have a pilonidal sinus. The pilonidal sinus may represent a remnant of the embryonic appendage ('human tail') that usually disappears by the end of the 8th week of gestation. This case might support the theory of congenital pilonidal sinus origin.
我们报告了一名新生儿，在妊娠12周时检测到其尾区出现一个回声性突出物。随后在15周和22周进行的超声检查未发现此情况。出生后，发现该婴儿患有藏毛窦。藏毛窦可能代表胚胎附属物（“人类尾巴”）的残余物，通常在妊娠第8周结束时消失。该病例可能支持先天性藏毛窦起源的理论。
