An epigastrius (parasitic twinning in the epigastrium) was delivered via the vaginal route spontaneously and died 37 days later. The autosite had cardiac hypertrophy with VSD, PDA, and PFO and an omphalocele. The liver was partly conjoined. There was a small swelling at the lower part of the autosite's bifurcated sternum to which the parasitic left pelvis and lower extremity were attached. On the second day after birth, parasitectomy was performed. The amputated specimens consisted of a small left pelvic girdle with a free extremity, a scrotal mass, nipplelike structures and two small protuberances externally. The liver, intestines, two testes, one kidney, one ureter, and the bladder were contained within the omphalocele. Although all of the organs and external structures of the parasite had abnormal histopathological findings, differentiated muscle fibers and submucous and/or myenteric plexus were observed.
一名上腹部寄生胎（上腹部寄生性联体双胎）经阴道自然分娩，37天后死亡。自体部位有心脏肥大，伴有室间隔缺损、动脉导管未闭和卵圆孔未闭，还有脐膨出。肝脏部分相连。在自体部位分叉胸骨下部有一个小肿块，寄生的左骨盆和下肢附着于此。出生后第二天进行了寄生胎切除术。切除标本包括一个带有游离肢体的小左骨盆带、阴囊肿块、乳头样结构和两个外部小突起。肝脏、肠道、两个睾丸、一个肾脏、一个输尿管和膀胱都包含在脐膨出内。尽管寄生虫的所有器官和外部结构都有异常的组织病理学发现，但观察到了分化的肌纤维以及黏膜下和/或肌间神经丛。
