Fetus in fetu is an extremely rare condition wherein a malformed fetus is found in the abdomen of its twin. This entity is differentiated from teratoma by its embryological origin, its unusual location in the retroperitoneal space, and the presence of vertebral organization with limb buds and well-developed organ systems. The literature cites less than 100 cases worldwide of twin fetus in fetu.
A two-and-a-half-month-old Asian Indian baby boy had two malformed fetuses in his abdomen. The pre-operative diagnosis was made by performing an ultrasound and a 64-slice computer tomography scan of the baby's abdomen. Two fetoid-like masses were successfully excised from the retroperitoneal area of his abdomen. A macroscopic examination, an X-ray of the specimen after operation, and the histological features observed were suggestive of twin fetus in fetu.
Fetus in fetu is an extremely rare condition. Before any operation is carried out on a patient, imaging studies should first be conducted to differentiate this condition from teratoma. Surgical excision is a curative procedure, and a macroscopic examination of the sac should be done after twin or multiple fetus in fetu are excised.
胎内胎是一种极其罕见的情况，即在其双胎之一的腹部发现一个畸形胎儿。该实体通过其胚胎学起源、在腹膜后间隙的异常位置以及存在带有肢芽和发育良好的器官系统的椎体组织，与畸胎瘤相鉴别。文献记载全球范围内胎内双胎病例不到100例。
一名两个半月大的亚洲印度男婴腹部有两个畸形胎儿。通过对婴儿腹部进行超声检查和64层计算机断层扫描做出术前诊断。从其腹部的腹膜后区域成功切除了两个类胎儿样肿块。术后对标本进行的宏观检查、X线检查以及观察到的组织学特征提示为胎内双胎。
胎内胎是一种极其罕见的情况。在对患者进行任何手术之前，应首先进行影像学检查以将这种情况与畸胎瘤相鉴别。手术切除是一种治愈性方法，在切除胎内双胎或多胎后应对囊进行宏观检查。
