Fetus in fetu (FIF) is a very rare condition in which malformed fetus is found within the body of a living twin, most commonly within the retroperitoneum. It is a parasitic fetal twin of a diamniotic, monozygotic type. It should be differentiated from teratoma by the presence of organized vertebral column and appropriately arranged other organs or limbs around it. There is no such axial arrangement in teratoma, which has also got definite malignant potential. We report a case of FIF in a 21-year-old lady who presented late with nonspecific abdominal symptoms. Preoperative diagnosis of FIF in this case was made on computed tomography, and the patient underwent exploratory laparotomy with complete excision of mass. The excised mass in a sac was proven to be FIF on the basis of gross and histopathological examination. Surgical excision is the ideal treatment even teratoma being the differential diagnosis.
胎中胎是一种极为罕见的情况，即在存活的双胎之一体内发现畸形胎儿，最常见于腹膜后。它是双羊膜、单卵双胎类型的寄生性胎儿。应通过是否存在有组织的脊柱以及其周围是否有适当排列的其他器官或肢体，将其与畸胎瘤区分开来。畸胎瘤不存在这种轴向排列，且具有一定的恶性潜能。我们报告一例21岁女性胎中胎病例，该患者因非特异性腹部症状就诊较晚。本例通过计算机断层扫描术前诊断为胎中胎，患者接受了探查性剖腹手术并完整切除肿块。经大体和组织病理学检查，切除的囊内肿块被证实为胎中胎。即使畸胎瘤是鉴别诊断之一，手术切除仍是理想的治疗方法。
