Fetus in fetu (FIF) is a rare abnormality where a vertebrate parasitic fetus develops inside the body of another normally developing fetus. It is distinct from teratomas, tumors composed of cells from multiple germ layers and have malignant potential. Symptoms of FIF arise from the mass effect, causing abdominal distension, feeding difficulties, and pressure effects on organs. FIF is commonly found in the retroperitoneal region but can also occur in other locations. It often includes certain organs such as the vertebral column, limbs, central nervous system, gastrointestinal tract, vessels, and genitourinary tract. Early diagnosis of FIF by ultrasound, computed tomography, and magnetic resonance imaging can improve patient outcomes. Surgical resection is the primary treatment approach, aiming to alleviate symptoms, and molecular analysis helps differentiate FIF from malignant teratomas. Regular follow-up is necessary due to the potential recurrence of teratomas.
胎中胎是一种罕见的异常情况，即脊椎动物寄生胎儿在另一个正常发育胎儿的体内发育。它与畸胎瘤不同，畸胎瘤是由来自多个胚层的细胞组成的肿瘤，具有恶性潜能。胎中胎的症状源于占位效应，可导致腹部膨隆、喂养困难以及对器官的压迫效应。胎中胎常见于腹膜后区域，但也可发生于其他部位。它通常包含某些器官，如脊柱、四肢、中枢神经系统、胃肠道、血管和泌尿生殖道。通过超声、计算机断层扫描和磁共振成像对胎中胎进行早期诊断可改善患者预后。手术切除是主要的治疗方法，旨在缓解症状，分子分析有助于将胎中胎与恶性畸胎瘤区分开来。由于畸胎瘤有复发的可能，因此需要定期随访。
