摘要：Rhabdomyosarcoma is the most common soft tissue sarcoma that primarily occurs in children and young adults. However, prenatal detection of this tumor is extremely rare. We present a case of intrauterine diagnosis of thoracic embryonal rhabdomyosarcoma at 36 weeks\' gestation.A 30-year-old woman, gravida 1, para 0, was referred at 36 weeks\' gestation because of abdominal distension and dyspnea for 2 weeks. A detailed sonographic scan revealed a slightly hyperechoic solid round mass of 74 x 71 mm originating from the anterior wall of the right-sided thoracic cage, surrounded by hypoechoic lesions inferolaterally (Figure 1A). The protruding tumor covered most of the right thoracic cavity, partly protruded outside the anterior wall of the thoracic cage with adjacent rib invasion, and compressed the left lung and heart, which were slightly shifted to the left (Figure IB). No calcification was observed. Color Doppler sonography revealed skirting vessels in the tumor. The amniotic fluid index was raised, at 39 cm. No other major malformations were detected. The biometric examination additionally showed a fetus that was consistent with gestational age. There was no relevant medical or family history, and the parents were not consanguineous. A detailed fetal scan at 32 weeks\' gestation had not shown abnormalities in any respect. A mass that became visible and grew rapidly in 4 weeks raised the suspicion of fetal malignancy. The clinical diagnosis included rhabdomyosarcoma, teratoma, Ewing sarcoma, hemangioma, and myoblastoma.
