A Case Report of Prenatally Diagnosed Sacrococcygeal Teratoma

Abstract

Background & aim: Sacrococcygeal teratoma (SCT) is one of the most common neoplasms diagnosed during pregnancy. Sacrococcygeal teratoma is classified into four types according to the location of the lesion. Type 4 tumors are usually diagnosed in the postpartum period and have a higher potential for malignancy. The aim of the present study was to report a case of prenatal diagnosis of sacrococcygeal teratoma. Case report: The patient was a forty-year-old woman with her second pregnancy, who had a cystic lesion in the fetal abdomen without any symptoms in the routine screening ultrasound of the second trimester, and was referred to our center due to this lesion at the gestational age of 21 weeks and 5 days. In the ultrasound performed in this center, a lesion with dimensions (39.5 x 14.3 x 8.62 mm) was detected in the fetal pelvis in front of the sacrum, tumor growth and fetal heart failure were followed up with serial ultrasound. A caesarean section was performed at the 39th week of pregnancy due to the previous caesarean section of the mother, and the baby's surgery was successfully performed 72 hours after birth. The answer to the pathology of adult cystic teratoma was reported and follow-ups of the control indicated the normal and healthy growth of the child. The early diagnosis and monitoring and treatment of the disease were done by using Prenatal ultrasound evaluation. Conclusion: Prenatal ultrasound evaluation was important in both diagnosis and monitoring of tumor growth in order to detect perinatal complications such as heart failure and fetal hydrops. These prenatal assessments can lead to accurate diagnosis and appropriate treatment.
