“…An anterior myelomeningocele can masquerade as a presacral cystic lesion, although one would expect to find associated spinal and intracerebral abnormalities. Some reports of SCTs are associated with vertebral body abnormalities which further complicates the differential diagnosis [16].…”

Sacrococcygeal teratomas (SCT) are the most common congenital tumors in the newborn. The prevalence rate is approximately 1 per 40,000 births, with 80% occurring in females. The majority of these tumors are external, protruding from the perineal region. Intrapelvic SCTs, by contrast, are extremely rare and difficult to diagnose in utero. Only 15% of the SCTs are entirely cystic, the majority being mixed or solid tumors. We describe a case of a fetal cystic presacral (grade IV) SCT, discovered at 22 weeks of gestation, which resulted in bilateral ureteral obstruction and hydronephrosis. This is the first known reported case of prenatally decompressing a cystic SCT via an amniotic catheter to alleviate a mass effect in the fetus.

Objective: A subset of fetuses with sacrococcygeal teratomas (SCT) develops hydrops caused by high-output heart failure. Identification of fetuses at risk for hydrops is important because surgical intervention may reverse the pathophysiology of the disease. The aim of this study was to evaluate sonographic prognostic factors regarding tumor morphology and vascularity associated with the development of hydrops in utero. Methods: Over a 10-year period, we identified 7 fetuses with SCT diagnosed antenatally and managed at the University of Mainz. We retrospectively reviewed the charts of mothers and infants and recorded data on prenatal diagnosis, tumor size and localization, perinatal management, neonatal care, and fetal outcome. Results: The diagnosis of SCT was made in all cases by ultrasound. The median gestational age at the time of initial diagnosis was 23 weeks. In 3 cases, signs of fetal heart failure were detected by ultrasound. Pathological blood flow in the venous system was further noted in 2 cases. One fetus developed hydrops. The mean gestational age at delivery was 35 weeks, depending on the presence or absence of maternal or fetal complications. Six infants were delivered by cesarean section, and 1 by vaginal delivery. After fetal stabilization, surgery was performed in 5 of 7 cases. Inadequate ventilation secondary to prematurity was a contributing factor to death in 1 fetus. One fetal intrauterine death occurred at 27 weeks of gestation. Conclusion: Pregnancies with antenatally diagnosed fetal SCT necessitate frequent monitoring to ensure the detection of fetal/maternal complications by ultrasound and Doppler ultrasound. The most important prognostic criteria were cardiomegaly, fetal hydrops, and increased preload indexes of the fetal venous system as sign of fetal heart failure. Many studies show that the occurrence of pulsations in the umbilical vein of a hydropic fetus correlates with a poor fetal outcome. The decision on the optimal time of delivery should therefore be made by a multidisciplinary team of specialists.

“…Compression or infiltration of the sacral nerves by the tumour and surgical trauma to hypogastric nerves during tumour resection cause damage to the innervation of the lower urinary tract in sacrococcygeal teratoma 11,14,[27][28][29][30][31] . In addition, neuropathic bladder, vesicoureteric reflux, incontinence, recurrent urinary tract infections and impotence are possible complications after resection of sacrococcygeal teratomas 10,29,32,33 .…”
