Sacrococcygeal teratoma

quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "These lesions are best resected within the first 24 h after birth, because the gut is usually not colonized in the first 24 h, reducing the risk of infection if the field is contaminated by stool during the resection. Perioperative antibiotics are given immediately before surgery commences and continued for 24–48 h postoperatively."

quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "An abdominal ultrasound will determine the size and consistency of any pelvic or abdominal component. It may be necessary to fill the bladder with water to allow it to be used as a sonic window. MRI should clearly distinguish between sacrococcygeal teratoma and anterior meningocele, and may be able to detect the occasional extension of the tumour through the sacral hiatus into the spinal canal."
