RESUMEN
Neonatal tumors occur infrequently; sacrococcygeal teratoma (SCT) is a rare and abnormal mass often diagnosed on antenatal ultrasound. An SCT may cause serious antenatal complications, requires surgery in the neonatal period, and can lead to various long-term sequelae including fecal incontinence or constipation, urinary incontinence, and lower extremity mobility impairment. Even rarer are SCTs that include intraspinal extension necessitating complex neurosurgical intervention to relieve possible spinal cord compression or tumor tissue resection. A comprehensive understanding of the natural history of SCT provides frontline neonatal nurses and nurse practitioners with the expertise and language to support families during an infant's NICU admission. A glossary of key terms accompanied by a case review of a premature infant born with a large external SCT with intrapelvic and intraspinal components aids in enhancing knowledge related to the potential impact of an SCT on the central nervous system.
