“…기형종(teratoma)은 소아에서 발견되는 가장 흔한 생 식세포 종양으로, 천미부 기형종(sacrococcygeal teratoma)의 경 우 신생아에서 가장 흔한 고형 종양 중 하나로 알려져 있다. 출생아 35,000-40,000명당 1명의 비율로 발생하며, 남아에 비해 여아에서 2-4배 정도 더 흔하다 [3][4][5] . 기형종의 내부에서 다양한 종류의 양성 및 악성 병변이 동반되어 발생할 수 있는데 악성도는 진단 연령에 비례 하며 대부분 영유아기에 진단되어 완전 절제 후 좋은 예후를 보인다…”

Sacrococcygeal teratoma is the most common congenital tumor in neonates, and is reported in approximately 1/35,000 to 1/40,000 live births. Oligodendroglioma is a rare central nervous system tumor that is usually found in the cerebral hemisphere of young and middle aged adults. When associated with a teratoma, it is mainly identified in ovarian teratoma in adolescents and adults. We describe a rare case of a preterm infant with oligodendroglioma in a mature sacrococcygeal teratoma. The male neonate was born at a gestational age of 30 weeks with a protruding mass in the sacrococcygeal region. Pelvic magnetic resonance imaging showed a sacrococcygeal teratoma of approximately 11 cm comprising fat components and skeletal structure, that extended from the anterior part of the sacrum to the abdominal cavity. Radical resection was performed at 36 days of age. Macroscopically, the resected intra-abdominal mass had the characteristics of a cystic lesion, and the intrapelvic mass was a predominantly solid mixed cystic-solid lesion. Histologically, this solid lesion in the intrapelvic mass was composed of mature glial tissue, which comprised as a proliferation of monotonous cells with small and round nuclei, surrounded by a perinuclear halo (“fried egg” appearance). Additionally, these cells were immunohistochemically positive for glial fibrillary acidic protein. These findings confirmed the diagnosis of oligodendroglioma in sacrococcygeal mature teratoma. After the treatment, no recurrence was observed during the follow-up period, and no additional intervention was required. However, the patient is undergoing treatment for voiding dysfunction caused by a neurogenic bladder.

Background & Objective: Sacrococcygeal teratomas (SCTs) are uncommon germ cell tumors with significant perinatal and postnatal mortality and morbidity rate. Case Report: We present a case of large fast growing (86x63mm) mostly cystic SCT in a 27-year-old woman with 23 weeks of gestational age and normal first trimester ultrasound exam. The fetus was evaluated by both magnetic resonance imaging (MRI) and ultrasonography. Conclusion: Findings regarding tumor location, size, and content were similar for both sonography and MRI methods, though vascular pattern was detected with higher accuracy and more details by sonography. Meanwhile, MRI provided more appropriate information about tumor effects on surrounding tissue and conus location.
