Review
Sacrococcygeal teratomas (SCT) in adults are extremely rare, and most SCTs are located either mainly outside the pelvis, with a small number of intrapelvic components, or mostly in the pelvis (types III and IV). The etiology of teratomas remains unknown. Most teratomas are benign, and approximately 1 to 2% of teratomas undergo malignant transformation, including squamous cell carcinoma, adenocarcinoma, sarcoma, and other malignancies. Most SCTs grow insidiously, and their symptoms are not easily detected in the early stages. Some cases may only be discovered through physical examination or compression symptoms when the tumor reaches a detectable size. Computed tomography and magnetic resonance imaging have high detection rates for presacral space-occupying lesions and can provide imaging details with guiding significance for the selection of surgical methods. Surgical resection is the preferred treatment option for SCT and can determine the pathological type. Common sacrococcygeal malignancies are mainly immature teratomas and mature teratomas. When the presence of malignant components is confirmed, the treatment model should be adjusted according to pathological type.

Review
BACKGROUND
Sacrococcygeal teratoma is one of the most common congenital tumors in newborns and infancy. The incidence is 1 per 20,000-40,000 live births. Ultrasonography is an optimal method for prenatal screening and diagnosis of fetal sacrococcygeal teratoma. MRI can be used to assist in the diagnosis. However, sacrococcygeal teratoma in the twin pregnancy is rare.
CASE PRESENTATION
We reported a case of one twin with sacrococcygeal teratoma in dichorionic-diamniotic twin pregnancy.One twin with sacrococcygeal teratoma was diagnosed at the second trimester by ultrasonic examination and another twin was normal. A regular and careful antenatal care was conducted by the multidisciplinary team. The parents refused to perform the fetal MRI and examine the chromosome of both twin.At 37 + 1 of gestation, planned cesarean section was performed. The healthy male co-twin (twin A) weighed 2880 g.The male twin with SCT (twin B) weighed 2900 g, complying with 6 × 3 × 3 cm cystic and solid mass in sacrococcygeal region. At four days of age twin B underwent excisional surgery of the sacrococcygeal teratoma and coccyx and discharged 7 days after surgery. The mother and both babies were followed up and are all in good health until now.
CONCLUSION(S)
Sacrococcygeal teratoma in twin pregnancy is rare. Early antenatal diagnosis is important. Once the sacrococcygeal teratoma is diagnosed, clinicians should be aware of the associated maternal and fetal complications. Expecting parents should be counseled by the multidisciplinary team about the management and prognosis of the STC twin and co-twin. Prompt surgical excision of the sacrococcygeal teratoma after birth should be suggested.

Review
OBJECTIVE
To review the current and relevant literature pertaining to the origin, imaging, and treatment for the sacrococcygeal teratoma in order to obtain information beneficial for radiologic technologists.
METHODS
Both peer-reviewed articles and contemporary imaging textbooks were used in the research for this review. The material was analyzed further for practical and instructive components for imaging professionals.
RESULTS
The inquiry regarding the origin, imaging, and treatment of the sacrococcygeal teratoma yielded important facts and clinically useful information that radiologic technologists can use.
CONCLUSION
Because the sacrococcygeal teratoma is the most common congenital tumor found in newborns, all imaging professionals who may be asked to actively or indirectly care for a patient diagnosed with the condition should have a fundamental knowledge of the origin, imaging, and treatment of this potentially fatal tumor.

Review
Familial sacrococcygeal teratomas are very rare. Up to now, only 8 kindreds (31 patients, including 1 Japanese kindreds) have been reported. All cases are Altman type IV variety. The tumor complex consists of a presacral teratoma and sacrococcygeal bony anomalies. The most common symptoms are constipation and anorectal stenosis. Two patients died. One died of meningitis following removal of a large benign tumor because of communication with a spinal arachinoid space. The other, with a large benign tumor, died as a result of malignant change, 10 years later after the first operation. The incidence of malignant change of familiar sacrococcygeal teratoma is rare in comparison with that of non-familiar sacrococcygeal teratomas.

Review
Early prenatal diagnosis of fetal sacrococcygeal teratoma (SCT) has enabled the perinatal team to institute management of this condition during the perinatal period. We report 2 additional cases to our previous 27 cases including 1 which represents the earliest diagnosis of SCT. Fetal SCT behaves in a different manner than neonatal SCT. In utero manipulation of fetal SCT may be possible if diagnosis is made during the second trimester.

This retrospective study details our experience regarding 72 patients with sacrococcygeal teratoma treated over a period of 17 years. The sex incidence was nearly equal, but there was a high proportion of Altmann type IV tumors. A preliminary colostomy before combined abdominosacral excision of large type III and IV lesions reduced morbidity. Sixty-six percent of the patients presented beyond the neonatal period; 14 had been treated elsewhere for bowel/urinary obstruction. Imaging studies included radiography, abdominal ultrasound, computed tomography, and magnetic resonance imaging (after 1995). In 60 patients the tumor was excised via the sacral route, 11 had a preliminary colostomy, and 1 had a vesicostomy. Eight children (5 with malignant lesions) required abdominosacral excision. After 1990, serial estimation of serum alpha-fetoprotein (AFP) was used to monitor tumor recurrence. There were 34 male and 38 female patients (age range 3 days-12 years); 47 had benign tumors, of which 42 were excised through the sacral route. Three patients underwent a preliminary colostomy and abdominosacral excision of the tumor with subsequent colostomy closure. There were 4 deaths in this group; no recurrence was seen in the surviving children with benign tumors. Twenty-five patients had malignant teratomas. In 18 of these the tumor was excised via the sacral route and 5 underwent abdominal-sacral excision. Eight had a preliminary colostomy and chemotherapy followed by excision of the residual tumor and colostomy closure. None of the initial 14 patients with malignant lesions survived beyond 2 years. Of the latter 11 (who received cisplatinum-based chemotherapy), 10 were alive 1 year after surgery. One patient is currently on preoperative chemotherapy and another developed recurrence of the tumor. The overall follow-up ranged from 3 months to 8 years; there has been no complaint of functional neurological deficit in any of the patients. As intrapelvic tumors tend to have a delayed diagnosis, this can be avoided by performing a rectal examination. There should be no recurrence after excision of a benign teratoma. Cisplatinum-based chemotherapy has improved the survival of patients with malignant tumors.

Review
Intraocular teratomas are rare neoplasms with only three previously reported cases. We present the fourth case of intraocular teratoma and the second associated with sacrococcygeal teratoma. While the nature of the association between intraocular teratomas and sacrococcygeal teratomas is unclear, it suggests a need for careful ophthalmologic follow-up of infants with congenital sacrococcygeal teratomas.

Eight cases of sacrococcygeal teratoma are described. Seven patients were diagnosed at birth, and one presented at 3 1/2 months of age with urinary retention. Two patients had associated congenital anomalies (arachnoid cyst, external angular dermoid and bifid sacrum), while one had a family history of sacrococcygeal teratoma. All had the tumour removed together with the coccyx as soon as the diagnosis was made. None had recurrence of the tumour.
