Diagnostic imaging studies help confirm the diagnosis of a clinically palpable sacrococcygeal mass, determine its relationship to other structures, and detect metastases. Sacrococcygeal teratoma radiology discussion including radiology cases. Etiology: teratoma arising in sacrococcygeal region Imaging: location is extrapelvic / intrapelvic / mixed, appears cystic / solid / mixed Thursday, November 26, 2009 MRI, sacrococcygeal teratoma Sacrococcygeal teratoma is the most common tumour of the fetus and neonate, with a reported incidence of 1 in 35,000-40,000. This neoplasm is composed of tissues from all three germ layers.

Following surgery the patient was treated with radiotherapy (150 Gy). At present (4 years after surgery) the patient has no evidence of recurrence. Sacrococcygeal teratoma (SCT) is a tumor that develops before birth and grows from a baby's coccyx — more commonly known as the tailbone.

Fetal sonography presentation and perinatal risks of sacrococcygeal teratoma and terminal myelocystocele are compared, and we emphasize the importance of obtaining fetal MR imaging to establish an accurate diagnosis. The terminal spine presents unique imaging challenges, particularly in the case of large cystic masses.

Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Sacrococcygeal Teratoma Sacrococcygeal teratomas have an incidence of one in 35 000 to 40 000 live births but represent greater than 50% of all fetal tumours. 1, 2 They occur more frequently in females than males by a factor of 4 : 1, although malignancy is more likely in males, and the tumours generally develop in the posterior sacrococcygeal region as early as the second to third week of pregnancy. 3 Sacrococcygeal teratoma is the commonest extragonadal teratoma arising from the caudal end of the spine. The incidence is approximately 1 in 40 000 live births 2,3.

Tumors greater than 10cm in diameter require cesarean. • Some of the SCTs are cyst-type tumors, meaning they are filled with fluid. Created by VideoShow:http://videoshowapp.com/free Sacrococcygeal teratoma, although rare, is the most common tumor of the newborn, and has commonly been diagnosed at birth. With an increased utilization of ultrasonography, more sacrococcygeal teratomas are now discovered in utero. Prognostic differences exist when comparing fetal sacrococcygeal teratoma and neonatal sacrococcygeal teratoma. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Sacrococcygeal Teratoma Sacrococcygeal teratomas have an incidence of one in 35 000 to 40 000 live births but represent greater than 50% of all fetal tumours.

The coccyx is almost always involved 6. Sacrococcygeal teratoma (SCT) is a tumor originating from the sacral-coccygeal region of the body. It is defined as a neoplasm composed of all three primordial tissue germ layers or a neoplasm formed from multiple tissues that are foreign to that part of the body, lacking in any organ specificity. Sacrococcygeal teratoma is the most common solid tumor in neonates. Malignant sacrococcygeal germ cell tumors also occur in infants and children. Diagnostic imaging studies help confirm the diagnosis of a clinically palpable sacrococcygeal mass, determine its relationship to other structures, and detect metastases.

Sacrococcygeal teratoma (SCT) is a tumor that develops before birth and grows from a baby's coccyx — more commonly known as the tailbone. It is the most common tumor found in newborns, occurring in 1 out of every 35,000 to 40,000 live births.

All patients showed a presacral tumor with heterogeneous intensity on CT images. The sacrococcygeal teratomas appeared cystic with few septa in three fetuses, markedly septated or even microcystic in eight, and completely solid in one. The sonographic description of the content corresponded well to MR imaging findings in 10 of 12 fetuses. Sacrococcygeal teratomas are the most common solid tumor in newborn infants. The diagnosis is not difficult in many cases; however, there should be additional information on imaging studies in order to manage those infants properly.
