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.

Abstract Book 2017 - Yumpu
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 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.

Six patients were evaluated using a combination of computed tomography (CT) and magnetic resonance imaging (MRI). 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.
The diagnosis of sacrococcygeal teratoma was accurate in all cases assessed at our center using both MRI and sonography. Two additional patients initially referred with the diagnosis of sacrococcygeal teratoma had a different diagnosis at reevaluation at our institution (healthy, n = 1; myelomeningocele, n = 1).
