| Based on this, we propose the term sacrococcygeal extension to better describe the physical finding and its etiology. |
| At the sacrococcygeal levels, the first three sacral elements contain an additional pair of ossification centres. |
| The developmental effects noted consisted primarily of decreased number of live fetuses and fetal weights, cardiovascular abnormalities, wavy ribs and decreased number of ossified sacrococcygeal vertebral bodies. |
| The main differential diagnosis with myelomeningocele will be sacrococcygeal teratoma. |
| Consider a birth defect such as a large tumour called sacrococcygeal teratoma, which grows on the back of a little baby. |
| Reported cases, however, are mainly presacral or sacrococcygeal with an extremely rare presentation of intradural extension. |
