Prenatal diagnosis of sacrococcygeal teratomas by two‐ and three‐dimensional ultrasound

Abstract

We suspected two fetuses of having sacrococcygeal teratomas following initial two-dimensional ultrasound scanning at 18 and 22 weeks' gestation. The fetuses were then scanned with three-dimensional multiplanar surface and three-dimensional orthogonal planar ultrasound to establish a definitive diagnosis. Although we made a presumptive diagnosis in both cases after initial two-dimensional scanning, with three-dimensional ultrasound we were better able to define the degree of involvement of the sacrum and other pelvic structures of prognostic importance.

Outcome of antenatally diagnosed sacrococcygeal teratomas: single-center experience (1993-2004)

“…There is still a high mortality despite such attempts to reduce the vascularity of these tumors, and perhaps, this is because of their ability to develop rapidly a collateral blood supply. Most authors conclude that if fetal intervention is to be a success, then it should be implemented before the development of high-output cardiac failure, and therefore, the clear task should be to discriminate such fetuses at an earlier stage [7,[21][22][23][24][25].…”

Three-dimensional ultrasound imaging of the pressure ulcer. A case report

“…Recently, several studies have examined the role of 3D-US in the evaluation of superficial tissue [10][11][12] and in the monitoring of changes in the tumor volume [13,14]. In this study, multi-planar reconstructed 3D-US images provided accurate images of the undermining's extension into adjacent structures and of its internal properties.…”

“…Fetal teratomas are most commonly located in the sacrococcygeal region (40%). 11 Only 5% of fetal teratomas are located in the cervical region.…”
