4D Ultrasound – Obstetric Ultrasound – Sacro-coccygeal Teratoma in 4D Scan | Panorama Scan: 4D Ultrasound - Obstetric Ultrasound - Sacro-coccygeal Teratoma in 4D Scan. It is a congenital germ cell tumor arising from the presacral area. Occurs in 1/40000 births and the sex ratio is 4:1 (f:m). It arises from the primitive knot of Hensen's. Segregation of these totipotential cells from the Hensen's node to the sacral area is the underlying cause of these tumors. It is divided into four morphologic types and three histopathologic types (mature, immature and malignant). The 3D or 4D ultrasound diagnoses depends on the demonstration of a mass arising from the sacral area and protruding through the perineum. The mass is either, cystic, solid or mixed and covered with skin and the underlying spine is intact. hypervascularity and abnormal flow pattern may confirm the possibility of malignancy.
