Fig 2. Type 2 SCT in a 28-week fetus.

A, Coronal sonography view shows cystic mass (arrows) arising from the tip of the sacrum (dashed arrow).

B, Axial view shows internal septation (arrow).

C, T2-weighted fetal MR image, coronal view, shows a cystic mass (arrows) and a significant intracorporeal solid component (dashed arrows).

D, T2-weighted fetal MR image, sagittal view, confirms intracorporeal extension (dashed arrows). The internal septation (black arrow) seen by sonography is part of the mass, not an extension of the spinal canal (white arrow points to tip of high-signal-intensity CSF in spinal canal).
