Imaging spectrum of spinal dysraphism on magnetic resonance: A pictorial review

Figure 23 Sacrococcygeal teratoma (type III). T2 weighted sagittal (A), T2 weighted axial (B), T1 weighted axial (C) and T1 weighted fat suppressed axial post contrast (D) images show a large heterogeneous presacral lesion. It has a large internal component which is predominately fat (arrowhead) appearing hyperintense on both T1 and T2 weighted images with signal suppression on post contrast fat saturated image. It also has a small complex solid cystic external component (arrow) appearing hyperintense on T2 wighted and hypointense on T1 weighted with enhancement on post contrast images.
