A well-circumscribed encapsulated abnormal signal mass lesion measuring 9.6 x 3.7 x 5.1 cm (AP x CC x T) is noted in the presacral region anterior to the L5-S3 segments, closely related to the sacral plexus. It demonstrates intermediate to low signal on T1WI, heterogeneously high signal on T2 fat sat and diffusion restriction on DWI/ADC. Post-contrast images show heterogeneous enhancement of this lesion.
