kindlicher präsakraler Tumor

Presacral

plexiform neurofibroma with urinary retention. Coronal T2 Single Shot Fast Spin Echo (SSFE), abdomen and pelvis. Large, bulky mass anterior to the lower lumbar/upper sacral spine. Multiple internal hypointense tubular structures (target sign) with rim of hyperintensity (white arrows).

Presacral

plexiform neurofibroma with urinary retention. Axial T2 Fat-saturated Single Shot Fast Spin Echo (SSFE) through the pelvis demonstrates the large pelvic mass (white arrow) displacing the rectum and bladder anteriorly. A Foley catheter is in place (red arrow).

Presacral

plexiform neurofibroma with urinary retention. Sagittal T2 Fat-saturated SSFE through the pelvis. The large presacral mass (white arrow) shows involvement of the adjacent sacral nerve roots (red arrow) and associated widening of the sacral neural foramen.

Toddler with

opsoclonus and myoclonus. Axial CT with contrast of the pelvis (above) shows (from top to bottom in the midline) contrast in the base of the bladder, contrast in the rectum which is deviated to the right, and a solid soft tissue mass anterior to the sacrum. Axial (below left) and sagittal (below right) T2 MRI without contrast of the pelvis shows the presacral mass to have high signal intensity.The diagnosis was presacral neuroblastoma.

Pediatric

case of presacral ganglioneuroma: diagnostic considerations and therapeutic strategy. Preoperative post contrast CT scan images in coronal plan (a) and axial plan (b) revealing a heterogeneous mass with the presence of calcific foci (thin yellow arrows) and sacral foraminal extension (thick yellow arrow). Preoperative MRI revealed hyperintensity on T2 weighted sagittal images where the mass had well-defined limits and foraminal extension (thick yellow arrows) anterior displacement of the ureter with subsequent hydronephrosis (thin yellow arrow) (c)
