Abstract:
Most giant sacral schwannomas are associated with moderate to massive bone destruction before they extend into the presacral space. These lesions can, on rare occasions, manifest as a giant tumor in the presacral space without bone destruction. We report here on the image findings of a presacral giant schwannoma in a 65-year-old man. On ultrasound and CT, the tumor appeared as an inhomogenous, well-demarcated mass that demonstrated some cystic changes and peripheral calcifications without sacral bone destruction. On the MR imaging, the tumor showed as an inhomogeneous, encapsulating mass with low signal intensity on both the T1 and T2-weighted images, except for some areas that showed cystic change.
