Pelvic tumor

A pelvic tumor is any one of numerous tumors that occur in the pelvis. Within the pelvis, these tumors may involve specific organs, or occupy intra-organ spaces. Tumors of the presacral space and sacral space are most prevalent in children. Tumors occupying specific organs have a more complex natural history.
