title: Presacral neurilemmoma mimicking degenerated subserosal uterine leiomyoma.
abstract: A case of presacral neurilemmoma extending into the pelvic cavity is reported. T2-weighted MR sagittal images showed a tumor resembling subserosal uterine leiomyoma with degeneration. CT revealed features distinguishing retroperitoneal neurilemmoma from gynecological tumors. The possibility of retroperitoneal neurilemmoma should be raised when a large pelvic tumor attached to the sacrum is noted on CT or MR study.
