While anterior meningoceles and teratomas are the most commonly reported lesions, an expanding body of literature suggests a broader spectrum of presacral pathology. We present three cases from our institution that expand the phenotypic range of presacral masses associated with Currarino syndrome, including lesions not previously well described in this population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>Three cases are presented.

Surgical management must be individualized and often requires a multidisciplinary approach.
