Sacrococcygeal teratoma with intradural extension: case report

Abstract

<jats:p>Intradural sacrococcygeal teratoma (SCT) is a rare entity that has been reported in only a few cases previously. The authors present the case of a 2-week-old, otherwise healthy neonate with a mass in the buttock. The imaging findings and the high level of serum alpha-fetoprotein were highly suggestive of SCT. On operation the authors found intradural extension of the teratoma. The lesion was managed successfully without any remaining sequelae. The authors briefly review the currently proposed etiology regarding teratoma formation and the intradural extension of SCT.</jats:p>

Surgical treatment of a type IV cystic sacrococcygeal teratoma with intraspinal extension utilizing a posterior-anterior-posterior approach: a case report

“…Sacrococcygeal teratomas represent the most common form of fetal teratoma [ 17 , 29 ]. The majority of cases present as a benign exophytic mass lesion, identified at birth or on prenatal ultrasound, and can be associated with a variety of other findings, including trisomy 21, club feet, congenital dysplasia/luxation of the hip, hypospadias, congenital urethrovaginal fistula, and obstructive uropathy [ 6 ].…”

“…To our knowledge, there are few documented cases of sacrococcygeal teratomas with intraspinal involvement, and true spinal cord involvement with intradural extension is even less common [ 11 , 15 , 17 , 26 , 27 , 29 ]. The majority of sacrococcygeal teratomas with intraspinal extension are Altman type I or II lesions.…”

“…Sacrococcygeal teratomas have an incidence of 1 in 35,000 to 40,000 live births and are typically diagnosed either via prenatal ultrasound, or during a postnatal physical examination [ 20 ]. Despite the close anatomic relationship of sacrococcygeal teratomas with the spine, true spinal canal involvement is rare [ 11 , 15 , 17 , 26 , 27 , 29 , 31 ]. Here, we report the first case, to our knowledge, of a type IV sacroccoygeal teratoma with intraspinal, extradural extension that underwent an en bloc gross total resection via a posterior-anterior-posterior approach.…”

Early Delivery of Sacrococcygeal Teratoma with Intraspinal Extension

“…There are reports of teratomas occurring within a meningomyelocele [6] and tethered cord occurring with SCT [7] . Intraspinal extension is a rare complicating factor that has been previously reported [8][9][10][11][12] . The associated spinal problems are typically dealt with postnatally during the tumor resection and utilize a multidisciplinary surgical approach.…”

Sacrococcygeal Teratoma - An Interesting Case and Infrequently seen Extension in Spinal Cord

“…Treatments of SCT that have spinal extension consist of complete resection of the tumor followed by close follow up. Post-operative complications include haemorrhage, bleeding, neurological deficit, bladder dysfunction and recurrence [10,11].…”
