RT Journal Article SR Electronic T1 Terminal Myelocystocele and Sacrococcygeal Teratoma: A Comparison of Fetal Ultrasound Presentation and Perinatal Risk JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1058 OP 1060 DO 10.3174/ajnr.A0502 VO 28 IS 6 A1 Yu, J.A. A1 Sohaey, R. A1 Kennedy, A.M. A1 Selden, N.R. YR 2007 UL http://www.ajnr.org/content/28/6/1058.abstract AB SUMMARY: This case exemplifies the difficulty in differentiating cystic sacrococcygeal teratoma and terminal myelocystocele. Fetal sonography presentation and perinatal risks of sacrococcygeal teratoma and terminal myelocystocele are compared, and we emphasize the importance of obtaining fetal MR imaging to establish an accurate diagnosis.
