Sacrococcygeal Teratoma with Split Spinal Cord Malformation

The incidence of diastematomyelia associated with teratoma is extremely rare. We present a case of sacrococcygeal teratoma in a neonate with split spinal cord malformation(SSCM). Magnetic resonance imaging(MRI) showed a heterogenous mass lesion with cyst in the sacrococcygeal region and multiple spinal anormalies (diastematomyelia, tethered cord, hydromyelia, and hemivertebrae). The mature teratoma was confirmed on histopathological examination. In SSCMs, the potential for coexisting congenital anomalies at separate levels of the spinal cord must be considered in radiological investigations.
