 We report the case of a patient with spinal immature teratoma and cerebrospinal fluid leakage from the congenital dermal sinus tract. A 0-day-old female infant presented with a subcutaneous soft mass with a dimple in the lumbosacral region at birth. Magnetic resonance imaging revealed a mixed low-intensity mass located in the extraspinal and intraspinal canal with a sinus tract. The reconstructed three-dimensional spinal computed tomography image showed spina bifida and ectopic ossification at the dorsal aspect of the sacrum. Urgent removal of the tumor and dermal sinus tract was then performed under evoked electromyography monitoring. The resected tumor was histopathologically diagnosed as immature teratoma.
