Intramedullary immature teratoma in a young infant involving a long segment of the spinal cord.
Intramedullary teratoma is a rare lesion, located in the majority of cases in the lumbosacral area, and such lesions involving an extensive area of the spinal cord in young infants have seldom been reported. We present the case of a 3-month-old girl with an intramedullary spinal immature teratoma extending from C-5 to T-12, which was totally removed. The patient had suffered from paraplegia for 15 days, after which spinal MRI revealed a heterogeneously enhancing intramedullary lesion. Biopsy of the lesion demonstrated mature intestinal tissue. After total removal of the tumor, paraplegia and sphincter disturbances improved. Intramedullary teratoma should be included in the differential diagnosis of holocord tumors in young infants with rapidly progressing symptoms and if found should be radically excised. This case also emphasizes the importance of histological diagnosis and demonstrates the possibility of neurological recovery even in the case of paraplegia lasting for more than 1 month in a young infant.
