Insights

A rare intramedullary immature teratoma was found in a 3-month-old infant, extending over a large spinal cord area. Complete surgical removal led to significant neurological recovery, highlighting early diagnosis and intervention for holocord tumors.

Area of Science:

  • Pediatric Neurosurgery
  • Spinal Cord Oncology
  • Developmental Pathology

Background:

  • Intramedullary teratomas are rare spinal cord tumors, typically found in the lumbosacral region.
  • Extensive holocord intramedullary teratomas in young infants are exceptionally uncommon.

Observation:

  • A 3-month-old infant presented with paraplegia and sphincter disturbances.
  • Spinal MRI revealed a large, heterogeneously enhancing intramedullary lesion from C-5 to T-12.
  • Histological examination of the tumor biopsy confirmed mature intestinal tissue, indicative of teratoma.

Findings:

  • The immature teratoma was surgically excised completely.
  • Post-operative improvement in paraplegia and sphincter function was observed.
  • Neurological recovery was possible despite a 1-month history of paraplegia.

Implications:

  • Intramedullary teratoma must be considered in the differential diagnosis of holocord tumors in infants with rapid neurological decline.
  • Radical surgical excision is the recommended treatment for intramedullary teratomas.
  • Early histological diagnosis and prompt surgical intervention can lead to favorable neurological outcomes, even in severe cases.
