Summary

Orbital teratomas are rare, fast-growing tumors. This case highlights a late-presenting orbital teratoma in a child with normal vision, demonstrating successful surgical removal and vision preservation.

Area of Science:

  • Ophthalmology
  • Pediatric Oncology
  • Surgical Pathology

Background:

  • Orbital teratomas are uncommon, aggressive tumors typically presenting at birth with proptosis.
  • Congenital orbital teratomas often lead to poor visual outcomes due to rapid growth and optic nerve compression.

Observation:

  • An 18-month-old child presented with an inferior orbital mass, normal visual acuity, and intermittent hypertropia.
  • Imaging revealed a cystic mass with a tooth near the inferior orbital fissure.
  • Histopathological examination confirmed a teratoma with derivatives from all three germ layers.

Findings:

  • Surgical excision of the orbital teratoma was successfully performed.
  • The patient experienced preservation of vision post-operatively.

  • Intermittent hypertropia resolved following tumor removal.

    • Implications:

    • This case demonstrates that orbital teratomas can present later in infancy with favorable visual outcomes.
    • Early diagnosis and surgical intervention are crucial for preserving vision in pediatric orbital tumors.
    • Late presentation with good visual prognosis is exceptional for orbital teratomas, challenging typical clinical expectations.
