Summary

A rare suprasellar germinoma with cystic components was diagnosed in a 13-year-old girl. Multimodal treatment achieved complete remission, with minor residual endocrine issues.

Area of Science:

  • Neuro-oncology
  • Pediatric Endocrinology

Background:

  • Germinomas are rare intracranial tumors, often occurring in the suprasellar region.
  • Suprasellar tumors can present with visual disturbances and endocrine dysfunction due to proximity to critical structures.

Observation:

  • A 13-year-old female presented with visual acuity deficits and growth retardation.
  • Radiographic imaging revealed a suprasellar mass with extensive cystic components, posing diagnostic challenges.
  • Histopathological confirmation identified the tumor as a germinoma.

Findings:

  • The patient underwent a multimodal treatment approach including surgery, chemotherapy (carboplatin and etoposide), and radiotherapy (30 Gy).
  • This comprehensive treatment resulted in complete tumor remission.
  • Post-treatment endocrine evaluation revealed normal status except for low growth hormone (GH) concentration and diabetes insipidus.

Implications:

  • This case highlights the importance of considering germinoma in the differential diagnosis of suprasellar masses, even with atypical radiographic features.
  • Multimodal therapy is effective for achieving remission in pediatric suprasellar germinomas.
  • Long-term endocrine surveillance and management are crucial for patients treated for suprasellar germinomas.
