Summary

A young boy initially treated for chorioretinitis experienced a relapse, later presenting with a large tumor suspected to be choroidal melanoma. Histological diagnosis revealed an unusual ectopic meningioma-like lesion.

Area of Science:

  • Ophthalmology
  • Pathology
  • Oncology

Background:

  • A 15-year-old male presented with central chorioretinitis in his right eye.
  • The condition relapsed two years later, causing decreased visual acuity.

Observation:

  • Clinical and fluorescein angiography findings initially suggested an inflammatory process.
  • After a six-year interval, the patient returned with severe eye pain, a blind, inflamed eye, and a large tumor involving the optic nerve and extending peripherally.

Findings:

  • Imaging studies (ultrasonography, CT, MRI) indicated a choroidal melanoma with extrabulbar extension.
  • Histopathological examination revealed a rare ectopic meningioma-like lesion, distinct from the initial inflammatory diagnosis.

Implications:

  • This case highlights the importance of considering rare tumorous lesions mimicking inflammatory conditions in ophthalmology.
  • The diagnostic challenge underscores the need for comprehensive histopathological evaluation in complex ocular cases.
  • Understanding such rare entities is crucial for accurate diagnosis and management of potentially vision-threatening conditions.
