Diffuse infiltrating retinoblastoma presents atypically, often mimicking posterior uveitis. Diagnostic imaging is limited, frequently necessitating anterior chamber paracentesis for accurate diagnosis.

Area of Science:

  • Ophthalmology
  • Pediatric Oncology
  • Medical Imaging

Background:

  • Diffuse infiltrating retinoblastoma is a rare variant of retinoblastoma.
  • It often presents with atypical signs, mimicking other intraocular conditions like posterior uveitis.
  • Early and accurate diagnosis is crucial for effective treatment and preserving vision.

Observation:

  • Two pediatric cases with atypical posterior uveitis were diagnosed with diffuse infiltrating retinoblastoma.
  • A review included these two cases and 26 previously published cases.
  • Epidemiology, presenting signs, and diagnostic test utility were assessed.

Findings:

  • Histologic analysis revealed calcification in only 4 of 28 infiltrating lesions, unlike typical retinoblastoma.
  • Computed tomography (CT) scans and ultrasonography showed limited diagnostic value.

  • Anterior chamber paracentesis was often required to confirm the diagnosis.

    • Implications:

    • The findings highlight the diagnostic challenges associated with diffuse infiltrating retinoblastoma.
    • A systematic diagnostic approach is proposed for this rare condition.
    • Improved diagnostic strategies are needed to differentiate it from other uveitic entities.
