Summary
This case report highlights diffuse retinoblastoma, a rare eye cancer. Early diagnosis relies on characteristic clinical signs and diagnostic tests, with enucleation as the primary treatment.
Area of Science:
- Ophthalmology
- Pediatric Oncology
- Medical Diagnostics
Background:
- Diffuse retinoblastoma is a rare intraocular malignancy.
- Late-onset retinoblastoma can mimic uveitis, complicating diagnosis.
- Prompt diagnosis is crucial for effective management.
Observation:
- A 6-year-old boy presented with a diffuse retinoblastoma.
- Clinical signs included Tyndall phenomenon, pseudo-hypopyon, iris nodules, and a non-calcified retinal mass.
- Ultrasonography revealed an imprecisely limited peripheral retinal mass.
Findings:
- Aqueous paracentesis demonstrated elevated Lactic Dehydrogenase (LDH) levels.
- Cytologic examination confirmed the diagnosis of retinoblastoma.
- The clinical presentation mimicked uveitis due to the late onset.
Implications:
- This case underscores the importance of recognizing subtle clinical signs of retinoblastoma.
- Diagnostic paracentesis and cytology are vital for confirming suspected cases.
- Enucleation remains the standard treatment for diffuse retinoblastoma.
