Summary
A rare case of unilateral retinoblastoma in a 13-month-old boy mimicked orbital cellulitis. Ultrasonography identified the mass after CT failed, highlighting imaging importance in pediatric eye conditions.
Area of Science:
- Ophthalmology
- Pediatric Oncology
- Medical Imaging
Background:
- Orbital cellulitis in children requires prompt diagnosis to differentiate from intraocular pathology.
- Retinoblastoma, a common pediatric eye cancer, can present with varied clinical signs.
Observation:
- A 13-month-old boy presented with unilateral orbital cellulitis, heterochromia, hyphema, and vitreous hemorrhage.
- Initial computed tomography (CT) imaging did not detect an intraocular mass.
- Ocular ultrasonography successfully identified a calcified intraocular mass.
Findings:
- Histopathology of the enucleated eye showed inflammation and tumor necrosis, but no viable retinoblastoma cells.
- Genetic testing results were inconclusive.
- The patient is presumed to have had retinoblastoma with spontaneous autoinfarction.
Implications:
- This case underscores the critical role of comprehensive ocular evaluation in pediatric orbital cellulitis.
- It emphasizes the diagnostic utility of ultrasonography when CT imaging is inconclusive for intraocular calcifications.
- Accurate imaging modalities are crucial for diagnosing retinoblastoma and guiding appropriate management in young children.

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
