This study reports on a child with unilateral hyphema who was diagnosed with diffuse infiltrating retinoblastoma. Computed tomography revealed characteristic calcifications, aiding in the diagnosis of this rare eye cancer.

Area of Science:

  • Ophthalmology
  • Pediatric Oncology
  • Medical Imaging

Background:

  • Unilateral hyphema in children can present diagnostic challenges, sometimes obscuring underlying conditions.
  • Diffuse infiltrating retinoblastoma is a rare variant of retinoblastoma, often presenting atypically.
  • Early and accurate diagnosis is crucial for effective management and improved outcomes in pediatric eye cancers.

Observation:

  • A child presented with a month-long unilateral hyphema and a history of possible blunt trauma.
  • Initial ultrasonography did not reveal any tumefaction.
  • Ocular media clearing over two months revealed a diffusely abnormal retina.

Findings:

  • Computed tomography (CT) demonstrated a diffusely thickened posterior pole with calcifications.

  • Histopathological examination of the enucleated globe confirmed diffuse infiltrating retinoblastoma.
  • This case represents the first report detailing CT findings in diffuse infiltrating retinoblastoma.

    • Implications:

    • CT imaging can be a valuable tool in diagnosing diffuse infiltrating retinoblastoma, especially when other methods are inconclusive.
    • Recognizing the CT characteristics of this rare tumor can lead to earlier diagnosis and treatment.
    • This finding contributes to the understanding of rare pediatric eye tumors and their imaging features.
