Multiple anterior and posterior chamber pseudocysts in a 12-year-old boy with diffuse infiltrating retinoblastoma.
Diffuse infiltrating retinoblastoma is a rare subtype, occurring in 1% of all patients with retinoblastoma. It usually presents with pseudoinflammatory response in the anterior chamber and the vitreous, masquerading as endophthalmitis or uveitis. This report describes a 12-year-old boy with multiple free-floating intraocular pseudocysts as a unique finding in diffuse infiltrating retinoblastoma. These pseudocysts represent necrotic seeds without epithelial lining. Invasive surgical procedures should be avoided in children presenting with atypical, chronic, unilateral intraocular inflammation of unknown cause until retinoblastoma is excluded.
