Retinoblastoma Presented Unusually as Orbital Cellulitis, Spontaneous Hyphema, and Dislocated Lens-A Case Report

Abstract

A 4-year-old boy demonstrated as severe orbital cellulitis and total hyphema of his left eye after a minor head injury. An intra-ocular tumor with calcification and lens dislocation were demonstrated by orbital CT and MRI. Retinoblastoma with massive tumor necrosis was proved by pathology after enucleation. Retinoblastoma with subluxated lens had rarely been reported in the literature. Orbital swelling mimicking orbital cellulitis is also an uncommon presentation of retinoblastoma, and it does not necessarily indicate extrascleral extension of tumor.
