A case of bilateral retinoblastoma with left orbital cellulitis.

摘要

A 5-month-old boy was referred to our hospital for the treatment of left eyelid swelling and leukocoria. His left eyelid was swollen and could not be opened by himself. The conjunctiva was also swollen, and the cornea was clouded because oi increased intraocular pressure. Orbital CT scan demonstrated a left intraocular tumor with calcification, periocular high-intensity area (anterior orbital cellulitis) and deformed eyeball (Fig. 1). The intraocular tumor showed low signal intensity on T2-weighted image. His right eye had three small retinal tumors, and the clinical diagnosis was bilateral retinoblastoma. His left eye was enucleated, and the pathological examination revealed retinoblastoma with calcification and extensive necrosis, however, without extraocular extension (Fig. 2; note that a color version of this figure is available as supplementary data ai http://www.jjco.oxfordjournals.org). He underwent no systemic chemotherapy, but only selective ophthalmic arterial injectior for the right eye.
