Intraocular mass simulating a retained foreign body.
PURPOSE: To present an unusual case of a preretinal mass that simulated a retained metallic foreign body. METHOD: Case report. RESULTS: A 30-year-old man presented with unilateral iridocyclitis and an ipsilateral preretinal mass with ultrasonographic and computed tomographic characteristics of a metallic foreign body. Histologic examination of the mass disclosed a central concentration of iron-containing hemoglobin breakdown products surrounded by a cocoon of fibrous tissue. CONCLUSION: Blood breakdown products surrounded by a fibrous capsule can present with the characteristics of an intraocular metallic foreign body.
