A woman in her 50s who initially presented with movement disorder was diagnosed with aceruloplasminemia, a rare autosomal recessive disorder resulting in accumulation of iron deposits in major organs. Genetic testing confirmed mutations in the ceruloplasmin gene (c.1864 + 1G>C). Dilated fundus examination disclosed multiple dark pigmentary lesions at the temporal periphery, sparing the macula (Figure, A). Fluorescein angiography revealed corresponding discrete retinal pigment epithelium transmission hyperfluorescence. Optical coherence tomography revealed presumed iron deposits at the retinal pigment epithelium level (Figure, B). Brain and liver magnetic resonance imaging showed diffuse iron deposition. Treatment options include iron chelation, fresh frozen plasma transfusion, and vitamin E intake.
