Case 50 Diagnosis

Choroidal osteoma

Differential Diagnosis

  • Amelanotic choroidal nevus: benign flat yellow/orange lesion, asymptomatic. These lesions are also not typically associated with retinal pigment epithelial atrophy.
  • Amelanotic choroidal melanoma: elevated, yellow/brown lesion, often diagnosed in the sixth decade of life. Rarely bilateral.
  • Choroidal metastatic carcinoma: elevated, yellow lesion often associated with a serous retinal detachment; often associated with history of lung, breast, gastro-intestinal, and other primary carcinoma. Ultrasound would not show such extensive “shadowing” by the lesion.
  • Circumscribed choroidal hemangioma: sessile or dome-shaped, yellow/orange lesion, typically detected in third decade of life
