• Two cases of unilateral and bilateral periorbital hematomas occurred in patients with sickle cell anemia. The cause of periorbital swelling in these cases was found to be orbital and frontal bone infarctions, respectively, diagnosed by technetium Tc 99m medronate bone scintigraphy. To our knowledge, periorbital bone infarction, as a part of the differential diagnosis of periorbital hematoma and as part of the possible ocular manifestations in patients with sickle cell anemia, has not previously been described.
