Sterile subperiosteal fluid collections accompanying orbital wall infarction in sickle-cell disease.

Infarction of the orbital wall is an uncommon manifestation of sickle cell disease (SCD) that may mimic an infectious process. We report a patient with two separate orbital infarctions with different presenting symptoms involving different bones. Radiologic-guided sampling of a periosteal fluid collection in the first episode showed likely sterile inflammatory exudates. This case highlights the range of findings in orbital wall infarction in SCD as well as helpful clinical and imaging entities that may differentiate infarction from infection, allowing early diagnosis and appropriate management.
