ORBITAL WALL INFARCTION IN SICKLE-CELL DISEASE - MR EVALUATION

Orbital wall infarction in a patient with sickle cell disease can pres ent with periorbital swelling and subperiosteal collection and thus ca n mimic infection on CT. However, MR not only provides excellent morph ologic information but, by characterizing the nature of the collection as containing blood, and by identifying bone marrow abnormality, can lead to the diagnosis of orbital wall infarction.
