A case of bone marrow necrosis and fat embolism in a sickle-cell disease patient

: We report here a case of bone marrow necrosis and fat embolism syndrome in a 23-year-old sickle-cell disease (HbSS) patient. A brutal and severe bicytopenia conducted to suspect bone marrow necrosis, confirmed by bone marrow aspiration and analysis. This was the first life-threatening medical event for this patient. In the present case, a complex alloimmunization against blood group antigens complicated the treatment because of the risks associated with the transfusion strategy. These rare complications of sickle-cell disease may be fatal, but an efficient symptomatic treatment generally allows for recovery. Medical biologists should be aware of the danger of bone marrow necrosis in sickle-cell disease, so that they can help clinicians and accurately diagnose this serious complication.
