Identifying and Treating Severe Bone Marrow Necrosis and Fat Embolism Syndrome in Pediatric Patients With Sickle Cell Disease: A Case Report.

Fat embolism syndrome after bone marrow necrosis is an extremely rare complication in sickle cell disease associated with significant morbidity and mortality. A high index of suspicion is required for diagnosis. This case report will assist pediatric clinicians and hematologists to recognize this severe complication in patients with sickle cell disease and to promptly initiate treatment. Red flags include severe bone pain, respiratory distress, neurological impairment, decreasing platelet count, peripheral leukocyte left shift, elevated nucleated red blood cells, and significant elevation in plasma ferritin and lactate dehydrogenase. We report a pediatric patient who was diagnosed early, received urgent red cell exchange transfusion and plasma exchange, and ultimately survived this devastating complication.
