Progressive Diffuse Osteonecrosis in a Patient with Secondary Hemophagocytic Lymphohistiocytosis

Figure 1

Coronal reconstruction CT in bone window at the time of admission to the outside institution shows essentially normal bone marrow other than some Schmorl’s nodes. Note additional findings of splenomegaly and left basilar consolidation/atelectasis. Focus of hypoattenuation in the spleen () was interpreted as a focus of splenic infarction. Also note that there is no evidence of osteonecrosis in either hip.
