Abstract
Bone marrow necrosis (BMN) is a rare finding in children with malignancy occurring most commonly in children with acute lymphoblastic leukemia. This article describes the first case of a girl who developed BMN during treatment for Hodgkin's disease. During the second cycle of chemotherapy, she experienced sudden profound bone pain in the lumbosacral region associated with elevated levels of lactate dehydrogenase (LDH), fibrin degradation products (D-Dimer), and alkaline phosphatase as well as pancytopenia and leukoerythroblastosis. MRI studies showed multiple confluent areas with low signal intensity and rim contrast enhancement in all vertebral bodies. Bone marrow biopsy revealed focal necrosis within hypocellular bone marrow. The patient responded quickly to symptomatic treatment with analgetics and heparin; however, elevations of LDH and D-Dimer persisted for 1.5 and 8 months, respectively. Clinicians should be aware of this rare condition to establish the diagnosis and to continue oncologic treatment as early as possible.
