title: Vertebral compression and eosinophilia in a child with acute lymphatic leukemia.
abstract: A 10-year-old girl, presenting with fever, eosinophilia, and back pain, was diagnosed with pre-B CD10-positive acute lymphoblastic leukemia. Eosinophilia resolved rapidly during remission induction treatment, but diffuse spinal osteopenia with multiple compression fractures became manifest after 4 weeks. During subsequent treatment the spine remineralized slowly, and after 26 months vertebral bone regeneration was apparent. Eosinophilia and osteopenia are separately known as early manifestations of acute lymphoblastic leukemia, but their simultaneous occurrence is particularly interesting. A late bone marrow relapse was not accompanied by bone changes or eosinophilia.
