Abstract: A previously healthy 8-year-old girl underwent MDP bone scintigraphy to evaluate possible spondylolysis due to worsening back pain. Unexpectedly, the bone scan images revealed intense activity in several thoracic and lumbar vertebrae, which was not consistent with spondylolysis. Further examinations proved that the patient had acute lymphocytic leukemia.
