Abstract
An 11-year-old boy presented with a femur fracture, bone hypomineralization, and hypophosphatemia, suggesting tumor-induced rickets. Conventional radiologic techniques including magnetic resonance skeletal survey did not identify a tumor. Magnetic resonance gradient echo recall imaging demonstrated a 3-cm iliac tumor, the resection of which rapidly reversed metabolic abnormalities. This technique may be useful in identifying elusive tumors associated with tumor-induced rickets.
