Bone scintigraphic patterns in patients of tumor induced osteomalacia
A 34-year-old female presented with progressive weakness in proximal muscles. Her biochemical profile revealed low phosphorus, elevated FGF23 level (147.9 RU/ml) and the rest were within the normal limits. She was diagnosed to be suffering with severe hypophosphatemic osteomalacia. Whole body bone scan showed increased tracer uptake in bilateral maxillary bone, bilateral shoulder, wrist, sternoclavicular, knee and ankle joints, multiple ribs and mid shaft of bilateral femora []. The tumor was localized on functional imaging. It was resected out with histopathology report consistent of mesenchymal tumor and resulting in significant relief of symptoms post-operatively.
