[FGD PET in a patient with pseudofractures from osteomalacia]

We present the case of a 42 year old man, with a history of multiple fractures and generalized pain for two years. A three phase bone scan, demonstrated multiple fractures involving the ribs, both ankles and feet. After going through a battery of tests which included an FDG PET scan (to exclude an occult malignancy), the patient was diagnosed with osteomalacia and hyperparathyroidism. The FDG PET scan, demonstrated multiple foci of increased FDG uptake throughout the axial skeleton, in a pattern highly suggestive of pseudofractures, rather than osseous metastases.
