Hyperthyroidism

Case Description:

This is the baseline Hologic DXA scan from a postmenopausal woman referred to Osteoporosis Clinic with low bone mineral density. The accompanying note from the referring endocrinologist indicated that her thyroid replacement dose had been five-times the dose that was required to make her euthyroid for the past several years. Hyperthyroidism is a secondary cause of low bone mass.
