A case of regional migratory osteoporosis.

Abstract

We present the case of a middle-aged man with three episodes of regional migratory osteoporosis of the lower extremities occurring over a period of 8 years. Symptoms included a sudden onset of unilateral bone and joint pain. After initiation of pamidronate treatment, symptoms improved significantly. Regional migratory osteoporosis is a rare, but probably underdiagnosed condition with an unclear etiology. This case illustrates the importance of recognition of the disease in order to inform the patient, start treatment, and prevent unnecessary invasive procedures. Although in literature, not much is reported about treatment strategies, our patient was successfully treated with pamidronate after failure of oral bisphosphonates.
