Vanishing bone disease involving the pelvis

Vanishing bone disease is a rare condition characterized by progressive osteolysis of the bony structures by vascular tissue and their replacement by fibrous, vascular connective tissue. A 38-year-old lady who had a previous history of angioma of the left iliac bone presented with vague symptoms of a limping gait and pain during walking since 2 years duration. The radiologic findings were suggestive of degenerative changes. A possibility of metastatic disease was also considered. However the biopsy and Positron emission tomography (PET) scan ruled out any active disease. Like in most other cases this was possibly a self-limited disease where bone resorption had spontaneously arrested.
