Abstract

|
|
A 84-year-old woman visited by back and pubic pain. Abdominal CT showed 10cm sized abdominal mass with calcified
component. At bone scan, multiple bone absorption was seen. T2 weighted MRI revealed heterogeneous high signal mass on pubis. Aspiration cytology reported only blood and exudate without malignant cells. Other 88-year-woman visited by systemic arthralgia and dysbasia. Abdominal CT revealed pubic bone fracture, surrounded by soft tissue, and relatively low density on lumbar spine. Bone scan showed increased absorption at multiple bone and joints. Enhanced chest CT revealed only consolidation, no malignant component was seen. Aspiration cytology reported degenerative bone tissue without malignant cell. At these cases, mass like lesion was looked like malignant tumors, but final diagnosis was insufficiency fractures. Aware these cases, we emphasize avoid misunderstanding for malignancy, may read to unnecessary and excessive evaluation before making the correct diagnosis, at insufficiency fracture.
