Bilateral iliac metastases with sunburst pattern from prostate cancer

Bone metastases from prostatic carcinoma commonly exhibit blastic characteristics with radiographically dense lesions. Occasionally they may demonstrate an unusual pattern of spiculation mimicking primary neoplasms of sarcomatous origin. The author presents a case of bone metastases from prostate carcinoma with bilateral and relatively symmetric iliac "sunburst" lesions documented on computed tomography and bone scintigraphy.
