Osteosarcoma L3 LSBU

Description: Radiology case 332-3221 20 year old male with back pain.
The view is from an intravenous urogram, which shows normal pelvicalyceal systems and ureters. There is increased density on the right side of the 3rd lumbar vertebra. The density overlies the body, but also lies outside the vertebra. It is responsible for the elvation of the blurred right side of the upper end-plate. The centre of radius of the lesion is roughly the blurred and sclerotic right lateral cortical margin. There is some bone destruction of the lateral margin of the upper end plate of L3.
