Abstract:
Osteosarcomas generally arise in appendicular skeletons, but rarely in the ribs. We described Tc-MDP bone scan findings from a 23-year-old man with right back pain. The images demonstrated elevated activity in the region overlapping the posterior 8th to 10th ribs and in the L9-10 vertebral bodies. CT showed an 8.8 × 8.3 cm mildly peripherally calcified mass arising from the right 10th rib involving the 9th and 10th thoracic vertebrae. Pathological examination confirmed primary osteosarcoma of the rib.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
