The most prevalent thoracic spine disc-related findings are degeneration and herniation. Disc herniations predominate in the lower segments and are a dynamic phenomenon. Disc degeneration can be rapidly evolving but tends to remain unchanged after occurrence. Endplate marrow signal changes were an uncommon manifestation of thoracic disc disease. Schmorl nodes showed the least change over time.
We report a case of a 55-year-old woman with chronic renal failure and secondary tumoral calcinosis with rare intraosseous penetration of the humerus. Typical lobulated calcifications with associated layering “milk of calcium” were present about the right shoulder and elbow on conventional radiographs, computed tomography images and magnetic resonance images. Rare appearance of cortical destruction and intraosseous extension of tumoral calcinosis into the medullary space was observed in the proximal humerus on CT and MR images. Since there is concern for pathologic fracture, radiologists should be aware of this rare complication of chronic renal disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
