A case of osteosarcoma with calcific mediastinal lymphadenopathy is presented. The lesion caused increasing dysphagia and bronchial erosion, showed uptake of isotope on a bone scan and was seen to enlarge on follow-up CT scans.
A case of metastatic Ewing's sarcoma to the skull is presented, demonstrating the superiority of magnetic resonance imaging over other imaging modalities to exclude CNS involvement. Precise delineation of different tumor components in extradural location contained in an intact dural rim together with compressed cortex showing no signs of tumorous involvement constituted a MRI appearance allowing us to exclude tumor outgrowth into the brain.
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.
