Imaging in Sternal Tumours: A Pictorial Review - PMC - PubMed …
CT shows a lytic, expansile lesion causing cortical ballooning and thinning with associated enhancing soft tissue component attributed to its high vascularity. Other neoplasms, that may show direct sternal invasion, include mediastinal tumours such as thymic malignancies, lymphomas, etc. [ 1 , 2 , 4 , 12 , 13 ].
Lucent Lesions of Bone | UW Radiology - University of Washington
Most expansile, lucent lesions are located in the medullary space of the bone. However, we can further define the location of the lesion by noting its relationship to the physis. Many lesions tend to occur in a “favorite” part of the bone.
Radiology of Chest Wall Masses - AJR
The axial CT image in bone window shows that the lesion is expansile, with fine bony spicules radiating from the central portion and loss of the normal cortical rib margins . The mass exhibits high signal on T2-weighted imaging with fat suppression with lower signal in the central portion of the lesion ( Fig. 7C ).
