Contrast-enhanced axial CT scan reconstruction in the bone window (a), axial T2WI (b) and axial contrast-enhanced T1WI (c) show well-defined, bilateral hypaxial masses (arrows). Sagittal T1WI demonstrates multiple hypaxial masses (arrows) (d). Axial CT scan reconstruction (a) shows widened ribs and osteosclerosis of the vertebraBack to article page
