title: Solitary plasmacytoma of the sternum: diagnosis by computed tomography.
abstract: We report a large solitary plasmacytoma arising in the sternum of a 62-year-old man. On computed tomography the tumor demonstrated a multilobular appearance associated with bone destruction and expansion and absence of intrinsic calcification. Computed tomography was helpful in determining the size and extent of the tumor and in suggesting the correct diagnosis.
