We report on a case of malignant lymphoma in the chest wall, associate
d with chronic tuberculous empyema. CT and MR imaging showed a soft-ti
ssue mass contiguous with the empyema and invading the chest wall. MR
imaging demonstrated a difference in signal intensity between the mass
and the empyema. The extent of the chest-wall lymphoma was optimally
delineated on fat-suppressed contrast-enhanced MR images.
