CT of the thorax –
Both pleural cavities present a mild amount of non-contrast enhancing gravity dependent uniformly soft tissue attenuating fluid. The generalized retraction and cortication of the lung and pleural thickening has progressed. The lung presents with multiple surface retractions associated with pleura-based interstitial bands emerging from the visceral pleura (pleural and interstitial scarring). The pleura is markedly thickened and presents mildly irregular with multifocal small mineralized foci. The sternal and cranial mediastinal lymph nodes are moderately enlarged with maintained short to long axis ratio of < 0.5.
