Correct!
4. The thoracic CT shows a right-sided perihilar soft tissue mass associated with mediastinal lymph node enlargement and right pleural thickening
Thoracic CT shows a large right-sided mass with extensive mediastinal contact and compression of the right pulmonary arteries and veins. Multifocal mediastinal lymph node enlargement is also evident. The right paramediastinal mass shows foci of calcification (Figure 3).
Figure 3. Contrast-enhanced thoracic CT shows a large right-sided mass with extensive mediastinal contact and compression of the right pulmonary arteries and veins. Multifocal mediastinal lymph node enlargement (arrowheads, B, E, and F) is also evident. The right paramediastinal mass shows foci of calcification. The mass compresses and narrows the right lower lobe bronchus (arrows, C and D), resulting in the right lung volume loss noted at chest radiography.
The mediastinal lymph node enlargement is unilateral, not bilateral. While circumferential pleural thickening is present, the findings should not be described as a “multilobulated pleural space mass”, and no pleural liquid is present. No dominant anterior mediastinal mass is present. No evidence of a chest wall mass is seen.
Clinical course: The patient subsequently underwent 18FDG-PET scanning (Figure 4) for further evaluation of the findings at thoracic CT.
