Figure 2: (a and b) MRI of the chest revealed large right apical superior sulcus pulmonary mass likely primary bronchogenic carcinoma with extensive local spread of disease to the adjacent soft tissues and involving the right brachial plexus nerve roots exiting the upper thoracic spine (arrows), and is most prominent posteriorly involving and surrounding the proximal first and second ribs, spinous transverse processes (arrow heads). (c and d) Histopathology characteristic of non-small cell lung carcinoma (NSCLC). Infiltrating nests of cohesive cells containing enlarged hyperchromatic nuclei, moderately abundant eosinophilic cytoplasm in collagenous stroma (arrows). A: Staining with hematoxylin-eosin, magnification ×200. B: Staining with hematoxylin-eosin, magnification ×400
