The CT scan of the centrally positioned small cell carcinoma has structural implication as a result of its central location close to large arteries, veins, airways and lymphatics. In this case the centrally placed tumor (dark green in image b) is pushing on the right mainstem bronchus (shown with white arrow) and the lymphatics with peribronchial thickening (image d light green) and extension into the interlobular septa (bright green in d) Subcarinal nodal involvement and left hilar involvement (light green in b)together with small right effusion (a,b) are also noted suggesting advanced disease.

CT in the axial plane demonstrates a large, spiculated mass in the right upper lobe likely reflecting hemorrhage around the mass. In addition there is evidence of interlobular septal thickening, and secondary changes in the right major fissure possibly reflecting lymphatic invasion and raising the possibility of lymphangitis carcinomatosis

This collage of CT and plain film represents the radiological history of a patient with poorly differentiated small cell carcinoma, with extensive parenchymal involvement of the RUL and RML, and of the airways of RML and RLL. Images 1 and 2 show an interstitial and pneumonic pattern which was persistent over time. The CT shows extensive endobronchial disease involving right main stem (3,4) as well as almost all segments of RLL. This was confirmed by bronchoscopy.
Lymphangitic disease seems to be the dominant finding in the RUL on the lung windows. (5).
Following stent placement through a ?pinhole? lesion, the patient occluded the RUL airways with tracheal shift and hyperinflation of the left lung (6,7,8,9). Clinically however, she improved greatly.
