The frontal chest radiograph shows two to three nodular soft tissue opacities in the left mid zone and lower zone. The rest of the left lung is hyperinflated. There is a moderate sized pleural effusion on the right side. The HRCT of the chest shows consolidation with adjacent centrilobular nodules in the left lung. There is right pleural effusion with a relatively homogeneous soft tissue opacity along the right apical pleura extending into the neck and the anterior chest wall. There is encasement of vessels without luminal narrowing. There are multiple enlarged lymph nodes in the right axilla. On MRI, the lesion is T2 hypointense, homogeneously enhancing with diffusion restriction. There is extension into the spinal canal compressing the cord.
A Pancoast tumor is named after Henry Khunrath Pancoast (1875–1939), a pioneering American radiologist. He was the first Professor of radiology in the United States, based at the University of Pennsylvania. He first described this specific type of apical lung cancer in 1924.
