This image was made up of several layers of stone combined to give the impression of violent movement around a fixed central mass – like a rock set in a stormy sea.
It was inspired by a man who presented with a cough following a bout of flu. There was no evidence of pneumonia on his Chest X-ray but several large calcified lumps in his lungs were incidentally found. These look alarming but were actually benign malformation in the way the lung was made. These are known as hamartomas. They grow at the same rate as the body but as a disorganised mass made up of tissues arising from the organ that they lie in. The bronchi of the lung contain cartilage in the walls which can calcify. The calcium seen in these lumps arises from its cartilage component and classically look like popcorn on the X-ray. They are sometimes known as “lung stones”.
