Chest 152; Chest stones
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”.
Chest X-ray 151
Chest X-ray 151A
These two pictures are essentially the same picture with different processing within Photoshop allowing more or less of the background to shine through the X-ray.
The X-ray is from a man with pneumocystis pneumonia – an organism that invades the body of immune compromised people, especially HIV.
I have difficulty deciding which is the more interesting, and more relevant picture and therefore have posted both, it would be good to hear peoples comments on these.
Once again a set of six images from the local Agricultural Show this weekend. I continue my theme of black and white with a touch of colour, but in line with helpful comments on the previous sets, this group is more cropped, and the colour is generally more subtle.
Mother and child
The base image for this picture was a piece of Sellotape attached many years before to the wall, the tape had fallen off leaving a squarish patch of adhesive still stuck to the paint, yellowed with age. I have tried to indicate the pieces as fragmenting and becoming unstuck.
I have paired this with the X-ray of a child with a mycoplasma pneumonia. This is caused by a very small bacterial organism that, when it is breathed in, attaches to the surface cells of the bronchi.
The ability of a bacterium to invade and colonise a host depends on the ability to withstand the host’s mechanical and immunological defences. The power to invade depends on the bacterial capability to quickly and effectively attach to the host cells and avoid being expelled. Most bacteria that either live in, or infect a host make special adhesive molecules on their surfaces that interact with host cells causing the bacteria to adhere to the surface with great strength. The attachment uses extremely sticky protein glue known as an adhesin. The process of attachment is complex involving a series of processes which if disrupted interrupts the infection. One mechanism by which antibiotics work is to break down, or inhibit production of these adhesins and this allows the bacteria to be expelled from the body.
As part of the series on geometrical shapes this is the Cross.
The crosses were part of a jetty seen on the ferry trip up Charlotte Sound in BC Canada. Images were superimposed and sparingly coloured. I liked the reflections in the water.
They have been teamed with the chest X-ray of a man with Sarcoidosis. This is a disease of unknown cause – so called idiopathic – in 90% of cases granulomas form in the lungs and frequently multiple other parts of the body including bones. The main sign on a chest X-ray is enlarged lymph nodes around the heart and centre of the chest, but later if the disease progresses a fine criss-crossing pattern known as a reticular interstitial pattern can develop. This can further progress to form a honeycomb pattern, though this is rare.
At least half of these cases resolve spontaneously or with minimal treatment, and most resolve within five years. Though a few go on to have long term chronic disease.
This is one of the geometric shapes series.
The colours in this image have a remarkably Christmassy feeling. The base images were taken from the candle-lit sparkles on polished cut glass bringing out the square pattern on the surface. The chest X-ray is from a man with emphysema with the classic box-shaped chest.
Despite the happiness in this image, there are two slightly ominous aspects; the highlit cross in the middle reminds me of a distorted plane flying over the ground, and the bones clearly visible on the right are distinctly un-Christmassy.
