Pneumothorax, sometimes abbreviated to PT, (plural: pneumothoraces) refers to the presence of gas (often air) in the pleural space. When this collection of gas is constantly enlarging with resulting compression of mediastinal structures, it can be life-threatening and is known as a tension pneumothorax (if no tension is present it is a simple pneumothorax).

An occult pneumothorax refers to one missed on initial imaging, usually a supine /semi erect chest radiograph 24. However, primary spontaneous pneumothoraces occur in younger patients (typically less than 35 years of age) whereas secondary spontaneous pneumothoraces occur in older patients (typically over 45 years of age) 4.

Presentation is variable and may range from no symptoms to severe dyspnea with tachycardia and hypotension. In patients who have a tension pneumothorax, presentation may be with distended neck veins and tracheal deviation, cardiac arrest and in the most severe cases, death.

Primary spontaneous: no underlying lung disease secondary spontaneous: underlying lung disease is present iatrogenic /traumatic Tall and thin people are more likely to develop a primary spontaneous pneumothorax.

Expiratory chest radiograph : lung becomes smaller and denser pneumothorax remains the same size and is thus more conspicuous: although some authors suggest that there is no difference in detection rate 6 Small pneumothoraces are best appreciated anteriorly in the supine position (gas rises) whereas large pneumothoraces are appreciated laterally in the mid-axillary line.

CT Provided lung windows are examined, a pneumothorax is very easily identified on CT, and should pose essentially no diagnostic difficulty. When bulbous disease is present, a loculated pneumothorax may appear similar.

Size of the pneumothorax symptoms background lung disease/respiratory reserve Estimating the size of pneumothorax is somewhat controversial with no international consensus.

If the pneumothorax measures <35 mm (measuring the largest air pocket between the parietal and visceral pleura perpendicular to the chest well on axial imaging) in stable, non-intubated patients there was a 10% failure rate (i.e. requiring intercostal catheter insertion) during the first week 16. This can either be medical (e.g. talc courage) or surgical (e.g. VATS neurectomy, pleural abrasion, sclerosis agent) 4.

History and etymology Pneumothorax is derived from two Greek words, (enemy) meaning breath and (thorax) meaning breastplate. The synonym, hemothorax, which is rarely, if ever, seen in modern medicine also has Greek roots, from (aero) meaning air 22,23.

Your instructor, Dr Julian Dobrzynski–an award-winning author and Professor of diagnostic imaging at McMaster University in Ontario, Canada–will guide you through the A-Z of chest X -rays. After watching this video, you will know how to search for and identify a pneumothorax.

The radiological pleura is abnormal if the pleural space becomes visible and the grayscale image is too black, too white, or too black and too white in combination. There are no vascular markings identified whatsoever in this region, but we can also identify the clear margin of the lung because we can identify the visceral pleura, as this thin line outlining the lateral aspect of the lung, in this region.

On an expiration film, the pneumothorax will be more evident because on expiration, there is less lung air, therefore, the lungs will look whiter, making the density difference between the pneumothorax and the lungs more evident, and the size of the pneumothorax will appear larger. as significant volume loss, within the left lung, on expiration.

The first step is to make sure that the patient is properly centered and is not rotated. Next, we look for asymmetry in the apical regions, knowing that the pneumothorax or the air within the pleural space will rise to the highest point.

In this case, we can identify that the right apical region is blacker than on the The next step, is to look for the edge of the lung and here, we can clearly identify a thin line, which represents the visceral pleura.

If you're still having difficulties identifying the pneumothorax, then outline each of the ribs, Between the 3rd and 4th rib, there is an additional line and this is the edge of the pneumothorax.

We see a large pneumothorax, which is causing collapse of the left lung and displacement of the mediastinal structures to the right. This is another example of a tension pneumothorax, with significant collapse of the right lung and mediastinal shift to the left.

overall volume loss within the lung and mild mediastinal shift to the right, consistent with early tension pneumothorax. In this case, the patient's had a previous pleural disease and has developed a pneumothorax.

Because of the previous pleural disease, the air within the pleural space is unable to extend to the spices, giving this unusual loculated appearance to the pneumothorax. So, in summary, a small pneumothorax can be easily missed.
