This form of liver cancer is called primary liver cancer. Noncancerous, or benign, liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In most cases, benign liver tumors are not detected because they cause no symptoms.
The typical radiograph is of a well-defined, rounded, retrocardiac opacity with an air-fluid level. In this image, the radiolucent gas is highlighted in blue, while the gastric contents are highlighted in the green. In many cases of hiatal hernia, there will not be an air bubble below the left hemidiaphragm. This is a relatively expected finding considering that the stomach is no longer in its usual position. The anatomical position of the herniated organ can be further elucidated on the lateral radiograph. Here we can see that the stomach is in the middle mediastinum posterior to the heart and above the diaphragm. Hiatal hernias can look similar to a retrocardiac lung abscess or another cavitary lesion, but it will change in size and shape between radiographs. Large hernias can shift the mediastinum to the right and result in a widening of the carinal angle. They can even give the appearance of cardiomegaly. In this radiograph, the cardiac silhouette is distinctly visible within the confines of the hiatal hernia. To review, a hiatal hernia on an AP chest radiograph typically appears as a round retrocardiac opacity with an air-fluid level.

A flail chest occurs when a segment of the thoracic cage is separated from the rest of the chest wall. This is usually defined as at least two fractures per rib (producing a free segment), in at least two ribs. A segment of the chest wall that is flail is unable to contribute to lung expansion. Large flail segments will involve a much greater proportion of the chest wall and may extend bilaterally or involve the sternum. In these cases the disruption of normal pulmonary mechanics may be large enough to require mechanical ventilation.

The type of operation performed for removal of pancreatic cancer is based on the location of the tumor. For tumors of the head and neck of the pancreas a Whipple procedure, (also called a pancreaticoduodenectomy) is performed. This is a complex operation perfected at Johns Hopkins. This video will explain the surgery and what patients can expect.

Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.
