In contrast, tension pneumothorax is a medical emergency and may be treated before imaging – especially if there is severe hypoxia, very low blood pressure, or an impaired level of consciousness. In tension pneumothorax, X-rays are sometimes required if there is doubt about the anatomical location of the pneumothorax. [16] [18]
Catamenial pneumothorax; Pneumothorax shown on a chest x-ray. Air fills the space between the collapsed left lung and the chest wall. Specialty: Pulmonology: Symptoms: Chest or shoulder pain, shortness of breath: Usual onset: 30-40 years of age: Causes: Thoracic endometriosis: Risk factors
On radiological studies, pneumothorax is visualized using conventional chest x-rays and CT scans. In 90% of the cases, the pneumothorax is located on the right side. In some cases, small nodules can be seen in the pleura using CT scans. Confirmation can be done using video assisted thoracoscopic surgery (VATS). [8]
On chest x-ray, the most frequent sign is air trapping that can lead to a mediastinal shift. Atelectasis and pneumothorax may also occur in the setting of foreign body aspiration. The diagnosis is made in conjunction with clinical symptoms and confirmed and treated with bronchoscopy. [22]
Other conditions that can produce similar symptoms include pericarditis, heart attack, cholecystitis, pulmonary embolism, and pneumothorax. [3] Diagnostic testing may include a chest X-ray, electrocardiogram (ECG), and blood tests. [3] [6] Treatment depends on the underlying cause. [3]
A chest X-ray can rapidly identify a pneumothorax, seen as absence of lung markings. Ultrasound can show the lack of lung sliding. However, imaging should not delay treatment. [8] CT angiography is the standard of diagnosis of pulmonary embolism. Clots appear in the vasculature as filling defects. [18]
Hydropneumothorax is defined as the presence of both air and fluid within the pleural space. [1] An upright chest x-ray will show air fluid levels. The horizontal fluid level is usually well defined and extends across the whole length of one of the hemithorax.
Thoracic endometriosis is characterised by onset of the following clinical symptoms within 24 hours prior to and 72 hours after onset of menses. Catamenial pneumothorax: this is the most common clinical manifestation, present in 80% of cases. Catamenial pneumothorax is defined as a recurrent pneumothorax that occurs within the first 72 hours ...
