Chest X-ray showing the features of pneumothorax on the left side of the person (right in image) It is not unusual for the mediastinum (the structure between the lungs that contains the heart, great blood vessels, and large airways) to be shifted away from the affected lung due to the pressure differences.
Catamenial pneumothorax is defined as at least two episodes of recurrent pneumothorax corresponding with menstruation. It was first described in 1958 when a woman presented with 12 episodes of right-sided pneumothorax over 1 year, recurring monthly with menstruation. Thoracotomy revealed thoracic endometriosis. [3]
The mean radiation dose to an adult from a chest radiograph is around 0.02 mSv (2 mrem) for a front view (PA, or posteroanterior) and 0.08 mSv (8 mrem) for a side view (LL, or latero-lateral). [1] Together, this corresponds to a background radiation equivalent time of about 10 days.
Chest x-ray demonstrating severe atelectasis or collapse of the right lung and mediastinal shift towards the right. Atelectasis is the partial collapse of a lung that is reversible. There are numerous etiologies, including post-operative atelectasis, surfactant deficiency, mucus plugging, and foreign body aspiration.
There are four technical grades: (1) Good; (2) Acceptable, with no technical defect likely to impair classification; (3) Acceptable, with some technical defect but still adequate; and (4) Unacceptable. Quality defects include over- or under-exposure, underinflation, artifacts, improper positioning, and others.
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
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.
In radiology, the deep sulcus sign on a supine chest radiograph is an indirect indicator of a pneumothorax. [1] [2] In a supine film, it appears as a deep, lucent, ipsilateral costophrenic angle [3] within the nondependent portions of the pleural space as opposed to the apex (of the lung) when the patient is upright.
