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 showing an individual who had their right lung removed with fluid accumulating in the operated side. A pneumonectomy is a surgical procedure in which an entire lung is removed. A common reason for performing this procedure is for lung cancer originating in the lung itself. [ 19 ]
The reader compares the subject chest X-ray (only the appearances seen on postero-anterior, or PA, chest x-ray) with those of the standard set. The standard radiographs provide differing types ("shape and size") and severity ("profusion") of abnormalities seen in persons with pneumoconiosis, including Coal Workers’ Pneumoconiosis , silicosis ...
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 ...
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.
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 after menstruation. It may not necessarily occur with every menstrual cycle and in most cases is one-sided and on the right side.
