Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.
Chest x-ray of a five-year-old girl with Scimitar syndrome. The heart (blue outline) is shifted into the right half of the chest, and the anomalous pulmonary venous return (red) has a shape reminiscent of a Scimitar. The diagnosis is made by transthoracic or transesophageal echocardiography [citation needed] and selective pulmonary angiography. [5]
Pneumonia as seen on chest X-ray. A: Normal chest X-ray. B: Abnormal chest X-ray with consolidation from pneumonia in the right lung, middle or inferior lobe (white area, left side of image). Specialty: Pulmonology
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 ...
The abnormal chest x-ray and its interpretation remain the most important factors in establishing the presence of pulmonary fibrosis. [11] The findings usually appear as small, irregular parenchymal opacities, primarily in the lung bases. Using the ILO Classification system, "s", "t", and/or "u" opacities predominate. CT or high-resolution CT ...
Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way. [4] If the patient has a history of smoking or the nodule is growing, the possibility of cancer may need to be excluded through further radiological studies and interventions, possibly including surgical resection. The prognosis depends on the underlying condition.
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.
