Frontal view of the abdomen with double bubble sign, patient was found to have duodenal atresia. In radiology, the double bubble sign is a feature of pediatric imaging seen on radiographs or prenatal ultrasound in which two air filled bubbles are seen in the abdomen, representing two discontiguous loops of bowel in a proximal, or 'high,' small bowel obstruction.
The diagnosis of duodenal atresia is usually confirmed by radiography. An X-ray of the abdomen is the first step in evaluation. The x-ray should be obtained after placement of a nasogastric tube (feeding tube), evacuating the stomach and filling 40-50 ml of air [5] to demonstrate two large air filled spaces, the so-called "double bubble" sign.

High obstruction can be suspected based on the double bubble sign. Cases without distal gas are usually related to duodenal atresia, while high obstruction with distal gas need an upper gastrointestinal series because of the need to distinguish duodenal web , duodenal stenosis and annular pancreas from midgut volvulus , the latter being a ...
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
The dark areas on both sides of the intestines indicate that air is present in both sides. This is called "Rigler's sign". A radiologic sign is an objective indication of some medical fact (that is, a medical sign) that is detected by a physician during radiologic examination with medical imaging [1] (for example, via an X-ray, CT scan, MRI scan, or sonographic scan).

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.
