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.
The main symptom is usually severe central chest pain. Other symptoms include laboured breathing, voice distortion (as with helium) and subcutaneous emphysema, specifically affecting the face, neck, and chest. [4] Pneumomediastinum can also be characterized by the shortness of breath that is typical of a respiratory system problem.
The double bronchial wall sign is commonly seen in the central bronchi, particularly in the trachea or mainstem bronchi, where air is more likely to outline the structures. Associated findings such as air surrounding other mediastinal structures, such as the esophagus or great vessels may be present.
While many causes of lower left abdominal pain can be managed at home through lifestyle changes and over-the-counter remedies, persistent or severe symptoms require professional medical evaluation ...
Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity. The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. Pneumatosis intestinalis, air or gas cysts in the bowel wall; Gastric ...
Air in subcutaneous tissue does not usually pose a lethal threat; [4] small amounts of air are reabsorbed by the body. [8] Once the pneumothorax or pneumomediastinum that causes the subcutaneous emphysema is resolved, with or without medical intervention, the subcutaneous emphysema will usually clear. [18]
A primary spontaneous pneumothorax (PSP) tends to occur in a young adult without underlying lung problems, and usually causes limited symptoms. Chest pain and sometimes mild breathlessness are the usual predominant presenting features. [12] [13] In newborns tachypnea, cyanosis and grunting are the most common presenting symptoms. [14]
Hamman's sign (rarely, Hammond's sign [1] or Hammond's crunch [2]) is a medical sign consisting of a crunching, rasping sound, synchronous with the heartbeat, [3] heard over the precordium in spontaneous mediastinal emphysema. It is thought to result from the heart beating against air-filled tissues.
