Significant cases of<unk>  are easy to diagnose because of the characteristic signs of the condition. In some cases, the signs are subtle, making diagnosis more difficult. Medical imaging is used to diagnose the condition or confirm a diagnosis made using clinical signs. On a chest radiograph,<unk>  may be seen as radiolucent striations in the pattern expected from the pectoralis major muscle group. Air in the<unk>  tissues may interfere with radiography of the chest, potentially obscuring serious conditions such as pneumothorax. It can also reduce the effectiveness of chest ultrasound. On the other hand, since<unk>  may become apparent in chest X-rays before a pneumothorax does, its presence may be used to infer that of the latter injury.<unk>  can also be seen in CT scans, with the air pockets appearing as dark areas. CT scanning is so sensitive that it commonly makes it possible to find the exact spot from which air is entering the soft tissues. In 1994, M.T. Macklin and C.C. Macklin published further insights into the pathophysiology of spontaneous Macklin's Syndrome occurring from a severe asthmatic attack. The presence of<unk>  in a person who appears quite ill and febrile after bout of vomiting followed by left chest pain is very suggestive of the diagnosis of Boerhaave's syndrome, which is a life-threatening emergency caused by rupture of the distal esophagus.<unk>  can be a complication of CO2 insufflation with laparoscopic surgery. A sudden rise in end-tidal CO2 following the initial rise that occurs with insufflation (first 15-30 min) should raise suspicion of<unk> . Of note, there are no changes in the pulse oximetry or airway pressure in<unk> , unlike in endobronchial intubation, capnothorax, pneumothorax, or CO2 embolism.
