“…In the present study, there were no statistically significant differences between gender or age in sighthounds with the PIE and/ or pneumomediastinum compared with those without PIE and/or pneumomediastinum. Given the previously described association between the presence of spontaneous pneumomediastinum and the practice of strenuous activities in humans, 14,15 a predisposition to spontaneous pneumomediastinum could exist in sport‐oriented breeds such as sighthounds, which may be more likely to undergo intense exercise. Intense exercise was considered a likely predisposing factor in a previous case series of racing greyhounds with spontaneous pneumomediastinum, which had large volumes of mediastinal gas and clinical signs of dyspnea 9 .…”

Spontaneous pneumomediastinum is an uncommon condition described in veterinary medicine with concurrent respiratory disease. It can be caused by the Macklin effect, which is when gas leaks from the alveoli into the surrounding interstitial lung tissue. Pulmonary interstitial emphysema (PIE) is the presence of gas within the pulmonary vascular sheaths and indicates the presence of the Macklin effect. In the authors’ experience, spontaneous pneumomediastinum and PIE are more prevalent in sighthound dogs than in other breeds and are often considered incidental findings. This retrospective, observational, cross‐sectional study compared the prevalence of PIE and subsequent pneumomediastinum in sighthound with other purebred dogs. It characterized the appearance of PIE in CT and analyzed a possible association with concomitant pulmonary pathologies or with the use of general anesthesia. Medical records and thoracic CTs of sighthounds and nonsighthound dogs from two institutions were reviewed. A total of 256 dogs, comprising 127 sighthounds and 129 other purebred dogs, were included. The prevalence of PIE and pneumomediastinum was statistically higher in sighthound (14.2%) compared with other nonsighthound dogs (2.2%). There was no statistical association between the presence of PIE and pneumomediastinum with different age and weight groups or with sex. There was no statistical difference in the prevalence of PIE and pneumomediastinum between dogs with and without pulmonary pathology or in dogs undergoing CT with sedation or general anesthesia. Spontaneous pneumomediastinum in sighthounds is more prevalent than in other breeds, and its prevalence is not associated with the presence of pulmonary pathology or the use of general anesthesia.

“…SPM is not a routine provisional diagnosis in patients presenting with chest pain, accounting for only 0.3% of cases. In an absence of organic and primary lung pathology such as obstructive lung, SPM can be caused by an exertional increase in airway pressure induced by exertions that involve straining (weight lifting, defecation), forceful vomiting, difficult labor, and Valsalva maneuvers (Tobushi et al, 2015). This increase in airway pressure causes microtears in the alveoli, which leads to air shearing through the bronchovascular sheath into the mediastinum, leading to the development of pneumomediastinum.…”

The presentation of a paediatric patient with shortness of breath can be a common occurrence in the pediatric population presenting to the emergency departments with the majority of the illnesses in paediatric population can be attributed to shortness of breath. Recognition of life-threatening illnesses in a pediatric patient presenting to the emergency can be a challenge and thus having a low threshold of suspicion. Early recognition and treatment can be crucial and life-saving with the involvement of the right teams and the appropriate disposition of patients. In this case, we share a rare cause of shortness of breath in a child presenting to the emergency department.

A young man with a history of smoking presented with acute-onset chest pain after lifting weights. He also noticed a change in his voice, tightness in his neck and difficulty breathing. A chest radiograph showed soft tissue emphysema in the neck. A CT scan of the chest revealed moderate amount of pneumomediastinum tracking into the neck and down to the diaphragm. He was haemodynamically stable and had no hypoxia or dysphagia. He was monitored for 48 hours and discharged home after resolution of his symptoms. A chest radiograph repeated after 6 weeks was normal.
