Air-leak syndromes include pneumomediastinum, pneumothorax, pneumopericardium, pneumoperitoneum, pulmonary interstitial emphysema and subcutaneous emphysema. Pneumothorax and pneumomediastinum occur in 1 to 2% of normal neonates and they usually has no symptoms and resolves spontaneously. Here we report sudden fatal pneumomediastinum accompanied with pneumopericardium and pneumoperitoneum in no...

Subcutaneous and tissue space emphysema following surgical extraction of mandibular third molars is a rare and serious complication of dental surgery. Recognition of mediastinal emphysema following surgical extraction is difficult because there are no absolute clinical symptoms and signs. We present two cases of emphysema following extraction of a lower third molar and discuss the contribution ...

Subconjunctival emphysema is a condition that must theoretically exist in severe subcutaneous emphysema due to the laxity of the conjunctival tissues. However, this is generally obscured by associated periorbital emphysema and is hidden from view. We present documented evidence of subconjunctival emphysema in the absence of periorbital emphysema. A 53 year old man was admitted with a large righ...

Here, we present the case of a young man who, acting on his previously suppressed sexual fantasies, injected air into his penis and caused generalized subcutaneous emphysema.

Surgical emphysema of the larynx is rare in the absence of trauma and there are a paucity of case reports that describe such conditions. We present what we believe to be an unusual, atraumatic mechanism for mucosal breech of the larynx with subsequent surgical emphysema. Nasendoscopy revealed oedema of the arytenoid cartilage and computed tomography revealed moderate subcutaneous emphysema of t...

Physical examination revealed a dehydrated male with tachycardia and Kussmaul's respiration. There was subcutaneous emphysema in both supraclavicular regions. Chest auscultation revealed a positive Hamman's sign. Laboratory investigation was significant for metabolic a...
