Tension pneumothorax is a rare and potentially life-threatening clinical complication. A 43-year-old Caucasian woman with type 1 diabetes mellitus presented with nausea and retching and examination revealed dehydration. Laboratory parameters were consistent with a diagnosis of diabetic ketoacidosis, which responded to therapy. Suddenly, 30 hours later, she developed cardiorespiratory compromise due to a tension pneumothorax. After emergent decompression and catheter placement, computerized tomographic scan of the chest demonstrated esophageal-pleural fistula confirming Boerhaave syndrome as the etiology for the pneumothorax. The patient underwent emergent esophagectomy with pleural washout with a subsequent gastric pull-up surgery. Boerhaave syndrome frequently presents atypically with chest pain, dyspnea, and nausea. It communicates with the left pleural space in 80% to 90% of cases, but <5% of cases involve the right pleural cavity. Unexplained and rapidly progressive pleural effusions have been associated with this entity. Only 4 cases of Boerhaave syndrome causing tension pneumothorax have been reported in the literature so far.

Hamman's syndrome is a spontaneous pneumomediastinum and is described as a rare complication of diabetic ketoacidosis (DKA). It typically follows a self-limiting course after successful treatment of the underlying DKA. We describe a case of a 28-year-old woman with type 1 diabetes presenting with facial pain, vomiting and abdominal pain. She also complained of dyspnoea and chest pain. She was diagnosed and treated for DKA triggered by a dental abscess. Given the presentation during the coronavirus pandemic, a computed tomography pulmonary angiography was performed in line with the diagnostic pathway for COVID-19, which incidentally showed a significant pneumomediastinum and pneumopericardium. The patient was initially investigated for oesophageal rupture secondary to vomiting (Boerhaave's syndrome), however, remained clinically stable throughout. Follow-up computed tomography showed near-complete resolution of pneumomediastinum with no intervention other than treatment of DKA. This therefore confirmed Hamman's syndrome.We propose that given the benign nature of the condition and the incidental finding in this report, as well as poor identification of mediastinal gas on chest X-ray, Hamman's syndrome is more common than reported.
