A Case of Complicated Hiatus Hernia Rupture Causing Tension Hydropneumothorax.

A 95-year-old female presented to the emergency department with chest pain and difficulty breathing. She had a left-sided tension hydropneumothorax secondary to a spontaneous rupture of a hiatus hernia close to the gastro-oesophageal junction. This has not previously been described in the literature and therefore, the purpose of this report is to pique clinicians' interest and highlight this rare phenomenon as a possible differential diagnosis in patients with a hiatus hernia who present with chest pain. It also demonstrates the importance of the use of oral contrast when using computerised tomography to investigate for oesophageal rupture.
