Fatal Tension Gastrothorax: Two Case Reports.

Tension gastrothorax is a rare and potentially fatal complication of a diaphragmatic hernia, in which a massively dilated, intrathoracic stomach compresses the lungs and mediastinum, causing cardiorespiratory compromise, in a mechanism akin to tension pneumothorax. Although it is very rare, tension gastrothorax has been reported in the literature; however, such reports are almost exclusively restricted to its clinical presentation and treatment in emergency departments. To the best of our knowledge, no adult autopsy case reports of tension gastrothorax have been reported in the literature. We present 2 adult autopsy case reports in which we believe the cause of death was tension gastrothorax, followed by a discussion of what a tension gastrothorax is and its potential etiology, and finally, we discuss the difficulties of making the diagnosis at autopsy, including how postmortem computed tomography imaging can be hugely beneficial as it was in one of our cases.
