The authors report the case of a 47-year-old man who suffered a diving accident. After regaining consciousness he experienced severe headache. He was initially treated for barotrauma, but the persistent headache led to diagnostic imaging that revealed an aneurysmal subarachnoid hemorrhage. To the authors' knowledge, this is the first report of a ruptured brain aneurysm associated with barotrauma.
