Traumatic pericardial rupture is a rare lesion associated with a high mortality rate, and its diagnosis poses challenges for the surgeon. Two patients are presented, in whom the diagnosis was not possible preoperatively, and discovered only during surgery for associated lesions. To the best of our knowledge, this is the first description of total bilateral linear pericardial ruptures associated with traumatic aortic rupture. The mechanism, diagnostic challenges, and management of this rare entity are discussed.
