title: Dissecting the unspeakable: a fatal case of aortic dissection.
abstract: A 47-year-old man with diabetes and hypertension presented with sudden onset of chest pain and subsequently developed expressive aphasia. Brain imaging revealed multiple areas of ischaemic infarcts. Transoesophageal echocardiogram revealed aortic dissection with a free-floating thrombus on the dissection flap, which was the source of emboli. Given the poor prognosis, surgical intervention was not pursued and artificial support was withdrawn. Aortic dissection is a highly fatal condition with varied presentation including heart failure, myocardial infarction, neurological deficits, abdominal pain or acute renal failure. Aortic dissection is a relatively uncommon but catastrophic condition. A high degree of clinical suspicion is required for early and accurate diagnosis since mortality is high and increases by the hour. The mechanism for stroke in our case was due to an artery-to-artery embolism from a thrombus, which developed on the intimal surface of the dissected artery. This is an infrequent complication with a very unique mechanism.
