Aortic dissection is gaining recognition in Western societies, and it is being diagnosed
with increasing frequency. New diagnostic imaging modalities, longer life expectancy,
as well as the increase in the number of patients suffering from hypertension have
all contributed to the growing awareness of aortic dissection. Nevertheless, as many
as 30% of patients ultimately diagnosed with acute dissection are first thought to
be suffering from something else. The increased availability and use of multidetector
computed tomography have led to the incidental discovery of aortic dissection in very
different settings. This article focuses on unusual presentations of painless aortic
dissection. It is important for radiologists to remember that aortic dissections may
present in different ways, not only as an acute, critical fatality but also with subtle,
unusual signs and symptoms, which apparently do not seem to be strictly related to
aortic diseases.
