Magnetic resonance imaging-based diagnosis of aortitis preceding development of a thoracic aneurysm in a patient with giant cell arteritis: a case report.

Magnetic resonance imaging can detect silent, generalized manifestations of GCA such as severe aortitis, which may possibly lead to aneurysmatic dilatation, urging closer follow-up imaging. Detection of the ongoing process and subsequent follow-up imaging protects patients by avoiding rupture.
