Key clinical message
Celiac artery aneurysm is a rare and typically asymptomatic lesion that
is defined as dilation of the celiac artery trunk by 1.5 times its
normal diameter. Most are idiopathic and occur in the fifth decade of
life. Imaging plays an important role in the diagnosis and
identification of complications, such as expansion and thrombus
formation. 20% of cases are also associated with additional visceral
aneurysms, which imaging will help to localize.
We present the case of an elderly male patient in whom we performed
post-contrast computed tomography for a liver mass, which proved to be
focal nodular hyperplasia, and diagnosed an incidental and isolated
celiac artery aneurysm. We show the imaging findings and briefly review
the literature.
This case is important as it highlights how an imaging modality
performed for an unrelated condition can diagnose a rare visceral artery
aneurysm.
