Splenic Vein Aneurysm Demonstrated by Magnetic Resonance Angiography

Abstract

Splenic vein aneurysm (SVA) is an extremely rare vascular abnormality (1, 2). We report a SVA in a rheumatoid arthritis (RA) patient which was demonstrated by Doppler sonography, contrast-enhanced computed tomography (CT), and magnetic resonance angiography (MRA). The present case is the tenth SVA patient reported in the English literature. Furthermore, this is the first case of a SVA which was demonstrated by MRA. The literature regarding this entity is discussed and the characteristic MR angiographic appearance of a nonthrombosed splenic vein aneurysm is presented.
