MRI of polysplenia syndrome.

ABSTRACT

The polysplenia syndrome is the association of multiple spleens, situs inversus, congenital heart disease, and azygous continuation of the inferior vena cava. Magnetic resonance (MR) is a noninvasive imaging modality which can easily confirm the multiplicity of spleens, situs inversus, and identify complex congenital cardiovascular malformations. The anomalies of the polysplenia syndrome as imaged by MR are presented.
