Sonographic diagnosis of a subclinical wandering spleen: role of the decubitus position.

A wandering spleen is a rare condition. It is usually diagnosed when abdominal pain develops secondary to splenic torsion. Although splenic hypermobility is the pathognomonic feature of a wandering spleen, it is rarely revealed by imaging in the subclinical stage. We report 3 patients with a subclinical wandering spleen who had incidental sonographic findings of splenomegaly. Gray scale and color Doppler sonography in the right decubitus position can easily show the migratory nature and perfusion status of a wandering spleen in real time.
