Ultrasonography of hemorrhagic splenic cysts.

Cysts arising from the spleen are much less common than those arising from other organs such as kidney, liver, and ovary (1). Hemorrhagic cysts of the spleen are rare (1), but we have encountered two patients with this entitiy. The ultrasonograms in each patient demonstrated gravity-dependent layering of two fluids of distinctly different echogenicity. The fluids were contained within a spherical mass. Acoustic enhancement was exhibited behind the mass in each case. This suggested the diagnosis of hemorrhagic cyst.
