Hemolymphangiomatosis of the spleen: imaging features

J Comput Assist Tomogr. 2005 Nov-Dec;29(6):831-3. doi: 10.1097/01.rct.0000178713.40170.73.

Abstract

Hemolymphangiomatosis is an extremely rare entity that has never been described in the diffuse form. Its main pathologic feature is proliferation of lymphatic and vascular cells inducing interstitial and hematic lakes and then splenomegaly. We report a complete imaging study, including magnetic resonance (MR) imaging, after administration of a superparamagnetic contrast agent. Ultrasonography (US), basal MR imaging, and late computed tomography (CT) contrastographic features are quite similar to those of other diffuse benign vascular neoplasms, without real hemangioma-like enhancement during the vascular phase. Its late contrastographic pattern could be considered specific if CT and iron oxide-enhanced MR imaging are applied as complementary diagnostic tools, however.
