Retroperitoneal fibrosis presenting as colonic dysfunction: CT diagnosis.

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,...
