Seurat spleen is an angiographic appearance seen following blunt trauma to the spleen. Multiple small punctate regions of intraparenchymal contrast extravasation lead to a spotted appearance.
Several mechanisms are thought to to attribute to this appearance which include sinusoidal stasis, traumatic artenio-venous aneurysm, contrast leakage from fragmented sinusoids, stasis of blood and contrast material within marginal sinuses because of contusion, hematoma and hypotension.
History and etymology
The term refers to a likeness between the angiographic appearance and the artwork of French impressionist Georges Seurat (1859-1891) who used a pointillist technique to create an image out of tiny dots .
