What is splenosis?
Splenosis is the spread of splenic tissue anywhere within the torso, most commonly in the peritoneal cavity, due to prior trauma or splenectomy. This is a potential mimic of peritoneal spread of tumor, although the attenuation, signal intensity, and enhancement properties are similar to those of normal splenic tissue. Uptake of 99m Tc sulfur colloid or 99m Tc heat damaged red blood cells on scintigraphy is diagnostic.
