Typical appearance of splenosis in a patient with a remote history of traumatic splenic rupture and splenectomy. This can be mistaken for peritoneal carcinomatosis, particularly given the number of small omental nodules, but notice that there is no omental thickening, ascites, or diffuse peritoneal thickening/nodularity. The larger cluster in the right pelvis increases the confidence that this is splenosis.

The patient was offered a nuclear medicine study to confirm the diagnosis (heat damaged RBC or sulfur colloid) but declined. MRI with ferumoxytol is another option for confirming the benign diagnosis.
