Splenosis: 99mTc-labelled colloids provide the diagnosis in splenectomised patients

The diagnosis of abdominal splenosis is usually made by surgical biopsy of an abdominal mass incidentally discovered on abdominal ultrasonography, computed tomography or magnetic resonance imaging. To avoid exploratory surgery, 99mTc-sulphur colloid scintigraphy may be used: this technique is the most specific, easily performable, and cost-effective tool for the diagnosis of splenosis
