This paper presents a case of an 80-year-old man with idiopathic
thrombocytopenic purpura after splenectomy performed many
years ago, which normalized platelet count, presented with severe
thrombocytopenia with no response to treatment. A SPECT/CT
study was performed using 99mTc-labelled Sn-colloid. The histology
confirmed the presence of splenic tissue in those foci. Spleen
examination (SPECT/CT) using 99mTc-labelled Sn-colloid is able
to detect splenic tissue and in our opinion is a simpler and less
time-consuming procedure than using 99mTc DRBC.
