Excerpt
A 33-year-old female with a history of recurrent idiopathic thrombocytopenic purpura and significant thrombocytopenia, status post splenectomy, presented for a damaged red blood cell (dRBC) scan. After injection of 15 mCi of
99mTc-labeled dRBC, planar dRBC images (
A: anterior image) showed no convincing evidence of splenic remnants. Therefore, SPECT/CT acquisition (Siemens Symbia, Malvern, PA, USA) was performed. Three small soft tissue masses were demonstrated in the left upper abdomen on CT, and all of them displayed increased uptake on co-registered SPECT images. In the selected plane shown in
B 1 –
B 3 (
B 1 , SPECT;
B 2 , CT;
B 3 , fusion image; transaxial views), only one of these three splenic remnants (
red arrows) is visualized as a small soft tissue mass demonstrating significant uptake on the SPECT and SPECT/CT images.
