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 Tc-labelled Sn-colloid is able to detect splenic tissue and in our opinion is a simpler and less time-consuming procedure than using 99m Tc DRBC.

Brain metastases are a rare complication of prostate cancer. They are usually diagnosed in an end-stage disease when the tumor has already spread to the other organs and tissues. We present a case of a male with castration-resistant prostate cancer with bone metastases visualized in ¹⁸F-fluorocholine PET/CT scan.

Hybrid SPECT/CT lymphatic mapping yields a high SLN detection rate in patients with early-stage breast cancer and provides lymph node localization details. It identifies more SLN than planar imaging and intraoperative SLN detection. However, its limited superiority over the remaining two methods does not support its routine use for SLN localization. We suggest using SPECT/CT for SLN detection in case of equivocal planar imaging results.
