Splenic hamartoma presenting as a "hot spot" on Tc-99m phytate SPECT imaging.
The cases of two patients with surgically proven splenic hamartomas with "hot spots" on Tc-99m phytate SPECT imaging are presented. There was intense radiocolloid accumulation in the peripheral portion of a large single tumor in one patient, and in each of three isolated tumors in the other patient. The intense uptake might be related to the function of proliferated reticuloendothelial cells in the tumors. These unique findings were not clearly identified on the planar images.
