HYBRID SCINTIGRAPHY OF RARE SPLENIC HAMARTOMA

Splenic hamartoma, also known as splenoma, splenic adenoma or nodular hyperplasia, is a rare benign splenic tumor. It is composed of disordered vascular channels with abnormal mixture of red or white splenic pulp. Mostly it is asymptomatic and encountered incidentally at imaging, surgery or autopsy. Radiologically hamartomas are almost identical to hemangioma. In such circumstances radiolabelled blood pool imaging and radiocolloid scintigraphy helps to differentiate the two entities. We present a case of asymptomatic splenic lesion on hybrid radionuclide imaging with SPECT-CT, findings suggestive of hamartoma. Key Words: Splenic hamartoma, SPECT-CT, Radiocolloid scintigraphy
