Abstract
The MR and CT appearances of two cases of splenic hamartoma are presented. Computed tomography showed a well demarcated low-density mass without calcification. Dense spreading enhancement was seen in one case on dynamic CT, and prolonged enhancement was noted in both. The masses were demonstrated as areas of isointensity on T1-weighted MR images and of high intensity on T2-weighted images. On gadolinium-enhanced T1-weighted images they were shown as areas of high intensity. Prolonged enhancement on postcontrast CT and MR imaging was a useful finding in differentiation of splenic hamartoma from malignant lesions of the spleen, especially from nodular lesions of malignant lymphoma.
