Sonography of focal lesions of the spleen

Abstract

The sonographic appearances of benign and malignant splenic lesions in 154 patients are illustrated. Sixty-six of the 154 patients had malignant splenic lesions; 55 of these had malignant lymphoma and 11 had splenic metastatic lesions. The lesions were hypoechoic in 64 cases (97%), including all cases of malignant lymphoma, and were hyperechoic in two. Eighty-eight patients had benign splenic lesions; findings included cysts, infarcts, abscesses, hemangiomas, and calcifications.
