This study is to determine the role of ultrasonography
(US) and computed tomography (CT) in improving splen
ic imaging and characterization of splenic pathology. Our
study included 92 patients. All patients were examined by
ultrasonography, including B mode, color and power doppler
US. Forty five of these patients were examined by
high resolution CT. The splenic lesions were 52 malignant
(40 lymphoma and 12 metastases) and 40 benign (10 in
farctions, 8 infections, 5 trauma, 6 cysts, 8 calcifications
and 3 haemangiomas). Malignant splenic lesions were hypoechoic
in 50 patients while splenomegaly was the most
common findings in CT. Ultrasonography plays a major
role in the detection of splenic lesions. US was more sen
sitive than CT in the detection of malignant lesions, partic
ularly splenic lymphoma, while US and CT were equally
effective in benign lesions. On CT, I.V. injection of conttast
material improved both the sensitivity of the exami
nation and the delineation of the abnormality.
