AIM: This report gives a comprehensive overview of ultrasonography of splenic abnormalities. Certain ultrasonic features are also discussed with pathologic correlation.
METHODS: We review the typical ultrasonic characteristics of a wide range of splenic lesions, illustrating them with images obtained in our institution from 2000 to 2003. One hundred and three patients (47 men, 56 women), with a mean age of 54 years (range 9-92 years), were found to have an abnormal ultrasonic pattern of spleen.
RESULTS: We describe the ultrasonic features of various splenic lesions such as accessory spleen, splenomegaly, cysts, cavernous hemangiomas, lymphomas, abscesses, metastatic tumors, splenic infarctions, hematomas, and rupture, based on traditional gray-scale and color Doppler sonography.
CONCLUSION: Ultrasound is a widely available, noninvasive, and useful means of diagnosing splenic abnormalities. A combination of ultrasonic characteristics and clinical data may provide an accurate diagnosis. If the US appearance alone is not enough, US may also be used to guide biopsy of suspicious lesions.
