[Sonographic study of the spleen and retroperitoneal space-occupying masses]

Sonography of the spleen allows exact measurements of this organ. There are typical pictures in cysts or hematomas. Diffuse changes of the spleen however are hardly distinguishable in regard to differential diagnosis. Retroperitoneal masses can easily be recognized. Lymph-nodes can be identified and the results of therapeutic interventions can be judged. Hematomas or abscesses can be seen easily. Guided needle biopsy offers the possibility for histologic examinations.
