Ultrasound-Guided Aspiration Cytology of the Spleen

Abstract

The cytologic results of ultrasound-guided fine-needle biopsies (FNB) of the spleen in 42 patients were analyzed retrospectively. A focal lesion was punctured in 28 of them, splenomegaly in 12, and an enlarged accessory spleen in 2. Sufficient material was aspirated for cytologic analysis in 41 (97.6%) cases. A final diagnosis of malignancy was made in 16 (38%), and a benign condition diagnosed in 26 (62%) patients. The sensitivity, specificity, and accuracy of the method for differentiating malignancy from benign conditions were 68.8%, 100%, and 88.1%, respectively. No complications occurred. We conclude that ultrasound-guided FNB is a safe, highly specific, but relatively insensitive method of defining splenic pathology.
