Abstract

Asymptomatic splenic nodules were detected incidentally in two middle-aged women at an annual checkup. They showed no abnormalities on laboratory tests, but imaging studies revealed splenic nodules. No other localized lesions were found. Splenic nodules were hypoechoic on ultrasonography (US), hypovascular on contrast-enhanced computed tomography, and showed a low intensity on T2-weighted magnetic resonance imaging. We performed US-guided percutaneous aspiration biopsies using 21-gauge needles without complications, including bleeding. Pathological specimens showed noncaseating granulomas, so both patients were diagnosed with isolated splenic sarcoidosis. A US-guided fine-needle aspiration biopsy is a safe and useful method for diagnosing splenic nodules.
