Abstract:
Objective:To analyze the conventional ultrasound（CUS）and contrast-enhanced ultrasound（CEUS）features of hepatic lymphoma，and to investigate the value of CEUS in the diagnosis of hepatic lymphoma.Methods:The images of 39 patients（39 lesions）with hepatic lymphoma pathologically confirmed by surgery and puncture from March 2012 to July 2024 at Zhongshan Hospital，Fudan University were retrospectively analyzed. Evaluations of CUS included the echogenicity，morphology，color Doppler flow imaging（CDFI）situation，evaluations of CEUS included enhancement type，enhancement degree compared to the peripheral normal liver parenchyma and time to enhancement.Results:In the 39 lesions，hypoechoic lesions were detected in 31（79.49%，31/39）patients on CUS. CDFI detected linear or branched color flow signals inside the lesions in 21（53.85%，21/39）lesions，and peripheral color flow signals around the lesions in 3 lesions，while arterial flow signals were detected in 16 of them，with a resistance index of 0.50～0.77（0.67 ± 0.02）. In addition，signs of non-compacted normal blood vessels passing through the lesions were detected in 5 lesions. After injection of contrast medium，39 lesions showed different degrees of enhancement，mainly showed entirety homogeneous enhancement，during the arterial phase of CEUS，34（87.18%，34/39）lesions showed fast enhancement，and when the enhancement reached the peak，26（66.67%，26/39）lesions revealed hyper-enhancement，showing “fast progression”. There were 38（97.44%，38/39）lesions in the portal and delayed phases showed “fast forward”.Conclusions:CUS and CEUS can provide some value in the diagnosis and differential diagnosis of hepatic lymphoma.
