Ascites is usually not difficult to detect with ultrasonography because of its characteristic lack of echoes. However, minimal or lobulated collections of fluid or unusual distributions due to anatomical variations or associated pathological processes may create problems in diagnosis. Differentiation from an intraperitoneal abscess, hematoma, lymphocele, or cystic mass is of considerable clinical importance.
由于腹水具有典型的无回声特征，通常不难通过超声检查发现。然而，少量或分叶状的液体积聚，或由于解剖变异或相关病理过程导致的异常分布，可能会在诊断上造成困难。与腹腔脓肿、血肿、淋巴囊肿或囊性肿块进行鉴别具有相当重要的临床意义。
