Ultrasound is the method of choice in the detection and differentiation of solid or cystic masses in the abdomen. The differential diagnosis of anechoic and hypoechoic lesions comprises a large variety of benign and malignant diseases or abnormalities. This paper describes a number of such lesions and, in addition, discusses the possible differential diagnoses so far reported in the literature. An attempt is made to describe the different features of such lesions. Most of them are rare but have to be considered if a lesion of unknown origin or clinical relevance is detected by ultrasound.
超声是检测和鉴别腹部实性或囊性肿块的首选方法。无回声和低回声病变的鉴别诊断包括多种良性和恶性疾病或异常情况。本文描述了一些此类病变，并讨论了文献中迄今报道的可能的鉴别诊断。试图描述此类病变的不同特征。其中大多数病变较为罕见，但如果超声检测到来源不明或具有临床意义的病变，则必须予以考虑。
