 Ultrasound, because of the simplicity of its use, and the excellent results obtained in practice for detecting tissue-quality differences, has become an indispensable means for the diagnosis of cysts of the pancreas. Besides the differentiation of cysts from solid tumors, it is useful in various aspects of clinical diagnosis, for instance, in the detection of small cysts which are hardly detectable by usual means, in the as-sessment of conditions of pseudocysts, in the manage-ment and the differentiation of neoplastic cysts from others. Cysts of the pancreas are mostly pseudocysts and retention cysts. Although neoplastic cysts are rare, it is clinically important to differentiate them accurately. In this article, ultrasound of neoplastic and non-neoplastic cysts is discussed from practical view points. The characteristic findings about neo-plastic cysts were stressed. Concerning non-neoplastic cysts, mostly pseudocysts, ultrasound was shown to be useful in demonstrating their morbid conditions and clarifying causative lesions.

 Recently, puncture technique performed during actual ultrasound monitoring has been applied not only to the diagnosis but also to the treatment of pseudocysts. Based on our results, percutaneous aspiration and drainage can be said to be useful for the treatment of acute pseudocysts with the rate of their resolution as high as 79%. Points indicated by our practical findings are discussed.
