Broadly speaking, neoplastic cysts are usually complex, meaning that they're larger than 10 centimeters, have irregular borders, and have internal septations creating a multilocular appearance.

说，赘生性的囊肿比较复杂，大小会超过10厘米，边界不清；内部有隔断，形成房状的外观。

Some originate from surface ovarian epithelium, such as serous cystadenomas, which are often bilateral and filled with a watery fluid, and mucinous cystadenomas, which tend to be multilocular and contain a mucus-like fluid.

其中有些起源卵巢上皮，例如卵巢浆液性囊腺瘤，常双侧卵巢，充满水样液体；以及黏液性囊腺瘤，为房，内含黏液。
