Septated cyst
A septated cyst is a fluid-filled cystic lesion that contains internal dividing walls (septa), creating multiple compartments within the same cyst.[1]
General anatomy and imaging description
A septated cyst is described by the presence of one or more internal septa on imaging, rather than being purely unilocular (single cavity).[1]
Common clinical context
The term “septated cyst” is used across different body sites because many organs can develop cysts with internal septa.[1][2]
Key nuance
A septated cyst describes the cyst’s internal architecture and does not, by itself, determine the underlying cause or whether the lesion is benign or malignant.[1]
