Septated cyst
A septated cyst is a fluid-filled cyst in which internal partitions (“septa”) divide the cavity into separate compartments. This finding is most often described on imaging (ultrasound, CT, or MRI).
Imaging characteristics
Septations are internal thin or thicker dividing walls within the cyst. The presence of septa suggests a multicompartment structure rather than a single uniform fluid space.
Clinical significance
The clinical significance depends on the cyst’s location, size, patient age, symptoms, and imaging features beyond septations (such as wall thickness, mural nodules, solid components, or enhancement). Septations alone do not establish whether the cyst is benign or malignant.
Common contexts where septated cysts are described
Septated cysts may be reported in several settings, including ovarian cysts, breast cysts, and other soft-tissue or abdominal cystic lesions. The interpretation must follow the specific organ’s imaging criteria.
Next diagnostic steps
Further evaluation is guided by the cyst’s anatomic site and imaging descriptors. Referral to the appropriate specialty (such as gynecology, breast imaging, or surgery) and follow-up imaging may be recommended when concerning features are present.
