tsüstiline

Tsüstiline is an Estonian adjective meaning cystic, or relating to cysts. It is used in biological and medical terminology to describe tissues, structures, or conditions that involve or form cysts—saclike cavities that are typically lined by epithelium and filled with fluid or semi-solid material. The word is derived from the root tsüst (cyst) with the adjectival suffix -iline.

In medical descriptions, tsüstiline moodustis denotes a structure that contains a cyst or is built from cystic components, while tsüstiline muutus refers to a cystic change in tissue. The term is commonly applied to organs where cysts can occur, such as the kidneys or liver, and to various pathological or developmental states characterized by cyst formation. It is also used when describing findings in medical imaging, where tsüstiline lesions appear as fluid-filled cavities on ultrasound, CT, or MRI.

Usage notes: tsüstiline serves as a descriptive modifier rather than a disease name by itself. It often appears in phrases like tsüstiline moodustis, tsüstiline muutus, or tsüstilised muutused in reference to observations in pathology reports or radiology notes. The plural form tsüstilised moodustised or tsüstilised muutused may be used depending on grammatical context.
