Tsüstilise is an Estonian adjective meaning cystic or relating to a cyst. It describes structures, lesions, or processes that have cyst-like characteristics. The form tsüstilise is an inflected form used with nouns in various cases, for example in phrases like tsüstilise moodustise (a cystic structure) or tsüstilise kahjustuse (a cystic lesion).

In medical and scientific language, tsüstiline is commonly used to characterize tissues or abnormalities that contain cysts or resemble cysts. It appears in terms such as tsüstiline kasvaja (cystic tumor), tsüstiline muutus (cystic change), and tsüstiline vorm (cystic form). The word is used across radiology, pathology, oncology and related fields to distinguish cystic from solid or other tissue characteristics. It can be combined with other prefixes or nouns to describe the nature and extent of cystic features.

Etymology and morphology: tsüstilise is formed from the noun tsüst (cyst) with the Estonian adjectival suffix -iline, yielding the meaning “cystic.” The base term tsüst is a loanword that has cognates in many languages (for example German Zyste, English cyst), reflecting a common medical root that traces back to Greek via European languages. The Estonian form adapts this root to fit standard adjective and case endings.

Related terms include tsüst, tsüstiline (cystic), and phrases describing cyst-related phenomena such as tsüstiliste moodustiste analiz (analysis of cystic structures). The concept is widely understood in medical contexts and appears in clinical descriptions, imaging reports, and scholarly articles.
