Unilocular Cysts of Ovary

The term unilocular has mainly a clinical significance :

it is rare to find an oophoriticcyst with only one cavity. A careful examination of such specimens will usually reveal numerous smaller loculi in the walls, or imperfect septa and bands of tissue passing
from one part of the cavity to another indicate that the cyst was originally compound. Many of the large onechambered^ cysts, described by early ovariotomists as ovarian, in many instances originated in the parovarium.
