Ovarian Cysts (Theca Lutein Cyst)

Overview


Plain-Language Overview

Ovarian Cysts (Theca Lutein Cyst) are fluid-filled sacs that develop on the ovaries, which are part of the female reproductive system. These cysts form when the ovaries respond to high levels of certain hormones, especially during pregnancy or with hormone treatments. They are usually large and filled with clear, yellowish fluid. The cysts can cause the ovaries to enlarge, which might lead to abdominal discomfort or pain. Although often harmless and temporary, these cysts can sometimes cause complications if they grow too large or rupture. They are linked to conditions involving elevated human chorionic gonadotropin (hCG) levels. Monitoring and imaging tests are important to understand their size and impact on health.

Clinical Definition

Ovarian Cysts (Theca Lutein Cyst) are benign, multilocular cystic lesions of the ovary characterized by hyperplasia of the theca interna cells. They arise due to excessive stimulation by elevated human chorionic gonadotropin (hCG), commonly seen in conditions such as molar pregnancy, multiple gestations, or fertility treatments. These cysts are typically bilateral and can cause significant ovarian enlargement. Theca lutein cysts are part of the spectrum of functional ovarian cysts and represent an exaggerated physiological response rather than neoplastic growth. Clinically, they may present with abdominal pain or distension and carry a risk of ovarian torsion or rupture. Their recognition is important to differentiate them from other ovarian masses and to guide appropriate management.
