Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta-human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.[1][2] On ultrasound and MRI, theca lutein cysts appear in multiples on ovaries that are enlarged.[3]
Theca lutein cysts are associated with gestational trophoblastic disease (molar pregnancy), choriocarcinomas, and multiple gestations.[4][5] In some cases, these cysts may also be associated with diabetes mellitus and alloimmunisation to Rh-D. They have rarely been associated with chronic kidney disease and hyperthyroidism.[6]
Usually, these cysts spontaneously resolve after the molar pregnancy is terminated. Rarely, when the theca lutein cysts are stimulated by hormones called gonadotropins, massive ascites can result. In most cases, however, abdominal symptoms are minimal and restricted to peritoneal irritation from cyst hemorrhage.[7] Due to the enlargement of the ovaries, there is an increased risk for torsion.[3] Surgical intervention may be required to remove ruptured or infarcted tissue.[7]
