appear as large, bilateral cystic masses rather than a unilateral mass.
| Presentation | • Multilocular • Bilateral • 10-15 cm ovaries | | --- | --- | | Pathogenesis | • Ovarian hyperstimulation (markedly elevated β-hCG) due to: ◦ Gestational trophoblastic disease ◦ Multifetal gestation ◦ Infertility treatment | | Clinical course | • Resolve with decreasing β-hCG levels |
Theca lutein cysts are expectantly managed as they resolve after treatment of the hydatidiform mole by suction curettage or hysterectomy when the β-hCG level decreases.
