This document discusses ovarian cysts, including their types, symptoms, diagnosis, and treatment. It covers functional cysts like follicular cysts and corpus luteum cysts versus non-functional cysts such as dermoid cysts. Ultrasound is the main diagnostic tool used to identify cyst characteristics. Most cysts are treated conservatively through observation, but surgery may be required for complicated cysts or cysts that cause symptoms. Potential cyst complications include ovarian torsion and rupture.
