Carbohydrate antigen 125 (CA -125) is widely used as a tumor marker for ovarian cancer, but elevations can occur in benign conditions, leading to diagnostic dilemmas. We report a case of markedly elevated CA 125 in a 62-year-old woman due to pericardial effusion secondary to idiopathic pericarditis. Her CA -125 normalized following pericardiocentesis and treatment, highlighting the importance of interpreting tumor markers within clinical context.
