Isolated pleural effusion is a rare presentation of ovarian hyperstimulation syndrome. The pathogenesis of this disorder has not been fully elucidated. It supports the role of systemic factors rather than transudation of fluid from the surface of enlarged ovaries. This article describes a rare case of isolated pleural effusion following controlled ovarian hyperstimulation during an in-vitro fertilization cycle.
Keywords: In-vitro fertilization; ovarian hyperstimulation syndrome; pleural effusion.
