- Definition/Triad
- A benign, solid ovarian tumor (classically a fibroma).
- Ascites (fluid in the abdomen).
- Pleural effusion (fluid around the lung), which is typically right-sided.
- Key Feature: Complete resolution of ascites and pleural effusion after surgical removal of the tumor.
- Pathophysiology
- Ascites: The exact mechanism is unclear. Theories suggest that irritation of the peritoneum by the large, solid tumor or secretion of fluid from the tumor itself leads to fluid accumulation. Tumors are often >10 cm.
- Pleural Effusion: Ascitic fluid is thought to migrate into the pleural space via transdiaphragmatic lymphatic channels or small defects in the diaphragm. The fluid can be a transudate or an exudate.
