True about Meig&;s syndrome:
**Core Concept**
Meig's syndrome is a rare clinical entity characterized by the presence of a benign ovarian tumor, often a fibroma, associated with ascites and pleural effusion that resolve after tumor removal. This condition highlights the complex interplay between ovarian neoplasms and the body's fluid balance.
**Why the Correct Answer is Right**
The pathophysiology of Meig's syndrome involves the production of a substance by the ovarian tumor, such as inhibin or vascular endothelial growth factor (VEGF), which leads to increased capillary permeability and fluid accumulation in the abdominal and thoracic cavities. The resolution of ascites and pleural effusion after tumor removal suggests that the tumor is the primary source of the fluid accumulation.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Meig's syndrome is not associated with malignancy, unlike other ovarian tumors.
**Option B:** This option is incorrect because Meig's syndrome is not a form of pseudotumor or a manifestation of a different underlying condition.
**Option C:** This option is incorrect because Meig's syndrome is not primarily characterized by the presence of a specific type of ovarian tumor, such as a Brenner tumor.
**Clinical Pearl / High-Yield Fact**
Meig's syndrome is a rare but important clinical entity that highlights the need for thorough evaluation and management of ovarian neoplasms, including the resolution of associated fluid accumulation after tumor removal.
**Correct Answer:** D.
