Classical Meig syndrome is associated with which of the following ovarian tumour :
**Core Concept**
Classical Meig syndrome is a rare clinical condition characterized by the presence of a benign ovarian tumor, ascites, and pleural effusion, which resolve spontaneously after the removal of the tumor. This condition highlights the complex interplay between ovarian pathology, fluid dynamics, and the body's response to tumor presence.
**Why the Correct Answer is Right**
The correct answer is associated with a type of ovarian tumor that is known to cause Meig syndrome due to its propensity to produce ascites and pleural effusion. **Mucinous cystadenomas** are a type of ovarian tumor that can lead to Meig syndrome, likely due to the production of fluid by the tumor, which accumulates in the peritoneal cavity and pleural space. The removal of the tumor leads to resolution of the symptoms, demonstrating a clear causal relationship.
**Why Each Wrong Option is Incorrect**
**Option A:** **Serous cystadenomas** are a different type of ovarian tumor that can also cause ascites and pleural effusion, but they are not typically associated with Meig syndrome. This is because serous cystadenomas rarely produce the type of fluid accumulation characteristic of Meig syndrome.
**Option B:** **Dermoid cysts** are a type of ovarian tumor that can cause various symptoms, but they are not typically associated with Meig syndrome. Dermoid cysts are more likely to cause symptoms due to their solid components and potential for torsion or rupture.
**Option C:** **Granulosa cell tumors** are a type of sex cord-stromal tumor that can cause various symptoms, including ascites and pleural effusion, but they are not typically associated with Meig syndrome. These tumors can produce estrogen, leading to various systemic symptoms, but they are not characteristically associated with fluid accumulation characteristic of Meig syndrome.
**Clinical Pearl / High-Yield Fact**
Meig syndrome is a rare but important condition to recognize, as it highlights the complex interplay between ovarian pathology and fluid dynamics. Remember that **mucinous cystadenomas** are the ovarian tumors most commonly associated with Meig syndrome, and their removal can lead to resolution of symptoms.
**Correct Answer:** A. Mucinous cystadenomas.
