Pseudo-Meigs syndrome is a rare condition characterized by the presence of a benign ovarian tumor, ascites (fluid accumulation in the abdomen), and pleural effusion (fluid accumulation in the chest cavity). It is named after the American gynecologist, Robert Meigs, who first described the condition in 1894. The condition is not associated with any other medical conditions and is usually treated with surgery to remove the tumor.

The symptoms of Pseudo-Meigs syndrome include abdominal pain, abdominal distention, pelvic mass, ascites (fluid accumulation in the abdomen), and elevated levels of CA-125 (a tumor marker). Other symptoms may include nausea, vomiting, fever, and weight loss.

The exact cause of Pseudo-Meigs syndrome is unknown. However, it is believed to be related to an underlying gynecologic condition, such as ovarian tumors, endometriosis, or pelvic inflammatory disease. Other possible causes include pelvic adhesions, pelvic congestion syndrome, and pelvic venous insufficiency.

The treatment for Pseudo-Meigs syndrome is typically focused on managing the underlying cause. This may include surgery to remove the tumor, chemotherapy, or radiation therapy. In some cases, hormone therapy may be used to reduce the size of the tumor. In addition, lifestyle modifications such as weight loss, exercise, and dietary changes may be recommended to help reduce the risk of recurrence.

The risk factors for Pseudo-Meigs syndrome include:

1. Advanced age
2. Female gender
3. Obesity
4. Hypertension
5. Diabetes
6. Endometriosis
7. Pelvic inflammatory disease
8. Previous pelvic surgery
9. Family history of ovarian tumors

At this time, there is no known cure for Pseudo-Meigs syndrome. Treatment typically involves medications to reduce the symptoms, such as diuretics to reduce fluid retention, and hormone therapy to reduce the production of ovarian hormones. Surgery may also be recommended to remove the affected ovary.
