Pseudo-Meigs' Syndrome With Eosinophilic Pleural Effusion

Area of Science:

• Medicine
• Oncology
• Pulmonology

Background:

• Pseudo-Meigs' syndrome typically involves benign ovarian tumors, ascites, and exudative pleural effusion.
• Exudative pleural effusions in this syndrome usually show a predominance of mononuclear cells.

Observation:

• A 45-year-old woman presented with cough, sputum, and dyspnea.
• She had a large right pleural effusion, blood eosinophilia, ascites, and an ovarian tumor.
• The pleural fluid analysis revealed eosinophilia, indicating eosinophilic pleural effusion (EPE).

Findings:

• The ovarian tumor was diagnosed as a mature cystic teratoma after a left salpingo-oophorectomy.
• The patient's right-sided pleural effusion resolved following surgical treatment.
• This case highlights the exceptionally rare occurrence of EPE in pseudo-Meigs' syndrome.

Implications:

• This case expands the understanding of pleural effusion types associated with pseudo-Meigs' syndrome.
• It suggests that mature cystic teratomas should be considered in the differential diagnosis of unexplained EPE.
• Further research may be needed to elucidate the mechanisms linking ovarian teratomas to EPE.
